Relay Module 8-way relay 12V with optocoupler isolation PLC low-level trigger control board Tips: This module has 12V8 relay output module, 250V 10A relay output contact. Inputs IN1, IN2, IN3, IN4, IN5, IN6, IN7, IN8 signal lines are active low. VCC, GND power input terminal, JD-VCC relay power input terminal can be powered separately. Usage: 1. Support all MCU control.2. Industrial field; 3. PLC control4. Smart home control;Features:Using a high current relay, AC250V 10A DC30V 10AP Free wiring of contact parts, safe and reliable Standard interface, can be extended on various development boards By installing screw holes for easy installation Suitable for various platforms such as 51/AVR/AVR /ARMP Description of the module:1. This module complies with international safety standards, and there is an isolation slot between the control area and the load area;2. It adopts FR-4 double-sided circuit board design and high-end chip production technology;3. Use Songle relay control; 4. With relay action indicator, it is bright when it is on, but not when it is off;5. When there is a low-level signal at the signal input terminal, the normal terminal and the normally open terminal will be conducted; 6. relays can control various equipment and loads directly; 7. There are 8 normally open and 8 normally closed contacts;8. the blue KF301 terminal is easier to connect to the control line.9. Module size: 138m * 56mm * 18.5mm (length * width * height), net weight: 120g10. There are 4 fixing bolt holes, the hole is 3.1mm, and the distance is 131mm * 49.5mm11. The finished product passed the function test and stability test Module interface:1. VCC: connect the positive pole of the 12V2 power supply. GND: connect to the negative pole of the 12V3 power supply. IN1-IN8: signal trigger terminal, effective low level Relay output terminal: there are 12-wire interface all interfaces can be directly connected to bring which is easy for users to use1. NO1--NO8: Relay is normally open interface, the relay is suspended before closing, and shorted to COM after closing2. COM1--COM8 common interface relay3. NC1--NC8: The relay is normally closed interface, the relay is short-connected with COM before it is closed, and it is suspended after it is closed
