This module is ideally suited to controlling multiple larger voltages with project. This is a 4 channel relay module which can be used to activate up to 250V AC and 30V DC. This allows you to build in device control, operating remote lights or triggering systems when the module is supplied with a signal. This signal can come from a range of sources including most standard microcontrollers.
The module has 4 LEDs that inform of the state of the module. A red power activation LED that lights when a signal is received on the IN pin. When a signal is received a audible click can be heard as the relay triggers, connecting the output pins.
