• User friendly interface design. All interfaces can be connected directly via terminal wiring leads.

Interface:

-Input

• VCC: Relay power supply +

• GND: Relay power supply -

• IN: Signal trigger input (High or Low Level Signal, select via jumper)

-Output

• NO: Relay normally open.

• COM: Relay Common Pin

• NC: Relay normally closed.

High or Low Level Trigger Select:

1. Use High Level Trigger

• When ¡°IN¡± input High Level Signal, the ¡°NO¡± connect with ¡±COM¡±

• When ¡°IN¡± input Low Level Signal, the ¡°NC¡± connect with ¡°COM¡±

2. Use Low Level Trigger

• When ¡°IN¡± input Low Level Signal, the ¡°NO¡± connect with ¡±COM¡±

• When ¡°IN¡± input High Level Signal, the ¡°NC Features:
  • 12V Relay Module: Working Voltage: DC 12V; Maximum Load: AC 250V/10A, DC 30V/10A; Trigger Current of Opto-Isolator: 5mA
  • Fault-Tolerant Design: Fault Tolerant Design, Even if the Control Line is Broken, the Relay will not Operate;All Interfaces of Relay can be Wired Out Through the Terminals Directly,Normally Open and Normally Closed
  • Optocoupler Isolation:1 Channel Relay Board use Optocoupler Isolation that has Strong Driving Ability and Stable Performance ,The Isolation Circuit Prevent Damages to I / O Port by Relay Switch Current
  • Jumper Design: The Relay Module has a Jumper That You Can Set Rather the Unit State Changes with High or Low Signal. Has Screw Terminals for Relay (NC,C,NO) and for Input; Coil +, Coil - and Trigger.
  • Wide Application: DC 12V Relay Module Works Well with ARM /PIC /AVR /MCU/Raspberry/CNC Machine/ PS4 etc.
