·         50 % less wiring, 2:1 technology

·         Relay contact output

·         Line fault detection (LFD)

·         Reversible mode of operation

Function :

This isolated barrier is used for intrinsic safety applications. It transfers digital signals 

(NAMUR sensors/mechanical contacts) from a hazardous area to a safe area. 

Each sensor or switch controls one form A normally open relay contact for the safe area load. A special 2:1 wiresaving technology is 

available on this isolator, reducing field wiring by 50 %. Switch S1 is used to enable or disable line fault detection of the field circuit.

The 2:1 mode is selected with switch S2 while the remaining switches, S3 ... S6, are used for reversing the normal output state of the relays. 

A unique collective error messaging feature is available when used with the Power Rail system.
