4-Channel 5-Amp Relay Board ~~Refurbished~~

Interface Options

Interfaces are not included with this board.  An interface is how you will communicate to the board.  This board is controlled by sending commands to the board through a computer (except for a key fob module which will send commands using a key fob).  Without one of the interfaces below there will be no way to communicate to the board.  Below are the interface options available.

Refurbished Boards

Refurbished boards have the most current firmware and face the same strict testing procedures that all our boards undergo.  This B-Stock or Refurbished board is a fully working board that may have slight scratches or blemishes that do not effect the operation of the board.  The board may be an overstock or returned from a customer.

Interface Options

This board may not have a communication Interface installed and you have the ability to select the interface you would like at checkout.  The interface must be selected of you will not be able to communicate to the board.

Limited Quantities

There are most likely limited quantities of this board available.  We do offer quantity pricing on our boards and can offer this if there is sufficient quantities available. 

ProXR Lite Relay

In this tab we'll take a look at the board design itself.  The ProXR Lite series controllers are machine manufactured for a highly accurate and reliable design.  Fully tested before they leave the production facility each ProXR Lite controller is ready to stand up to rigorous demands from heat, cold or vibration.  The best test of all is the numerous boards in the field from customers all over the world in all sorts of conditions.  Take it from us, these controllers will hold up!

Not Expandable

Unlike it's big brother, the ProXR Series, the ProXR Lite series controllers are NOT expandable.  The firmware still thinks 256 relays are available but the relay portion of the controller only responds to the first 1, 2, 4 or 8 relays in Bank 1.

Full ProXR Enhanced Firmware Installed

This board has ProXR Firmware installed that responds to the full ProXR Command Set - it's just not expandable.  The ProXR Firmware is the industry leading firmware for controlling relays with more commands and functionality than any other board on the market.  The list of commands and parameters this board is capable of is extensive.  ProXR Enhanced firmware has more commands, more functionality and better control than any other manufacturer!  For a detailed list of all the commands with descriptions see our ProXR Enhanced Command Set.

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.

Read Analog Sensors

We did NOT skip the Analog Input portion of the ProXR Lite.  All ProXR Lite controllers offer a 8-Channel 8/10-Bit Analog to Digital Converter in addition to relay control.  Read and control from 8 sensors per board from 0 to 5 volts!  A/D inputs are ideal for reading the on/off status of switches.  Simply position the Up/Down jumper in the UP Position and connect a switch between input and ground, software may then be used to monitor the contact closure status of your switch.  AD inputs can also be used for reading variable resistance signals.  Position of Up/Down jumper should also be in UP position for reading variable resistance signals. The board will then will return a value between 0-255.

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 over 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. 

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.

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.

Break-A-Way Tabs for a Smaller Design

The ProXR Lite relays have a great feature where space is a premium - Break-A-Way Tabs. The Break-A-Way Tabs allow most boards to fit in an optional undrilled plastic enclosure.  Snap off the Break-A-Way Tabs and you have a controller with a smaller profile when you need to fit in a tight space.

30-Day Warranty/Money Back Guarantee

ProXR Lite series controllers are guaranteed against manufacturing and functionality defects for a full 30 days!  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.  If you have any questions please feel free to call our office at 800-960-4287 or e-mail us at sales@relaypros.com.

ProXR Lite Is Here!

A more streamlined manufacturing process brings a more durable, reliable and better relay board to the market.  Here's a lists of great features:

User Friendly Board Design
