The controller will accept a voltage range of 7.5 to 25VDC. However, if you plan to implement a door-activation device, your supply voltage must match the coil voltage of the activation relay. Our field wiring terminal board (FWTB) includes an activation relay with a coil voltage of 12VDC. Therefore, 12VDC is recommended if you use the FWTB.
