New Devices Ready to Ship

Newest Devices Latest Technology

At NCD we offer the largest selection of relays in the world!  If you're looking for the newest devices and the latest in relay control you've come to the right place.   We have started 2010 out with our biggest release yet - The Reactor Series Relay Control and Key Fob Control.  No programming required for this series of controller and no computer required for them to perform their duty!  A simple interface lets you configure the controller connect your sensors and you're ready to go.  Put the power of computer controlled switching in you hand with our new Key Fob series controllers.  Turn on relays or over ride the existing configuration with a key fob!  We've listened to your requests and we are introducing a line of sensors that we have tested and work with our controllers!

In 2009 we introduced our biggest wireless technology yet with our Mesh Networking line of wireless controllers!  And with our newly released "ZSCAN" Series Mirror Modules we've gone beyond computer control to give you the ability to control relays without the use of the computer!  2009 has also seen the release of a complete line of Solid State Relays, XSC Long Range Wireless Relays for long range wireless control and a complete line of Contact Closure Input Boards for reading motion detectors, glass breakage detectors, window/door open detectors, light switches, and other kinds of devices with a contact closure output.

Our ZigBee, WiFi and Bluetooth devices are all shipping now!  Our line of Fiber Optic Relays began shipping in 2008 and has proven to be a popular way to collect data and control high-power devices with minimal EMI, which can adversely affect computers.  

A beta version of went online October 1st. is a new and exciting way to control relays from anywhere in the world!  Now fully functioning, will let you control lights, monitor temperature, read motion detectors, capture images, and generate emergency alert notifications...from anywhere in the world - all through your browser with no programming!  Internet data collection is finally available to you even if you have never done it before.

Control relays like you never thought possible with National Control Devices!

MirX Relay Pair Series Controllers

No Computers, No Configuration, Works Right out of the Box

Every MirX controller is equipped with contact closure inputs and outputs. The inputs on one controller activate the relays on the remote device using wireless communications. The "X" in MirX refers to the crossover. Since both devices are equipped with contact closure inputs and relays, each device targets and controls the remote device.

MirX devices are only sold as a permanently married pair, pricing shown on our web site indicates pricing for the pair of controllers. Contact Closure Inputs may only be connected to switches, buttons, or sensors with Contact Closure capability. Not suitable for use in voltage detection applications.

Our MirX Relays relays are always sold in married pairs and feature SPDT & SPST relays and are available with the same number of contact closure inputs/outputs as there are relays installed on the board.  The MirX Series Relay Controllers are ready to go to work immediately out of the box. No Computers, No Configuration, Just Simple, Reliable 802.15.4 Wireless Communications between two devices that permanently work together as a married pair.

Reactor Relay Controllers

Analog Inputs Trigger Relays          Now Shipping

NCD Engineers are currently finalizing the development of a completely new generation relay controller.  The Reactor Relay Series controllers represent the worlds first relay controller capable of making its own intelligent decisions based on user input.  Unlike previous generations, the Reactor Relay Series controllers are configured using our custom Reactor Configuration Utility.  Once configured, the controller works without a computer connected, allowing analog inputs to trigger relays according to the configuration.

The Reactor Relay was developed to address the needs of customers who need a controller capable of making intelligent decisions without a computer.  Live Reactor Relays are configured wirelessly.  Once configured, the Reactor will work on its own.  At any time, a remote computer may read analog inputs and take control of the relays.  The remote computer can later return control back to the Reactor logic.

8 Channel Reactor Relay with Break-Away Tabs
Up to 8 timers and 4 rotations can be configured to control up to 8 relays based on 8 separate analog inputs.  Programmable Trigger Points can Trigger Timers and Rotation Counters when Analog inputs reach preconfigured levels.

Users may load and save reactor settings into individual files.

The new Reactor Relay Series features our new surface mount LED lights.  These lights are smaller and brighter than previous generation lights for making relay status easier to read at a glance.  The Reactor Relays will also feature a new board design with Break-Away Tabs.  With the Tabs on, the board will fit into an enclosure.  If your project requires a smaller profile without an enclosure, simply snap off the tabs on each side for a smaller board.

Interfaces will include USB, ZigBee Wireless, XSC Long Range Wireless and ZB Mesh Networking.  All interfaces will be available in 1Channel, 2 Channel, 4 Channel and 8 channel relays.

Key Fob Control

Control Relay with a Key Ring Fob         Now Shipping

We have completed the testing phase on our new line of keychain size Key Fob Relay Control.  Users will be able to control relays with the touch of a button you hold in your hand!  Touch a button and a command to will be sent to a Reactor Relay Series board that has a key fob chip installed to activate a relay.  The Key Fob Relay will be compatible with relays with up to 8 channels.  Each Key Fob button can be programmed to control up to 8 relays in any number of ways.  The Key Fob Relay will also be able to provide a manual override to the Reactor Series Relay Boards.  We expect these to be available in January 2010. 
    Key Fob Relay Applications Include
  • Garage Door Opening/Closing
  • Override Existing Programming
  • Lighting Applications
  • Pump Activation
  • Anywhere You Need Quick On-Location Switching

4 Channel Key Fob Relay Control
Put the Power of Computer Controlled Switching in Your Hand
When used in conjunction with our Reactor Relay Series onboard timers, a relay can be activated by the Key Fob to turn on, such as opening a garage door.  The timer can then be set to automatically switch the relay again.  With the example of the garage door, the door would then automatically shut after a predetermined time.  This is just one simple example of the many uses that you can customize to meet your specific switching needs.
