Solid-state relay (SSR) is to package the light-controlled thyristor and light-emitting diode together to ensure electrical
isolation between the two, and generate signal transmission by emitting light. Compared with mechanical relays, which control contacts through coils, solid-state relays control thyristor circuit on and off by switching on and off the luminescent tube, which has the same function as ordinary electromagnetic relays.

3-32VDC
OUTPUT CURRENT
40A
TYPE
3 PHASE
Introduction to the use of the product
Multiple SSRS can use the same trigger signal, which is often used in the control of three-phase AC loads. For example, two SSRS are connected in series in two phases and the other phase is not controlled. In this case, the two SSRS must be switched on and off at the same time, and the same trigger signal can be used to ensure simultaneous action. At this time, the trigger circuits of the two SSRS are connected to drive. Each SSR is considered by 4V voltage drop, and three can be driven by 12V.
