AC-USB SPS Relay and 2 Sense Inputs

Controls a single pole switchover relay through a USB port and can sense Door Ajar with a Request to Open input. Specifically designed to work with Ringdale Access Control devices.


Controls a single pole switchover relay through a USB port. The device is specifically designed to work with Ringdale networked access control devices. It encrypts the communication between the controller and the USB relay board.

In addition, the device allows the sensing of a Door Ajar switch and a Request to Open Switch. The Door Ajar sensing assumes the switch to be normally closed and the door being ajar if the switch is open. The Request to Open senses a request if the connected switch is closed.

The device will only work with Ringdale Access Control Systems - Ringdale also supplies a General Purpose USB Relay for your own applications which does not require encrypted communication. For more information on the GP USB Relay click here

Note: When connected to a Ringdale Access Control Reader, this device should always be installed on the secure side of a building. The device is sealed and not customer serviceable.
