5V 12V 8 Channel Relay Module Shield With Optocoupler 8 Way Relay Board PIC AVR MCU DSP ARM 8-Channel Relays Module
8-way relay output module, relay output contact maximum 250V 10A. Input IN1, IN2, IN3, IN4, IN5, IN6, IN7, IN8 signal lines are active low. VCC, GND power input terminal, can relay a separate power supply relay power input of JD-VCC.
Features:
Using high-current relay , AC250V 10A DC30V 10A
Contact some independent wiring , safe and reliable
Standard interface , can be extended in a variety of development board
With fixed screw holes for easy installation
Suitable for a variety of platforms such as 51/AVR/MCU/ARM
Module description:
1. This module complies with international safety standards, and the control area and the load area have isolation slots;
2, the use of double-sided FR-4 circuit board design, high-end patch production;
3, using genuine relay control;
4, with relay action indication, the suction is bright, the disconnection is not bright;
5. When the signal input terminal has a low level signal, the common terminal and the normally open terminal will be turned on;
6, the relay can directly control various equipment and load;
7, there are 8 normally open and 8 normally closed contacts;
8. The blue KF301 terminal is more convenient to connect to the control line.
9, Module size: 138m * 56mm * 18.5mm (length * width * height), Net Weight: 120g
10, with 4 fixing bolt holes, hole 3.1mm, spacing 131mm*49.5mm
11, the finished product passed 100% functional test and stability test
Module interface:
1, VCC: connected to the positive pole of 12V power supply
2, GND: connect the negative pole of 12V power supply
3, IN1-IN8: signal trigger terminal, active low
Relay output: 12-line interface, all interfaces can be directly connected to facilitate user access
1, NO1--NO8: relay normally open interface, the relay is suspended before the suction, short-circuit with COM after the suction
2, COM1--COM8 relay common interface
3, NC1--NC8: relay normally closed interface, short-circuit with COM before the pull-in of the relay, and float after the suction
