Switch Amplifier Features Assembly -channel isolated barrier 30 V AC supply Dry contact or NAMUR inputs Relay contact output Line fault detection (LFD) Reversible mode of operation Up to SIL acc. to IEC 6508/IEC 65 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. Switch 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.
