What's the purpose of an interface relay?

An interface relay electrically isolates sensitive control circuits from higher-power loads. It enables a low-power signal from the PLC or control system to switch higher currents and voltages required for industrial devices.

How long will the relay last?

This product has a lifespan of 50,000 electrical operations and five million mechanical operations, giving you long-term performance.
