The relay isolates the drive control module, the core is the electronic control device relay, which has a control system (also known as a transmission circuit) and a controlled system (also known as an output circuit), which is essentially an “automatic switch” that uses a smaller current to control a larger current. It is used to control 10A 250VAC, 10A 30VDC load, and has an output signal indicator prompt. Dual-power supply selection design to enhance anti-interference ability. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.Parameters:It has an output signal indicator.The signal transmission population can be connected to the IO port of the single-chip microcomputer, and the high-level signal is driven.The dual-power supply selection design has strong anti-interference.ability and high reliability of optoelectronic isolation protection.Onboard 3V, 10A/250V AC; 10A/30V DC relay for 100,000 consecutive pick-ups, with diode leakage protection and short response timeThe external wiring uses a rotary crimp terminal to make the wiring more secureWith fixed mounting holes for easy installationPower Connector:VCC: Positive (3.3V)GND: Connect to the negative pole of the power supplyIN: High level control relay engagementLoad Interface:NO: Normally open interface of relay, the relay is suspended before engagement, and is short-circuited with COM after engagementCOM: Relay common interfaceNC: Normally closed interface of relay, short circuit with COM before relay engagement, and suspended after relaying
