Conversion Circuit Solid State Relay Overheat Protection Function Standard
Solid State Relay Description:
Solid state relay is a four-terminal active device, two of which are input control terminals, and the other two are output controlled terminals. It has both amplifying and driving functions and isolation functions and is very suitable for driving high-power switching actuators, Compared with the electromagnetic relay, the reliability is higher, and it has no contact, long life, fast speed, and little interference to the outside world, and has been widely used.
Solid State Relay Features:
1. 4A for load current
2. Load voltage can reach 280VAC
3. Zero-cross and non-zero-cross as trigger mode
4. Dielectric withstand voltage 3000VAC
