Function

This signal conditioner provides the galvanic isolation between field circuits and control circuits.

The device is a relay module that is suitable for safely switching applications of a load circuit. The device isolates load circuits up to 60 V DC and the 24 V DC control circuit.

The energized to safe (ETS) function is permitted for SIL 3 applications.

An internal fault or a line fault is signalized by the impedance change of the relay contact input and an additional relay contact output. A fault is signalized by LEDs and a separate collective error message output.
