High Level Driver Module Optocoupler Relay Module Isolated Drive Control Board for Arduino SRD-DC03V-SL-C



Relay isolation drive control module
The relay isolation drive control module, the core is the electronic control device relay, with control
Control system (also called input loop) and controlled system (also called output loop),
The essence is-a kind of "automatic switch" that uses a smaller current to control a larger current. Used to control 10A
250VAC, 10A 30VDC load, with output signal indicator. Adopt double
Power selection design to enhance anti-interference ability. So it plays an automatic adjustment and safety in the circuit
Protection, conversion circuit and other functions.
Product parameter


Features:


1. With output signal indicator
2. The signal output can be connected to the IOD of the single-chip microcomputer, driven by a high-level signal
3. The dual power supply selection design has strong anti-interference ability and high reliability of photoelectric isolation protection
4. Onboard 3V, 10A/250V AC; 10A/30V DC relay, which can be connected continuously
100,000 times, with diode effusion protection, short response time
5. The external connection adopts rotary crimping terminal to make the connection more firm
6. With fixed mo
