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. 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.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.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.DPDT Relays Installed
This board has DPDT relays installed. A single DPDT relay is made up of 2 SPDT switches. Each relay acts as two switches that are activated at the same time. This allows two independent signals to be switched at one time. In effect, there are two independent switches on a single DPDT relay - they will always switch together.
There are two connectors with Normally Open, Normally Closed and Common for each relay allowing two separate connections. The picture above shows the 4-channel connectors. The diagram to the right shows the how the arms of the common connector swing from the Normally Closed to the Normally Open positions when energized. Wiring to either the NO or NC can produce your desired results. 2-Million Cycles
ProXR series controllers are designed for long life, you should expect to get years of service from your controller and literally 2-million cycles from the relays on board. With a 5-year warranty and a money back guarantee you have nothing to loose! Place your order now, while everything is in front of you.Essential Power Requirements
Applying Good clean power to the board is essential for the operation of the board. Not only for the switching of the relays but the firmware that processes the commands. Without good steady clean power from a regulated power supply the board simply will not function correctly. All boards on the site require 12 VDC power. 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.

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.
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.Shipping
The boards sold are brand new units shipped from our office conveniently located in Missouri. These boards are completely tested before they are released for shipping With so many boards on our site it is impossible to stock boards, please allow two to three days production time for your order to ship.

Reliable Power MeansReliable Switching
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. Learn More about
