4-Channel 10-Amp Relay Board ProXR Lite

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.  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. 

The ProXR Lite Relay Board

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.

ProXR Command Set

The ProXR Firmware installed on the board has more commands and functionality than any other board on the market!  The list of commands and parameters this board is capable of is extensive!  Writing your own program can be done in just about any programming language so you can use what you are comfortable with!  Software is available for those who aren't programmers.  You can find the complete command set in the ProXR Quick Start Guide.

Base Station Software

Base Station Software was designed to help you learn the ProXR command set.  Explore ProXR features using it's Graphical User Interface.  Watch data bytes flow to and from the board, so you easily understand the command execution process.  There is no faster or easier way to learn how to automate than Base Station, as it was designed to work with the complete array of communication modules.  Base Station software supports every feature of this device - no other controller manufacturer even comes close to offering this type of software. 

Easy Software Development

Most of our customers write their own program for controlling these relays.  Since you can use almost any programming language, you can use one that is most familiar to you so you don't have to learn a new language.  These boards support the Serial Port Profile, meaning they will mount to the computer as a virtual com port. This makes it very easy to send commands to the board.  Not a programmer, check out N-Button!  Software that allows you to configure buttons to control relays and read the status of those relays without programming using point-and-click action.  Click Here for More

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

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 (0 being a dry contact)!  A/D inputs are ideal for reading the on/off status of switches, connect a switch between input and ground and software may then be used to monitor the contact closure status of the switch.  AD inputs can also be used for reading variable resistance signals, the board will then will return a value between 0-255.  Click the grey Data Sheets tab above and look for the AD8 Quick Start Guide to see the full AD command set.

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.

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.

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.

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. 

Induction Suppression

Perhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads can best be defined as anything with a magnetic coil, such as a motor, solenoid, or a transformer.  Controlling a inductive load using this relay board requires an induction suppression capacitor for each relay being used.  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 interferes with the logic of the board, causing relay banks to shut down unexpectedly.  For more information view our Induction Suppression Video.

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.
