- Galvanic isolation between the control circuit (5 V) and load circuit
- Load side, up to 250 V AC / 10 A or 125 V AC / 15 A
- Electromechanical relay with changeover contact (NO/NC/COM)
- Two LEDs for power supply and switching status
- Screw terminals and plug connection on the control side
Product description
This relay module switches high-voltage or high-current loads via a digital output pin of a microcontroller. The galvanic isolation between the control side and load side protects the controller from feedback and makes it possible to connect completely independent circuits.
The relay energizes when the control input is high and connects the COM terminal to the NO contact (normally open). If the control signal is absent, COM is connected to the NC contact (normally closed). The coil requires 5 V and approximately 71.4 mA of current. On the load side, the contact switches up to 250 V AC at a maximum of 10 A or up to 125 V AC at up to 15 A, corresponding to a switching capacity of 2500 VA in AC operation.
Two LEDs indicate the operating status: one signals the module's power supply, while the other lights up when the relay energizes. This allows you to check whether the module is active and responding without additional measuring equipment. Typical applications include controlling lamps, pumps, valves, or motors via Arduino and similar boards when the load to be switched requires a higher voltage or greater current than the controller can supply directly.
The module is supplied with 5 V and controlled via a digital pin. A separate voltage source must be provided to power the load side. The control input level must not exceed 5 V; systems with 3.3 V logic require a level shifter.
Safety notice
The load side of this module is not intended for operation on household electrical installations. The module is intended exclusively for building prototypes and for testing and development purposes. Work on or immediately adjacent to mains-voltage circuits must be carried out by a qualified electrician; a qualified electrician must be consulted before commissioning with mains voltage.
