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 a passive transistor output with a resistive output characteristic. 

The outputs have three defined states: 1-Signal = 6.5 V voltage drop, 0-Signal = 33 kolihm and 6.5 V voltage drop and fault > 100 kolihm. 

This output characteristic offers line fault transparency on the signal lines. 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.
