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.
Features
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.

Solid state relay module AC/DC Solid state relay SSR2-40DA
DIMENSIONS SHOWING:
OPERATION NOTICE:
1.Resistive load could not exceed 60% of the rated current.
2.Inductive or capacitive load could not exceed 40% of the rated current.
3.Electric machine load could not exceed 20% of the rated current.
4.Proper radiator adapted to the working requirement of solid state relay should be equipped, the allowance should be widened when the load radiating condition is not so good. Short-circuit load is not allowable.
5.Over Current Protection: over current and short circuit are the main reasons for permanent damage of output controllable silicon in the SSR, and using fast fuse and air switch is one of methods for over current protection, fuse is also available for small capacity.
6.Over Voltage Protection: It can adopt parallel voltage-dependent resistance(MOV), the MOV area decides the absorption power, while its thickness decides the protective voltage value, generally, 471/10D voltage-dependent resistance for 220V series SSR, 681/10D voltage-dependent resistance for 380V series SSR, 821/10D voltage-dependent resistance for 480V series SSR.
