Solid state relays use electronic components for switching a load, have no moving parts, and are ideal for applications requiring many/frequent contact closures. Models include general-purpose relays in panel or DIN rail mounting styles.

Solid State Relays
Category Selection
Solid state relays employ electronic components (MOSFETs, Triacs, etc.) in place of mechanical parts to control the on/off state of a circuit. Unlike electromechanical relays which can have a service life in the millions of cycles, solid state relays have a virtually infinite lifespan and will not wear out over time.
They are available in panel mount "hockey puck" or DIN rail mounting styles and use the zero-cross switching type. Zero-cross solid state relays wait for the AC signal to cross zero before energizing and are ideally suited for most commercial and industrial loads such as resistive heating elements, lamps and ballasts, and any other load with low initial impedance or capacitive characteristics. They are preferred in applications with some level of capacitance as they can minimize surge currents during the first conduction cycle.
