Product Description
Product description:
1.This module conform international safety standard,the isolation groove between control areas and load area.
2.Using double-sided FR-4 circuit board design,high-end patch production process.
3.Using authentic relay control.
4.This relay has relay action instructions,pull on,disconnect off.
5.When the signal input terminal has a low-level signal,the common pin and the normally-open pin will conduct.
6.Relays can directly control a kind of equipment and loads.
7.Each relay has 8 normally open and 8 normally closed contact.Can be selected by jumper relay and TTL or ground.
8.Blue KF301 terminal connect the control line more convenient.
9.This product passed the 100% functional test and stability test.
10.VCC:conncet to Positive 12V power supply
11.GND:connect to negative 12V power supply
12.IN1-IN8:signal trigger,active low
13.Relay output:Has 12-wire interface,all interfaces can be directly connected to lead out,easy to use.
14.NO1--NO8:Relay normally open interface,before the relay suction the interface is unconnect, after suction the interface will short connect to COM.
15.COM1--COM8 relay public interface.
16.NC1--NC8: Relay normally closed interface,before the relay suction short connect to COM,after suction the interface will pull open.
