8 Channel Relay Module 24V with Optocoupler Isolation Relay Module Geekcreit for Arduino - products

Description: 1. The module meets the international security standards, and there are isolation grooves between the control area and the load area. 2. Adopt double-sided FR-4 circuit board design and high-end patch technology. 3. Use Songle genuine relay control; 4. With relay action instructions, suction and closure are bright, disconnection is not bright; 5. When there is a low-level signal at the signal input, the common terminal and the normal beginning will be connected. 6. Relays can directly control all kinds of equipment and loads. 7. There are 8 open and 8 closed contacts. 8. Blue KF301 terminal connection control line is more convenient. 9. Module size: 138m * 56mm * 18.5mm (length * width * height), net weight: 240g 10. There are four fixed bolt holes with 3.1 mm spacing of 131 mm*49.5 mm. 11. The finished product passes 100% functional test and stability test.

Module interface: VCC: Connect 24V power supply positive pole GND: Connect negative pole of 24V power supply IN1-IN8: Signal trigger, low level effective Relay Output: There are 24-wire interfaces, all of which can be directly connected to lead out, convenient for users to use. NO1-NO8: Relay usually opens interface. Relay is suspended before switching on and after switching on, COM1-COM8 relay public interface is short connected with COM. NC1-NC8: Normally Closed Interface of Relay, Short Connection with COM before Relay Suction, Suspension after Suction Package Included:
