Description
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. 4-channel isolated barrier, 24 V DC supply (Power Rail), Dry contact or NAMUR inputs, 50 % less wiring, 2:1 technology, Relay contact output, Line fault detection (LFD), Reversible mode of operationpa. 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.
