Pepperl+Fuchs HiC2831R2 Manual

Function
This isolated barrier is used for intrinsic safety applications.
The device transfers digital signals (NAMUR sensors/mechanical contacts) from the explosion-hazardous area to the non-explosion-
hazardous area.
The input controls two passive transistor outputs with a resistive output characteristic.
The outputs have three defined states: 1-signal = 5 kΩ, 0-signal = 15 kΩ and fault > 100 kΩ.
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.
During a fault state, the passive transistor outputs switch to their fault state and LEDs indicate the fault according to NAMUR NE 44. A separate
fault bus is available. This fault bus can be monitored if the termination board supports a module fault detection.
This device mounts on a HiC termination board.
