Ac Solid State Relay Wiring Diagram
Download Ac Solid State Relay Wiring Diagram Images. A solid state relay (ssr) is an electronic switching device that switches on or off when an external voltage (ac or dc) is applied across its control terminals. Solid state relays (ssr) are electronic switches that use transistors as switching components the circuit wiring diagram of the heat sink type dip pcb mounting dc to dc solid state relay is the same as the dip dc to dc solid state relay.
Since an scr conducts for only half the cycle, to switch an ac power supply it is necessary to put a single scr in a bridge configuration or use two scrs in inverse parallel configuration, as shown in figure 9.
If the device is energized with short circuit or any wrong connection, it may cause unexpected malfunction, abnormal heat or fire. It is a difficult subject, but to keep it short, it will last much longer and by clean switching. A solid state relay or ssr, features these electronic devices. In 120vac applications, l2 is neutral and must not be fused or switched.
