Low-level trigger relay interface module for compatible Arduino and microcontroller projects. Choose the board supply voltage and number of relay channels before ordering.
Package — 1 module
Each quantity of 1 includes one relay board in the selected voltage and channel configuration. The main photograph shows the available range, not a multi-board kit. Controller boards, wiring and power supplies are not included.
Select your configuration
- Board supply voltage: 5V, 12V or 24V DC
- Channels: 1, 2, 4, 6 or 8
- Low-level trigger control
- Screw-terminal relay outputs and status indicators
- Mounting holes for installation
Connections and compatibility
Connect a supply matching the selected module voltage. Relay outputs use common (COM), normally open (NO) and normally closed (NC) contacts. Control inputs are separate from the switched load connections.
The supply-voltage selection is not the control-signal voltage or a guaranteed load rating. Verify board markings, input logic, wiring and load requirements before use. Images illustrate channel layouts; relay voltage markings vary with the supplied model. Board dimensions vary by channel count.
