Description

Relay isolation drive control module 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. Using double Power selection design to enhance anti-interference ability. So it plays an automatic adjustment and safety in the circuit Protection, conversion circuit, etc.

Product parameter: 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. Dual power supply selection design has strong anti-interference ability and high reliability of photoelectric isolation 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 mounting holes, easy to install

Power interface: VCC: Connect the positive pole of the power supply (3.3V) GND: connect to the negative pole of the power supply IN: High level control relay pulls in Load interface: NO: The relay normally open interface, the relay is suspended before it is closed, and it is shorted to COM after it is closed COM: Relay common interface NC: Relay normally closed interface, the relay is short-connected with COM before it is closed, and it is suspended after it is closed
