DESCRIPTION
  • Maximum load: AC 125V/20A. DC 14V/20A; 
  • Using SMD optocoupler isolation. driving ability. stable performance; trigger current 5mA; 
  • Module voltage: 5V.  
  • The module can be set to high or low triggered by jumper; 
  • Fault-tolerant system. even if the control line is broken. the relay will not operate; 
  • Power indicator (green). relay status indicator (red) 
  • User friendly interface design. All interfaces can be connected directly via terminal wiring leads. very convenient 
  • module size: 50mm * 26mm * 18.5mm (L * W * H) 
  • has four mounting bolts holes. hole 3.1mm. 44.5mm * 20.5mm pitch 

 

Interface: 
  • DC +: positive DC power supply (voltage required by the relay.5 V)
  • DC-: negative DC power connection 
  • VREF: Ground electricode ; Connect to cathode of the controller board supply when set it to high; Connect to anode of the controller board supply when set it to high
  • CH1: Relay controller interface

     

    Relay outputs: 
    • NO1: normally open relay interface. the relay before the vacant after the pull shorted with COM 
    • COM1: Common Interface Relays 
    • NC1: normally closed relay interface, relay short connect with COM. after the pull-vacant 

     

    High and low level trigger selection ends: 
    • When jumper short circuit with LOW is low lever trigger; 
    • When jumper short circuit with high is high lever trigger.
