Description

ProXR Relay Expansion Board with 32-Channel DPDT Relays

This Relay Expansion Controller includes 32 on-board DPDT relays, capable of switching 1, 3, or 5-Amps of current, depending on the variant chosen.  This relay expansion controller is designed to plug into our ProXR series industrial relay controllers, and includes the required XR Relay Expansion Controller cable.  On-Board status LEDs indicate the on/off status of each relay.  This expansion controller 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.

New Version Shipping as Available

Beginning Late 2020, we’ve made some updates to this product to make it better with increased component count while maintaining the same functionality and footprint.  The New Rev G2 Series adds a better power supply circuit to improve noise immunity while providing increased power availability.  We also improved the relay drive circuit to better handle inductive loads and changed the color of the circuit board to Black.  We updated branding to Qatalytic.io with updated logos.

This is the same product you have been buying for years, but now with improved electronics and while maintaining the same footprint as the original design.  Most importantly, this is now a Legacy product, which means it will never go obsolete as long as critical parts are still available to us.  Built with our new high-speed pick and place assembly line, we can complete the surface mount assembly process at a rate of several thousand units per day with the potential to scale to any volume you could imagine, so you never need to worry about supply quantities or supply chain problems.

Notice: Some orders may receive the original version.  The updated version will begin shipping as original stock is depleted and new stock becomes available. 

Updated Features

  • Updated Logos and Branding, Changed PCB Color to Black
  • Improved Relay Drive Circuit for Greater Noise Immunity
  • Improved Power Supply Circuit using a Switcher Regulator for Lower Heat and Higher Power
  • Ferrite Beads Added to Better Separate Logic and Drive Circuits from Noise
  • Migrated to Commonly Available LEDs to Address Supply Chain Limitations
  • 99% Identical Shape – Only Slight Changes to Connector Positioning for Better Fit and Finish
  • Now Built by our High-Speed Pick and Place Machine for High-Volume Applications
  • Legacy Status Product – Will Not Become Obsolete

ProXR Expandability

ProXR Controllers were built with relay expansion in mind. Easily add different types of relays for high-power, signal, general purpose, or solid-state switching.  The XR Expansion Port allows you to also add expansion boards and control up to 256 relays.

Above: A 4-channel ProXR Series Controller (bottom) shown with an 8-channel expansion board attached.
Simply chain the XR Expansion Modules, one after another, to add additional relays to any ProXR board up to 256 relays.

XR Expansion Port

XR Relay Expansion Controllers add a large variety of relay switching capabilities to an existing Qatalytic ProXR series controller.

The XR Expansion Port is used to add banks of external relays to a ProXR Controller equipped with a XR Expansion port.  As we continue to develop new devices, a modular architecture will be implemented, offering the greatest amount of user flexibility.

Controlling XR Expansion Banks

FXR Expansion Boards have no on-board brains. They are entirely reliant on the brains of a “master” ProXR device.  The XR Expansion Modules have many possibilities:

  • Adds up to 256 Relays to a ProXR Series Controllers
  • Mix and Match Relay Types to Suite your Application Needs
  • Choose Between Mechanical and Solid-State Relay Types
  • Choose DPDT Relays for Signal Switching Applications

Linking XR Expansion Boards Together

XR Expansion Controllers consist of a XR Input and XR Output Connector.  Simply connect the XR Output of your ProXR Controller to the XR Input located on the relay expansion board.  Chaining more relays is easy.   Simply connect the XR Output of your ProXR expansion board to the XR Input of your next relay expansion.  Mix and Match different relay types as your application requires.

We always include a 6″ expansion cable with your expansion board.  We can provide longer cables if needed, but it’s important to keep the cabling as short as possible.  Not all users will be able to expand to 256 total relays, as it all depends on the installation, the amount of electrical interference, and the overall cable length.  For best compatibility, the total length of the ProXR controller and all of the expansions and cabling should not exceed 1 or 2 meters.
