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 230 V AC and the 24 V DC control circuit.
The de-energized to safe (DTS) function is permitted for SIL 3 and PL e 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.
The output must be protected against contact welding by an internal fuse or an external current limitation.
