12V 10A 8 CH Channel OPTO COUPLER Relay Board Module

12V 8-Channel Relay Module Optocoupler Low Level Triger for Arduino Precise

Module Description:

 1, the module complies with international safety standards, the load control area and regional isolation tank;
2, using double-sided FR-4 circuit board design, high-end chip production process;
3, using loose music authentic relay control;
4, with the relay instructions, pull off, disconnect does not shine;
5, the signal input has a low signal, often beginning with a common terminal will be turned on;
6, the relay can control the various devices and the load;
7, 8 and 8 normally open normally closed contact;
8, blue KF301 terminals to the control line is more convenient.
9, Module size: 138m * 56mm * 18.5mm (L * W * H), Weight: 120g
10 with 4 fixing bolt holes, hole 3.1mm, pitch 131mm * 49.5mm
11, finished by 100% functional testing and stability testing

Features 

1.Using high-current relay, AC250V 10A DC30V 10A 
2.Contact some independent wiring, safe and reliable
3.Standard interface, can be extended in a variety of development board
4.With fixed screw holes for easy installation
5.Suitable for a variety of platforms such as 51/AVR/AVR/ARM

Module interface:

 1, VCC: 5V power supply connected to the positive
2, GND: 5V power supply connected to the negative
3, IN1-IN8: trigger signal, active low
Relay outputs: a 12-line interface, the interface can be directly connected to all leads, user-friendly
1, NO1 - NO8: normally open relay interfaces, relay before the vacant after the pull shorted with COM
2, COM1 - COM8 Relay Common Interface
3, NC1 - NC8: normally closed relay interface relay shorted with COM ago, after the pull-vacant

Usage: 

1, support all MCU control. 
2, industrial areas;
3, PLC control;
4, smart home control
