Optocoupler Relay Module with Selectable Trigger

Add relay switching to a compatible electronics project with a module available in multiple channel counts and supply voltages.

Choose the switching layout for your project

Selectable high- or low-level triggering gives you flexibility when matching the board to a control circuit. Normally open, common and normally closed output terminals provide the connection choices needed for an appropriate relay arrangement.

Product details: Optocoupler relay module in the selected one-, two-, four- or eight-channel configuration. Choose the exact 5V, 12V or 24V version shown and match its supply and load requirements to your circuit.
