Product description
8-channel relay board for Raspberry Pi that enables control of external loads such as lighting, motors, pumps, and other electrical devices via GPIO. The board connects directly to the Raspberry Pi through the 40-pin header and is suitable for automation solutions, smart home systems, test setups, and industrial prototypes.
The relays are galvanically isolated with optocouplers to reduce interference from high-voltage circuits and improve system robustness. Status indicators show the state of each relay, and screw terminals simplify connection of external circuits. The board can also be controlled via external controllers or PLC through dedicated control interfaces, and can be mounted on a DIN rail using the included bracket.
