Single Phase Direct Current Solid State Relay DC to AC
The Single Phase Direct Current Solid State Relay DC to AC control inputs are connected internally to an LED, which shines across an air gap to light sensors.The light sensor is connected to the transistors which open or close, supplying the relay's load with power.When a transistor is closed, current can flow freely through the relay, causing the load and power supply to be connected. When a transistor is open, almost all current is blocked, causing the load to become disconnected from the power supply. The pairing of an LED with light sensors is called an optocoupler, and is a common technique to link two parts of a circuit without a direct electrical connection.
