The external dimensions are 76 H×29.5 W×124.5 D (mm). - Power supply voltage is either 100 to 240 V AC or 15 to 30 V DC.
- The standard withstand voltage : 2000 V AC
Between Input - Output - Power - Ground - Two isolated outputs*
Second isolated current or voltage (pulse) output is available as optional feature. - Communication function*
Optional MODBUS (RS-485) communication function can be obtained simultaneously with analog output signal from one VJ. - Alarm outputs*
Bi-directional relay of HART communication signals is possible while the field devices and the DCS are isolated from each other. - Field configuration*
If you have a computer with the VJ77 parameter setting tool installed, you can set up the microcomputer-based VJ on site. - Three years warranty*
- Supports overseas safety and EMC standards (CE, UL, CSA, etc.)*
- Universal input
You can configure the VJU7 Temperature Converter for input from thermocouples, RTDs, or mV signals. - HART communication signal relay function (VJA1/H, VJH1/HC)
You can perform HART communication between field devices and DCS that have the HART function (isolated between input and output). - Output open detection function (VJH1/C, VJH1/HC)
Enables detection of the open state of an isolated load circuit with the input device.

Taking advantage of sensors already available in your system, you can simply add VJ series signal conditioners or the UM33A Digital Indicator with Alarms to easily build a monitoring system on a PC.

Load devices are sometimes used when evaluating (measuring) DUT performance. Depending on the parameter being evaluated, multiple controllers can be employed to control the performance of the load device, but there are also times when the load device uses only one actuator.
Przegląd:
With advances in process automation comes a greater need for level measurement and control. As pressure on at the bottom surface of a liquid is proportional to the height of the liquid's surface, you can measure pressure using a differential pressure transmitter to detect the level of the liquid, acquire the data on the UT75A Digital Indicating Controller, and use the measurements to control the tank level.

- Effeciently controls the inlet valve and blow-off valve when the compressor starts and stops.
- During steady operation, controls the inlet valve so that the amount of discharged compressed air becomes constant (flow control)
- Surging: Load decreases, the amount of discharge flow and pressure drop, and a limit is exceeded, possibly destroying the compressor.
