Description
The relay isolation drive control module, the core is an electronic control device relay, with a control system (also known as an input loop) and a controlled system (also known as an output loop), which is essentially a “automatic switch that uses a smaller current to control a larger current” “. Used to control 10A 250V AC, 10A 30V DC load, with output signal indicator. Adopt 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.
Product characteristics:
1. With output signal indicator
2. The signal input port can be connected to the single-chip IO port, driven by high-level signals
3. Dual power supply design, strong anti-interference ability, photoelectric isolation protection and high reliability.
4. Onboard 3V, 10A/250VAC; 10A/30V DC relay. Can be continuously attracted 100,000 times, with diode discharge protection, short response time
5. The external connection adopts rotary crimping terminal to make the connection more firm
6. With fixed mounting holes for easy installation
Interface Description:
Power interface:
VCC: Connect to the positive pole of the power supply (3.3V)
GND: Connect to the negative pole of the power supply
IN: high level control relay pull-in
Load interface:
NO: Normally open interface of the relay, the relay is suspended before pull-in, and shorted to COM after pull-in
COM: Relay common interface
NC: Normally closed interface of the relay, the relay is short-circuited with COM before pull-in, and hangs up after pull-in
