DPDT Relay

Relay Boards with DPDT Relays Installed

Double Pole Double Throw Relay

A DPDT Relay, Double Pole Double Throw Relay, has a single coil with two arms that move at the same time.  There are two completely separate SPDT switch mechanisms inside a DPDT relay.  A DPDT relay board is most commonly used for signal switching applications, but can be found in high power switching applications as well.

Wireless Relay with Analog to Digital Conversion Wireless Relay with UXP Expansion Port Wireless Relay with XR Expansion Port

Onboard analog to digital conversion is available on selected models of these controllers! This will allow you to:

  • Read light and temperature levels
  • Easily activate relays when A/D limits are reached
  • Detect audio levels in a room when connected to a microphone
  • Read switches, potentiometers, and analog joysticks
  • applications are limitless, and surprisingly easy to integrate
  • Available on select boards

UXP is a new standardized data port, specifically for the purpose of speaking to various expansion modules. If the controller you are considering is equipped with a UXP port, you can take advantage of extended commands to speak to our growing line of I/O expansion modules. UXP in the part number allows you to:

  • Add Contact Closure Inputs
  • Add Analog to Digital Inputs
  • Add Voltage Detectors
  • Digital Potentiometer Outputs
  • Available on select boards

Models with the ProXR suffix will feature the ProXR commend set. The ProXR series will allow you to:


NCD Component Library

Download NCD Component Library

By downloading the NCD Component Library you will receive over 40 samples from A/D Conversion to Duration and Pulse Timing and best of all it's FREE!! We want the user to be able to experiment with all the different samples available so as of right now the samples cannot be downloaded individually. 

We've "Started" the Programming for You

With the NCD Component Library we've "started" the programming for you.  We say started because these are fully functioning samples but we've also included the source code so you can customize them to your exact needs.  Start by downloading the NCDComponentSetup.zip file from the NCD Component page.
Download NCD Component Library

Over 40 samples included with this download!  To view screen shots of each example visit our NCD Component Library Page.
