Members of the NIVELCO UNICONT PKK-312 series can be described as 4-20 mA current controlled limit switch with galvanic isolation. Also available as an intrinsically safe attachment. 4–20 mA input signals can be transmitted from passive or active outputs of 2- or 4-wire transmitters.
The value of the input signal will be compared with the value set (taught) in the unit and the state of the galvanically isolated relay will change according to the programmed comparison mode.

Galvanic Isolation Analog Current Controlled Limit Switch Application Areas
Extending a process control system with 2 relays or 2 current outputs
For mixed systems: version with 1 relay and 1 current output
Provides galvanic isolation (Galvanic isolation is used to divide the input and output sources of a device to allow current to flow through a field or electrical connections.)
