Product name: Single-channel 3V high-level relay isolation control module (with optocoupler isolation control)

The core of the 3/3.3V relay isolation drive control module is the electronic control device relay, which has a control system (also known as an input circuit) and a controlled system (also known as an output circuit). It is essentially an "automatic switch" that uses a smaller current to control a larger current. It is used to control 10A250VAC, 10A30VDC loads, and has an output signal indicator light. It adopts a dual power supply selection design to enhance anti-interference capabilities. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuits in the circuit.
