For Arduino AVR 51 PIC 8 Channel Relay Module 24V with Optocoupler Isolation Relay Module Relay module

Description

Description:1. When there is a low-level signal at the signal input, the common terminal and the normal beginning will be connected.2. Relays can directly control all kinds of equipment and loads.3. There are 8 open and 8 closed contacts.4. Blue KF301 terminal connection control line is more convenient.5. Module size: 138m * 56mm * 18.5mm (length * width * height), net weight: 240g6. There are four fixed bolt holes with 3.1 mm spacing of 131 mm*49.5 mm.7. The finished product passes 100% functional test and stability test.Module interface:VCC: Connect 24V power supply positive poleGND: Connect negative pole of 24V power supplyIN1-IN8: Signal trigger, low level effectiveRelay 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 SuctionPackage Included:1 x 8 Channel 24V Relay ModuleHigh performance microcontroller for high stability, high reliability and low power consumption.Reverse power protection function, avoiding surge current shock.
