Introduction

The solid-state SIR series relays are designed for industrial applications requiring rugged, reliable operation. These relays provide an optically-isolated, high-capacity, solid-state output with power switching capability up to 20 A steady state, 200 A inrush. The SIR2 zero voltage switching is intended for resistive and incandescent loads and can extend the life of an incandescent lamp up to 10 times. The SIR1 random switching is intended for inductive loads. When fully insulated female terminals are used on the connection wires, the system meets the requirements for touch-proof connections.
