Below is a relay wiring diagram that shows how to use a relay switch with an NPNtransistor. This is useful for when you want to control a relay from things that can’t drive relays, like an Arduino, or an integrated circuit from the4000 seriesor7400 series. The NPN transistor’s base ...
Optocouplers are always operated by DC voltage not by AC voltage. Therefore in this type of relay, the supply is first rectified to DC and then applied to opto for switching. On the output side, the AC load is connected. AC-DC configuration.In this configuration, a rectifier circuit is ...

the relay and the input share the same VCC, and when it is open, a separate power supply must be provided to the JD-VCCjumper to power the relay coil and optocoupler output.

This isolates (electrically) the low-voltage control side from the high-voltage load side. Such a setup is called anoptocoupler. The light sensor activates the trigger circuit, turning on the switching device in the output circuit, thereby connecting the power source to the load. The switching ...

This is referred to as ACTIVE LOW meaning the circuit is active/on when it is low. The ground of the supply for the relay and the RPi ground should be connected, and then when the GPIO is LOW it would turn ON BUT again with the 8.3v you ...
The 100 mA output current capability of the integrated step-down (featuring overload and short-circuit conditions) can be used to supply both the VREG pin and other application components (for example digital isolators or optocouplers). Active per-channel current limitation (0.7 A and 1.0A ...
