Yokogawa VJH1-026-AAA0 JUXTA VJ Series Signal Conditioners

Compact size, plug-in style and microprocessor based high performance capabilities (Multi-function types) makes the VJ Series an excellent choice for almost every application. Analog output, Hi-Low alarm relay outputs or RS-485 MODBUS communication is available as optional second output. Various parameters such as input range and computation programs can be set and modified using a PC (VJ77) .

Specifications

• Compact design for space saving.
  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.
