Key Fob Remote 4-Channel 10-Amp

The Key Fob Interface

Easy Key Fob Control

If your application requires you to control a relay from a wireless remote control, then our Key Fob Relay boards will offer the most powerful solution available on the market today.  Not to be confused with single function low-cost solutions, our Key Fob Relay boards are years ahead!  Configure your Key Fob Buttons to control relays in just about any way you can think of! 

Key Fob Functions

A button push on the key fob can be set for a simple on/off function and so much more!  Most users use the key fob as a toggle or momentary setting.  The toggle command is a push-on push-off command push a button and the relay will remain energized until the button is pushed again to turn it off.  A push and release command can be set for a momentary command, when the button is pushed the relay energizes and when you release the button the relay turns off.  Either of these commands will be set before your board ships.  More complicated commands can be configured as well!  Relay groupings if you want one button to control more than one relay.  Time delays can be set where one button push can control the relay for a prediturmined time and the relay will turn off automatically!

Easy Configuration

This board is equipped with a KFX Module.  The KFX communications module adds key fob capabilities to the board.  Configuring the board is done using Base Station Sofware, a free download.  Point and click configuration using a numerical command set get's the action your looking for for each button push.  We'll even do the setup for you, choose toggle or momentary at checkout above!

Common Commands

Here's a brief list of some of the more common commands used when a button is pushed on the key fob.

• Toggle and Momentary Commands
• Turn Off All Relays Then Turn On a Specific Relay
• Relay Timers: Relay Energized for a Specific Time
• Relay Pulse Commands
• Relay Grouping: Controlling Multiple Relays Together
• Relay Flashing Commands

Key Fob Range

The rated range of the MS series Key Fobs is 750 feet (228 meters). The MS 8-Button Key Fob with an external antenna is rated at 1,000 feet (304 meters).  Key Fob range can depend on many factors.  The maximum ratings are achieved in an outdoor environment with clear line-of-sight and minimal radio interference (in the country). 

Up to 40 Key Fobs

With a single KFX receiver module, users may associate up to 40 key fobs, including 1, 2, 4 and 8-Buttons (available at checkout).  Every Key Fob paired with a KFX Receiver will perform the exact same function as another Key Fob paired with the same KFX Receiver.  It is not possible for each remote to be separately identified and generate different data for.  Put simply, every remote does exactly the same thing when paired with the same KFX Receiver.

ZigMo Configuration Kit

The KFX Receiver Module is configured using Base Station Software (a free download), and must be plugged into the ZIGMO Configuration Board only during configuration.  Only one ZIGMO is needed regardless of the number of KFX Receivers you intend to use.  The ZIGMO acts as an interface between your computer and the KFX Receiver, allowing you to define the Baud Rate, and Data Bytes that are transmitted for each Key Fob button Press.  The ZIGMO is included with the KFX Integration Kit and available at checkout.  Key Fob Configuration

Who’s Qualified to Use the Key Fob Series?

Some computer skills required.  The Key Fob Relays do not require programming, simply configure the module with the included Base Station Software.  While programming is not required and simple functions can be done rather easily with basic computer skills, complex events can be configured which will require some understanding and patience.

Key Fob Board Features

Key Fob Relay

In this tab we'll take a look at the board design itself.  The Key Fob ProXR Lite series controllers are machine manufactured for a highly accurate and reliable design.  Fully tested before they leave the production facility each Key Fob Relay 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

This board is a ProXR Lite board and cannot be expanded.  There is also Analog to Digital inputs on the board that will not be used with the Key Fob configuration.

Full ProXR Enhanced Firmware Installed

This board has ProXR Firmware installed that responds to the full ProXR Command Set - it's just not expandable.  These commands can be used to configure each button the the key fob to correspond to a relay on the board.  Press and release commands can be configured allowing for a toggle (push a button to turn on the relay, push again to turn off) or momentary (push a button to turn on a relay, release a button to turn off) actions.  More complex actions such as delays can be configured as well.

Powering The Board

This board as well as all boards on the site require 12 VDC power.  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.  More that one troubleshooting question has turned out to be from someone who says they are using a power supply that they had "just laying around" and it was not sufficient enough to provide the power needed to operate the board.  We also carry an international power supply with interchangeable adapters for international customers.

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

Key Fob Relay boards 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.

AD8 Analog Input Usage Notice

Analog Inputs should not have a voltage present when powered down.  Use a 220 Ohm current limiting resistor on each input to prevent damage to the controller if voltage will be present on the analog input when this controller is powered down.  Do not exceed 0 to 5VDC on any analog input or the on-board CPU will be damaged.  Most analog inputs include a 10K Pull Up/Down resistor to help keep the inputs quiet when not in use.  This 10K resistor may slightly bias the readings of some sensors.
