Description

  • The module uses a genuine quality relay, normally open interfaces , Maximum load: AC 250V/10A, DC 30V/10A.

  • Using SMD optocoupler isolation, strong driving capability, stable performance; trigger current 5mA.

  • Fault-tolerant design, even if the control line is broken, the relay will not move.

  • All interfaces are available through a direct connection terminal leads.

  • The Module can be set by a jumper to a high or low trigger.

Technical Details

  • Module description:
    1.The module Operating voltage 5V;
    2.Fault-tolerant design, even if the control line is broken, the relay will not operate;
    3.The power indicator (green), the relay status indicator (red);
    4.Module size: 42mm*34.4mm*18.5mm (L*W*H).

    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¡± connect with ¡°COM¡±
    3. High or Low Level Trigger Select
    Jumper connect with L, Low Level Trigger
    Jumper connect with H, High Level Trigger
