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.

    WHAT'S IN THE PACKAGE
    • 1 x optocoupler isolation relay module
