Control up to 256 Relays with any ProXR Controller
XR Expansion
XR Expansion Boards will allow you to add up to a total of 256 relays using the XR Port on your controller. These Expansion Boards are only compatible with ProXR series boards and are not able to work on their own. They get their instructions from the main controller.

Solid State XR Expansion
Mechanical Relays have a good home in low-cost control applications. But for some users, only solid state switching will do. Solid State Relays are ideal for users who require long term reliability, silent operation, or high induction tolerance. Many inductive control applications require a solid state relay. Inductive loads such as Motors, Valves, Pumps, Solenoids, and Large Transformers (including Fluorescent Lighting) benefit from the use of solid state relays because they reduce the chances of the inductive load interfering with the logic of the relay controller.
XR Expansion Modules
XR Expansion Boards have no on-board brains. They are entirely reliant on the brains of a "master" device. A master device is an NCD controller with an XR expansion port and a microprocessor of some kind. Some master devices are wireless, and some master devices have digital I/O and analog to digital conversion capabilities. Some master devices also have on-board relays. The main purpose of the XR port is to add relays to the main controller. When you run out of relays, simply plug in an XR expansion controller that is equipped with the kind of relays you need. All XR Expansion modules are compatible with each other so if you want to add different types of relays you can. For controllers that are equipped with an XR Expansion port (and are suitable master devices for XR Series Expansion Controllers) simply look for PROXR in the part number.
