The UNICONT PJK-1-4 is a universal interface module that can be controlled via HART or MODBUS protocol through an RS485 interface, and (depending on type) provides relay(s) and/or 4…20 mA current output(s). The device is intelligent, the internal functions and services can be set with the help of a communication protocol: the transmitter outputs can be scaled. The error detection function can be switched on and off. The state, in which a given output unit should be when an error occurs, can also be set. The device can be used with Nivelco’s MultiCONT PR -1- units as an output extension module, and also as a peripheral device for PLC or PC controlled process control systems.
