Relay Electromechanical, Optocoupler Module Board，5V/12V/24V High & Low Trigger for Arduino (24V)

√[powerful driving force]: The Relay module uses chip optocoupler isolation, which has powerful driving capability and stable performance. The trigger current is 5mA. √[Jumper Setting]: Relay Electromechanical is 1 Each path of the Channel Relay Module can be triggered by a high level or low level by a jumper setting. √[Friendly design]: Low level trigger relay module power indicator (green) and one-way relay status indicator (red). User-friendly interface design, all interfaces can be directly connected through the terminal leads. Four fixing bolt holes are provided. √[Alternative]: The Optocoupler Relay Module Board adopts a fault-tolerant design, and the relay will not move even if the control line is disconnected. √[Select a variety of]: Relay Electromechanical is High & Low Trigger Module can work at 5V, 12V and 24V.
