Function

This isolated barrier is used for intrinsic safety applications.

The device transfers digital signals (SN/S1N proximity sensors or approved dry contacts) from the explosion-hazardous area to the non-explosion-hazardous area.

The input controls one active voltage output and one passive transistor output with a resistive output characteristic acc. to EN 60947-5-6.

The passive transistor output has three defined states: 1-signal = 1.8 kΩ, 0-signal = 14 kΩ and fault > 100 kΩ.

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

During a fault state, both 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.

Unlike a SN/S1N series safety sensor, an approved dry contact requires a 10 kΩ resistor to be placed across the contact in addition to a 1.5 kΩ resistor in series.

This device mounts on a HiC termination board.
