SSR-25DD solid-state relay

Category: .

A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. SSR consist of a sensor which responds to an appropriate input (control signal), a solid-state electronic switching device which switches power to the load circuitry, and a coupling mechanism to enable the control signal to activate this switch without mechanical parts. The relay may be designed to switch either AC or DC to the load. It serves the same function as an electromechanical relay, but has no moving parts .It’s also called non-contact switch.

SSR own high reliability : there isn’t any mechanical part inside SSR, and it uses totally-enclosed encapsulation structure ,therefore , SSR owns characteristics of resistance to shock , moisture , corrosion , long service life and reliable.

Main Application:

Industrial automation installment, AC motor control, Intermediate relay,solenoid valve control, Numerical control machinery,external guidnance system,computer periphery connection, Illumination,stage lighting control, Electric stove,heating,warm control, street light,signal light,traffic light,Color photo enlargement,film processing equipment,injection machinery,Automatic fire control and security system,etc.
