Description

Long-Range Remote Controlled Switch 8-Channel with General Purpose SPDT Relays

This 8-Channel general purpose relay board is controlled from a programmable remote control Key Fob.  Available with 5 or 10-Amp SPDT relays (configured during purchase).  Built on ProXR, our Key Fob controllers are capable of controlling relays in a wide variety of ways.  Configure Key Fob buttons to toggle a relay, turn a relay on or off, Flash a relay, activate a relay for a period of time, and more.  The KFX series Key Fob controllers are unique in the industry because they provide tremendous relay control functionality.  This controller is equipped with general purpose relays, ideal for small motors, lights, and other automation applications.  KFX series controllers are available with an industry leading 750 or 1,000 foot range remote controls, configured during purchase.  Configure the KFX Key Fob receiver with your computer.  Once configured, a computer is no-longer required.  We can also custom pre-configure Key Fob controllers for you so they are ready for installation upon receipt.  Pair up to 40 remotes with a single Key Fob relay controller with complete security encryption.  Every remote will control the relays in the same way.  Operates on 12VDC.  Power supply, Key Fob remote controls, and other accessories sold separately.

About Key Fob Relays

Our 2nd generation Key Fob Series controllers allow users to control relays from a hand-held remote up to 750 feet away! Configure buttons to toggle relays, turn relays on and off, activate timers and control relay flashers. Integrated security features prevent unauthorized operation while maintaining easy configuration. Pair up to 40 different Key Fob remotes to a single controller.

How it Works

The Key Fob series controllers include a custom designed KFX Receiver to receive Key Fob signals and send pre-programmed data to the relay controller. When a button is pressed on the Key Fob, the KFX Receiver will send up to 9 bytes of data to the relay controller.

The KFX Receiver can be removed from the relay controller and connected to a computer for easy configuration. The KFX Receiver can be configured for button press and button release events. Use our free Base Station software to change the settings inside the KFX Receiver for controlling relays in different ways, such as relay timers, toggle commands, relay on/off and relay flashers.

The KFX Receiver can be configured for button press and button release events. If you intend to use smaller key fobs with less than 8 buttons, it is possible to use the extra KFX memory to send more than 9 bytes when buttons are pressed and released.

Additional Information

With a single KFX receiver module, users may associate up to 40 key fobs, including 1, 2, 3, 4, 5 and 8-Button remotes. KFX modules reach working distances of up to 750 feet, with superior responsiveness over previous generations of Key Fob receivers. 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. Put simply, every remote does exactly the same thing when paired with the same KFX Receiver.

Key Fob Configuration

The KFX Receiver Module is configured using our Base Station Software, and must be plugged into the ZIGMO 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.

Note: We do advise that if you are pairing numerous key fobs to a given KFX receiver module that the button number on each Key Fob is the same for all key fobs, however, this is not absolutely required, but it may make using the KFX easier.

10-Amp SPDT Relay Option

This controller is available with a 10-Amp relay option, allowing control of higher-power loads up to an absolute maximum of 240VAC at 10 Amps. Ideal for general purpose switching applications, this relays is focused on power-switching, and should never be used for low-power signals due to a higher On resistance of up to 150 Ohms when relay contacts are new (contact resistance drops to less than 1 Ohm after break-in period). The 10-Amp relay is of the SPDT variety, which provides Common (C), Normally Open (NO), and Normally Closed (NC) connections. Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated.  All connections are made via screw terminals, capable of accepting up to 12 AWG wire.

5-Amp SPDT Relay Option

This controller is available with a 5-Amp relay option, allowing control of higher-power loads up to an absolute maximum of 240VAC at 5 Amps. Ideal for general purpose switching applications, this relays is focused on power-switching, and should never be used for low-power signals due to a higher On resistance of up to 150 Ohms when relay contacts are new (contact resistance drops to less than 1 Ohm after break-in period). The 5-Amp relay is of the SPDT variety, which provides Common (C), Normally Open (NO), and Normally Closed (NC) connections. Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated.  All connections are made via screw terminals, capable of accepting up to 12 AWG wire.

KFX Pre-ProgrammingChange

By default each button will momentarily activate the relay. We can customize the output of the KFX module to suit your application preventing the need to purchase a USB Configuration Adapter and customizing it yourself. Simply add this item to your cart and tell us how you would like the KFX to act using the Order Notes during Checkout.

Would you like a power supply?Change

NCD Controllers Need Power. Standard NCD Power Supplies use a 2.1mm Barrel Connector with 12VDC (center positive) rated at 1.25 Amps (minimum).

KFX Recommended AccessoriesChange

KFX controllers need accessories, here you can choose the most popular accessories. Please note the USB Configuration Adapter is used to configure the KFX communications module. You only need one of these, but it should be considered a core requirement of owning the KFX Key Fob communications module.

Do you need Induction Suppression Capacitors?Change

Induction Suppression Capacitors are essential for managing inductive loads such as Motors, Solenoids, and other Electronic Devices that implement a collapsible magnetic field.  These capacitors will reduce the chances of Electromagnetic Interference with our controller and prolong the operational life of relays.

We Customize Just for You!!

NCD offers many custom IoT electronic design services to help tailor our product to your exact needs.  Whether you are looking for custom firmware, circuit board modifications, metal enclosures, or industrial color printing, we can help you with a wide variety of design services.

Custom IoT Electronic Design Services Process

Most of our users purchase off-the-shelf hardware for initial testing.  Once everything is working, they contact us to build a custom solution which may include specialized changes to the board, firmware, connectors, etc.  Custom boards have many advantages such as reduced wiring, easy installation, small size, less power consumption, and in some cases, an overall reduction in product cost.  Custom IoT Electronic Design Services will have your company name and logo on the board as well as the enclosure.

Customized IoT Electronics

NCD engineers can help build a customized solution for your particular application based on the designs you see on our website.  We can combine devices onto a single board, change the shape, or even some of the components to meet your exact needs.  We also provide turn-key metal enclosures with powder coating and full-color printing on the top side starting at just $500 for setup!  We have more than 20 years of experience in electronics design and manufacturing.  All of our products are designed and manufactured in the USA, so we are here to support the products we make.  We only ask that our customers prototype their needs using our existing products before we customize.

Customization Guidelines

  • Custom designs should be based on our existing product because we can’t build rockets or electric cars over here!
  • We do not provide customization services if it involves the introduction of a new or untested technology.
  • Custom engineering fees depend on your requirements, so please contact us for a quote!
  • We maintain ownership of all designs, including our customized designs as they are based on our existing Design.
  • We will only ship the customized product to you or your authorized agents.
  • We have an NDA available if needed.
  • The turn-around time is about 2-3 weeks.
  • We specialize in low-volume designs, no quantity is too small!
  • We have the ability to scale to large volumes as needed.

Getting Started with Product Customization

All you have to do is contact us and we will walk you through the process from beginning to end, based on your individual needs.  Some people are surprised at how fast we finish CAD design (usually a few hours), but keep in mind, we still have to build your design, which takes considerably more time.  When we customize product, here are the general services we provide:

  • We design the circuit board.
  • We communicate with our customers throughout the customization and manufacturing process.
  • We manufacture surface mount stencils and circuit boards.
  • We program our pick and place machines to build your boards.
  • We build a working sample and run it through our wave solder machine.
  • We test your custom IoT solution.
  • Once the design is finalized it won’t be possible to make changes during production (changes cost money and require us to repeat the above processes)
  • Once it meets all your requirements, we will start production as needed.
  • We work with our metal fabricators to design a metal enclosure if required.
  • You work with our artist to print the top side of the enclosure in full color with your company logo if required.
