1-Channel Relay Module with Low/High Level Triggering - EX1RMH

The board offers the possibility of individual control of one electromagnetic switch with load circuits of 10A at 250V. The board is powered by supplying 5V and GND to terminals – DC+ and DC-. The control mode of the relay board is selected via a jumper – high or low level. When the jumper is set to position H – high level, a 5V signal is required on the control pin IN to switch the relay. When the jumper is set to position L – low level, a low level (GND) is required on the control pin IN to switch the relay. All three relay outputs – normally closed, common, and normally open, marked as NC, COM, and NO – are available on the output terminal. An indicator LED is present, showing whether the relay is activated.
