Brainboxes releases the US-159 small profile USB to Serial device with isolation. We have given our customers the ‘just works’ reliable USB to Serial connection they have come to expect from Brainboxes but with the added security of isolation, perfect for demanding industrial environments.

The US-159 gives an RS-232 serial connection on one end with a high retention USB connection of the other. All connections are electronically isolated from one another in our smallest toughest case yet.

The US-159 case is in our ultra-small form factor, and can cope with industrial temperatures, is IP50 rated and has a high retention USB connection. Really tough, can’t be snapped or crushed and is well sealed limiting ingress from dirt and moisture and works from -40°C to +80°C (-40°F to +176°F).

Isolation prevents electrical damage to your expensive equipment. The US-159 has 2kV of isolation protecting from high voltage spikes, and ground potential difference. With all the different equipment and power sources factories are environments where power spikes and disturbances can be a common problem. Isolation can go a long way to protecting your equipment from these variations.

Increasingly laptops come without serial ports and small form factor PCs are losing ports too. Many substandard USB to Serial solutions are unreliable. Customers reported to us that they need add on products to be as small as possible as they were often limited for space. They also needed a strong connection as the product was taking the weight of a heavy Serial cable.

Robust High Retention USB B Type Connector has a withdrawal force of 3.2lbs. (15N) making it 50% stronger than traditional USB. High retention eliminates accidental disconnections and the USB connector won’t snap under weight of connecting cables. High retention cables give the secure connection of an integrated solution but still have the flexibility of the detachable/changeable cables.

If you’ve used our USB to Serial products before you’ll know the software is trouble free, with great compatibility and works where many others fail. That same software, with drivers for all latest Microsoft OS including Windows 8.1 comes with the US-159.

The US-159 with isolation is a good choice for environments with lots of electrical interference, but it can be used in any of the following environments for added piece of mind: Banking, Configuration for System Admins, Maintenance engineers, Configuring PLC and CNC machines, CAD systems, Broadcast, Home automation, small form factor embedded PCs with limited expansion options. It’s for anyone who needs a portable Serial port they can depend on when they are on site.

Stronger, smaller, smarter – our best ever USB to Serial.

Hitachi America, Ltd., Industrial Components and Equipment Division, today announced the introduction of the SJ700D Series of Industrial AC Variable Frequency Drives,  with  full  availability  in  February.  The  SJ700D  significantly  expands  on  the  performance, capabilities and functions of both its predecessors, the SJ700 and the SJ700B.

Hitachi has once again broadened the applicability of this new series by incorporating and upgrading many of the original flagship SJ700 features and incorporating them into a new, more versatile variable frequency drive package. Therefore, the new SJ700D drives are ideal for a complete wide range of applications beyond variable torque applications such as fans and pumps, or constant torque applications such as material handling or extrusion equipment. The new SJ700D also has a number of built-in features that make the commissioning process quick and easy, such as single parameter change (b049) to set the drive as either a variable torque or constant torque all while offering the end user a trouble-free control.

Another notable upgrade in the SJ700D dual rated inverter is the higher operating temperature range of -10°C to 50°C. The SJ700D is further enhanced from its predecessors with a new faster processing scan time for our exclusive internal programming feature, Hitachi's EzSQ (Easy Sequence), our built-in programming function, which provides the functionality of a PLC built into the inverter. Due to this internal capability, in many cases, the need for a separate PLC can be eliminated or the I/O reduced. Multiple programs for various applications such as irrigation pump control or condition specific motion profiles can be developed on a PC and then downloaded to the inverter with the easy-to-use ProDriveNext software provided at no charge from our website.

The other new helpful features Hitachi has added to the SJ700D include the changes to the EzSQ run parameters that allow an additional free intelligent input, as well as 5 retentive memory locations for use from within the program structure.

Add to these some new operational and protective features, such as output phase loss protection to make sure your application is protected from every angle, to the new faster (115.2k baud rate) Modbus RTU communications to make sure all the data necessary in your process is received in a timely manner, and we have one very versatile and powerful variable frequency drive. The SJ700D also retains all the features that make this such a popular choice, such as our patented micro-surge voltage suppression to protect the motor winding insulation, advanced trip avoidance functions, configurable sink/source logic on digital inputs, user defined analog and digital outputs, PID, built-in dynamic braking circuit in models up to 40 HP (30 kW,) and built-in EMC filters in all models.

The SJ700D incorporates all the features customers have come to expect from Hitachi Variable Frequency Drives, which provide the end user with a reliable, high quality and high value variable frequency drive.

A truly globally accepted product, the SJ700D is CE, UL, c-Tick-certified and RoHS-compliant.

Hitachi America, Ltd., Industrial Components & Equipment Division, today announced the new SJ700-2200HFU2 model inverter, with a 440 A output current capability. This new model fills in the gap at 300-350 hp in the SJ700 series, which now completely covers the range from ½ to 600 hp.

The SJ700 significantly expands on the performance, capabilities and functions of its predecessor, the SJ300. Hitachi reasserts its technological leadership with an improved vector control algorithm and auto-tuning function that enables the open-loop SJ700 (SLV) to develop more than 200% starting torque at 0.3 Hz. Using Hitachi’s unique “0 Hz Domain” open-loop control mode, the SJ700 can develop 150% torque near 0 Hz, ideal for vertical lift applications. In closed-loop mode with encoder feedback, the SJ700 performance is unmatched, delivering in excess of 100% torque at 0 Hz.

Another major new element in the SJ700 is Hitachi’s EzSQ (Easy Sequence) built-in programming function. It’s like having a PLC inside the inverter! In many cases, the need for a separate PLC can be eliminated. The user develops EzSQ programs on a PC, and then downloads them to the inverter using the simple-to-use configuration/programming software provided at no charge.

The SJ700 can deliver true servo-like position control when mated with a general-purpose induction motor and encoder, offering a low-cost motion control alternative. The SJ700, given a position command, speed command, and acceleration/deceleration times, can move the motor shaft from position A to position B following the defined profile and then maintain the shaft in “servo lock” status.

Hitachi has added other new features into the SJ700, such as patented micro-surge voltage suppression (to protect the motor winding insulation), advance trip avoidance functions, configurable sink/source logic on I/O, built-in dynamic braking circuit in models up to 30 hp (22 kW), built-in EMC filter up to 75 hp (55 kW).

The SJ700 also includes built-in RS485 Modbus/RTU communication, and options for other communications networks, such as Ethernet Modbus/TCP, DeviceNet, Profibus and LonWorks. Others, such as Ethernet/IP are in the works. The SJ700 can be configured via the front-mounted keypad or using Hitachi’s ProDrive PC-based software.

Designed to be a product for the global market, the SJ700 carries CE, UL, cUL and c-Tick marks, and is RoHS compliant.

Hitachi America, Ltd., Industrial Components & Equipment Division, today announced two new 100 V Class models in the innovative WJ200 series of inverters. The new models are rated at ½ hp and 1 hp, 100-120 VAC, single-phase input, and 200-240 VAC, 3-phase output.

The WJ200 series sets a new benchmark for performance, flexibility and functionality in micro-size AC drives. The WJ200 is a sensorless vector (SLV) drive capable of 200% or greater torque across the speed range. Speed regulation at low speed is dramatically improved – fluctuation is half that of previous models. Improved trip avoidance measures have been incorporated for unsurpassed system reliability and availability.

The WJ200 is distinguished by its integrated PLC-like functionality. With its powerful Easy Sequence (EzSQ) logic controller function, programs up to 1024 lines can be created on a PC using a structured language editing tool. These programs can then be transferred to the WJ200 to control its operation and allow very sophisticated control schemes to be created without the use of external controllers.

Simple position control applications are also possible with the WJ200 utilizing the integrated pulse input. Together with EzSQ, intricate motion profiles can be developed. Further adding to its flexibility, the WJ200 has the capability to drive both induction motors and permanent magnet (PM) motors – a single drive for two motor realms.

A new EzCOM peer-to-peer communications function is standard and allows multiple WJ200s to share data. One drive is designated as the “administrator,” and controls the network. Other drives on the network can be master or slave, with masters able to write data to any designated slave(s). Master/slave roles are rotated under the control of the administrator automatically. Up to 8 masters can reside on the network, and up to 32 drives (up to 247 drives, if external signal repeaters are used). The administrator can be master or slave also. EzCOM allows for creation of sophisticated coordinated systems without any additional external hardware or programming.

Other desirable standard features include a safe-stop function (meets ISO/IEC standards), password protection of parameters, real-time clock, standard Modbus/RTU RS-485 serial port, micro surge voltage suppression, dynamic braking circuit, and much more. The WJ200 is designed for long service with bus capacitors and cooling fans designed for 10 year life and varnish coating of circuit boards. The WJ200 also is RoHS compliant. Option boards will be released in the near future to allow communication via Ethernet/IP, DeviceNet, CompoNet, ProfiBus, CANopen, and others.

Hitachi America, Ltd., Industrial Components and Equipment Division, today announced the introduction of the SJ700B Series of Industrial AC Variable Frequency Drives, with full availability in late October. The SJ700B significantly expands on the performance, capabilities and functions of its predecessor, the L700.

To reassert its technological leadership and ensure unmatched performance, Hitachi has broadened the applicability of this new series by incorporating and upgrading many of the original flagship SJ700 features, such as the industry-leading Sensorless Vector (SLV) control algorithm. This algorithm enables the SJ700B to develop 120% of full torque capabilities at 0 Hz in Hitachi’s exclusive “0 Hz Domain” sensorless vector control mode, as well as 150% torque at 0.5 Hz in sensorless vector operation mode in most models, which is ideal for a wide range of applications beyond just fans and pumps. Additionally, operation in the closed-loop full vector control mode is now possible as well through an optional board. The SJ700B also has a number of built-in features that make the commissioning process quick and the operation of the control trouble-free.

Another notable upgrade in the SJ700B is the higher operating temperature range of -10°C to 45°C . The SJ700B is loaded with additional application integration features such as Hitachi's EzSQ (Easy Sequence) built-in programming function, which provides the functionality of a PLC built into the inverter. Due to this internal capability, in many cases, the need for a separate PLC can be eliminated or the I/O reduced. Programs for various applications such as irrigation pump control or repeatable motion profiles can be developed on a PC and then downloaded to the inverter with the easy-to-use EzSQ software provided at no charge.

The other new helpful features Hitachi has added to the SJ700B include the patented micro-surge voltage suppression to protect the motor winding insulation, advanced trip avoidance functions, configurable sink/source logic on digital inputs, PID, built-in dynamic braking circuit in models up to 40 HP (30 kW,) and built-in EMC filters in all models.
