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.Product FeaturesVoltage: DC 3V/3.3VSize: 70*17*20mmMain components: EL817, SRD-DC03V-SL-CCan control 10A 250VAC, 10A 30VDC loadFeatures:1. With output signal indicator light;2. The signal input port can be connected to the IO port of the microcontroller, and driven by high-level signals;3. The dual power supply selection design has strong anti-interference ability and high reliability of photoelectric isolation protection;4. With diode freewheeling protection;5. The response time is less than 20 milliseconds;6. The relay has a long life and can be continuously attracted for 100,000 times;7. The external connection uses a rotating crimping terminal to make the wiring more secure;8. With fixed mounting holes for easy installation.
