Multispan Single-Phase Solid State Relay

Multispan SSR-40DA solid state relay provides silent, spark-free switching of AC loads up to 40A using a 3–32V DC control signal from a PLC or microcontroller. Used for temperature controller output stages, electric heater switching, UV lamp control, and anywhere electromechanical relays cause noise or require frequent switching. Includes zero-crossing switching to reduce EMI.
