Function
This signal conditioner provides the galvanic isolation between field circuits and control circuits.
The device transfers digital signals (NAMUR sensors or dry contacts) from the field to the control system.
Each input controls a relay contact output.
Via switches the mode of operation can be reversed and the line fault detection can be switched off.
A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output.
