Series: SLR

The solid-state SLR Series Relays are designed for industrial applications requiring rugged, reliable operation. These relays have no isolation between the control switch input and the solid-state output and should be used in systems where the control switch is the same voltage source as the load. The SLR Series provides the reliable, noiseless, and long life of a solid-state relay without the cost of isolation circuitry. The zero-voltage switching SLR2 model can extend the life of an incandescent lamp up to 10 times its normal life. The random-switching SLR1 model is normally used for inductive loads. When fully-insulated female terminals are used on the connection wires, the system meets the requirements for touch-proof connections.

Operation The solid-state output is located between terminals 1 and 2 and can be ordered as either normally open or normally closed when voltage is applied and S1 is open. When S1 is closed, the solid-state output between terminals 1 and 2 closes (or opens). If S1 is opened, the solid-state output will open (or close).
