Function

This isolator product is suitable for intrinsically safe applications. The device is used to transmit digital signals (from NAMUR sensors or dry contacts) from the field area to the safe area. Each input controls a single passive transistor output. The operating mode can be inverted via a switch, and the line fault detection function can be disabled. Faults are indicated according to NAMUR NE44 by an LED indicator and a separate collective fault signal output.
