LW3111 1-Channel Intrinsically Safe Digital Input Isolator for NAMUR Sensors

The LW3111 is an intrinsically safe digital input isolator for hazardous-area NAMUR proximity sensors and passive switches. It isolates the switching signal and transmits it to the safe-area PLC/DCS through relay, logic-level or transistor output. An optional line-fault detection function can identify input wiring faults.
