XR Expansion Board
The XR810 Expansion adds 8 10-Amp relays to a ProXR Board. This relay expansion board is designed to plug into the ProXR series
relay boards, and includes the required XR Relay Expansion Controller cable. On-Board status LEDs indicate the on/off status of each
relay. This expansion board operates on 12 Volts DC, and may be powered by connecting two-wires to the on-board screw terminal connector,
or by plugging in power supply (sold separately) with a 2.1mm center positive barrel connector.
