The active barrier is used for transmission and galvanic isolation of 4 to 20 mA/HART signals. The device has an active/passive current input to which a 2- or 4-wire transmitter can be connected directly. The output of the device can be operated actively or passively. The current signal is then available to the PLC/controller or for further instrumentation at pluggable screw or optional push-in terminals.
