1-channel relay module with optoisolation and configurable triggering is a versatile solution for load control in microcontroller projects. Thanks to its compact design and stable connectors, it is suitable for automation and prototyping applications.
The universal module with a single SPDT relay allows independent control of a load with a maximum current of 10 A and voltage up to 250 V AC or 30 V DC. It is operated via a digital signal from a microcontroller or development board. The built-in optoisolation separates the input circuit from the output, protecting control electronics from interference and voltage spikes.
The module operates at 5 V and features configurable trigger mode – the relay can be activated by either a LOW or HIGH state using a jumper ("L" or "H" positions). LED indicators signal power presence and relay activation. Wires are connected via ARK screw terminals, ensuring secure connections.
