The RP1A23D5 is a 1-pole zero cross-switching Solid State Relay for use with PCB mounting, It provides an ideal interface between logic controls and AC loads. The RP1 is designed for resistive and inductive loads up to 480VACRMS. Two regulated control voltage ranges cover most standard input requirements. This feature allows a direct substitution of existing PCB mounted relays with RP1. Internally this new series enjoys an improved technical design with the introduction of stress-free flexible encapsulation and automated assembly of components. Opto-isolation and load switching are performed by individual components, providing higher reliability than monolithic designs. Additionally RP1 is a special version with high current surge capability that reduces fusing requirements. The solid state technology used can withstand peak voltage of 1000V, making the RP1 series suitable to drive AC loads such as valve solenoids and small induction motors.
