Connection

Assembly

• 2-channel isolated barrier

• 24 V DC supply (Power Rail)

• Dry contact or NAMUR inputs

• 2 x 2 relay contact outputs with AND logic

• Line fault detection (LFD)

• Reversible mode of operation

• Up to SIL2 acc. to IEC 61508

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 two form A normally open

relay contacts for the safe area load. The normal output state

can be reversed using switches S1 and S2. Switch S3 is used

to enable or disable line fault detection of the field circuit.

During an error condition, the relays revert to their de-

energized state and the LEDs indicate the fault according to

NAMUR NE44.

A unique collective error messaging feature is available when

used with the Power Rail system.
