Featuring single-pole, normally closed design, 800 V Model PLB171P is designed to provide 7 mm of separation between 2 output pins and uses optically coupled MOSFET technology to provide input-to-output isolation of 5,000 Vrms. Optically coupled outputs are controlled by infrared LED. Designed to replace electromechanical relays, PLB171P provides bounce-free switching in compact surface-mount package. It is suited for industrial controls, meters, AC line voltage equipment, and multiplexers.
