I purchased the VJ series, but I can't remove the main unit from the socket.

The VJ Series are compact, but the line-up includes versatile I/O specifications, wide-range of power supply, isolated two outputs and field configurable models.

The VJ series limit alarms are compact, plug-in type alarm setting devices with easy-to-use functions. Four models are available: the VJAK for 2-wire system transmitters; the VJHK with DC voltage/DC current inputs; the VJRK with RTD inputs; the VJTK with thermocouple inputs; and the VJUK with universal inputs.

Compact size, plug-in style and microprocessor based high performance capabilities (Multi-function types) makes the VJ Series Signal Conditioners 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.
