Connection
Assembly
• 1-channel isolated barrier
• 115 V AC supply
• Dry contact or NAMUR inputs
• Relay contact output
• Line fault detection (LFD)
• Reversible mode of operation
• Up to SIL2 acc. to IEC 61508/IEC 61511
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.
The proximity sensor or switch controls a form C changeover
relay contact for the safe area load. The barrier output
changes state when the input signal changes state. The
normal output state can be reversed using switch S1.
Switch S3 is used to enable or disable line fault detection of
the field circuit.
During an error condition, the relay reverts to its de-energized
state and the LEDs indicate the fault according to
NAMUR NE44.
