Expansion Board 32-Channel 10-Amp
XR3210$551.00
XR Expansion Board
The XR3210 Expansion adds 32 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.

ProXR Expansion Board
This Expansion Board plugs into the XR Expansion Port on any ProXR Board to add more relays. Expansion boards can be daisy chained together to add the relays needed.
Add Relays as Your Needs Grow
The expansion board is compatible with the ProXR and Taralist Time Activated Relay boards. The ProXR and Taralist boards are fitted with an XR Expansion Port where you can add expansion boards. Expansion boards can be added until you reach 256 total relays. As you continue to chain expansion boards onto an XR expansion port, the total number of available relay banks will increase. Add expansion boards as needed in the future, whenever you require more relays simply order another expansion board.Linking XR Expansion Boards Together
XR Expansion Boards consist of a XR Input and XR Output Connector. Simply connect the XR Output of your ProXR Board 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 expansion board. Mix and Match different relay types as your application requires. A 6″ expansion cable is included with this expansion board.Will Not Operate Independently
This Expansion Board gets it's commands from the main ProXR or Taralist board and will not operate independently. This board MUST be plugged into a ProXR or Taralist board to operate and will not function on it's own.SPDT Relay Installed
This device has SPDT relays installed. SPDT Single Pole Double Throw Relays have three connections - Common, Normally Open, and Normally Closed. When the relay is off, the common is connected to the normally closed connection of the relay. When the relay coil is energized, the Common swings to the Normally Open Connection of the Relay. You can wire the device you are switching to either the Normally Open or the Normally Closed position using screw terminal connections. The maximum guage wire the terminal can handle is 14 ga but we have used up to 12 ga solid core for several applications with no issues.
Mix & Match
Expansion boards do not need to be the same relay amperage as the main board or other expansion boards. Mix &anp; match expansion board to get the exact amperage for your switching needs.Essential Power Requirements
This and all expansion boards require 12 VDC to operate. We offer a wall-wart type power supply at checkout if you need to plug this into a 110 wall outlet. Applying Good clean power to the board is essential for the operation of the board. Without good steady clean power from a regulated power supply the board simply will not function correctly. The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated power supply and it plugs into the barrel connector on the board. The output connector is a 2.1mm I.D. x 5.5mm O.D. x 9.5mm Female R/A barrel connector. We also carry an international power supply with interchangeable adapters for international customers.

Maximum Relay Rating Notes
ProXR is capable of expanding to an absolute maximum of 256 Relays. In some cases, it may not be possible to control all 256 relays, particularly in applications where high noise levels may be involved. Experimentation may be required, as it is not possible for us to guarantee all users will be able to utilize all 256 relays in every application. Noise tends to accumulate when several expansions are connected together. For best results, the XR expansion cables must be as short as possible.This Board is RoHS Compliant
This board is led free and RoHS Compliant. If your requirements are for RoHS compliant parts this board is manufactured with RoHS compliant led free parts and solder.
2-Million Cycles
XR Expansion Boards are designed for long life just as the ProXR boards, you should expect to get years of service from expansion board and literally 2-million cycles from the relays on board. With a 5-year warranty and a money back guarantee add more relay anytime the need arises! 5-Year Warranty/Money Back Guarantee
ProXR Lite series controllers are guaranteed against manufacturing and functionality defects for a full 5 years! Not to mention a 30-day money back guarantee! If for any reason you are not happy with a relay purchased from Relay Pros, simply return it within 30 days and we will give you your money back! Controllers that are damaged by our customers will not of course be warranted under any circumstances.Relay Expansion Videos
Power Supply Available
The PWR12 is regulated power supply providing clean power necessary for
the performance of these boards. The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated
power supply and it plugs into the barrel connector on the board. The output connector is a 2.1mm I.D. x 5.5mm
O.D. x 9.5mm R/A barrel connector.

Induction Suppression
Controlling
an inductive load using our relay controllers requires the use of induction suppression capacitors. The purpose of this capacitor
is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay. Without this capacitor,
the lifespan of the relay will be greatly reduced. Induction can be so severe that it electrically interferes with the microprocessor
logic of our controllers, causing relay banks to shut themselves down unexpectedly.
