Function

This isolated barrier is used for intrinsic safety applications.
The device transfers digital signals (NAMUR sensors or dry contacts) from a hazardous area to a safe area.
Each input controls an active transistor 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.
