Ideal for Monitoring Voltages

While Analog to Digital Converters are ideal for monitoring voltages in the range of 0 to 5 volts DC. Our current product line is widely used for Temperature monitoring, Light Level monitoring, with minimal integration time. Analog to Digital conversion is the process of converting a voltage to a number. The higher the voltage (not exceeding 5VDC), the higher the number. 8-Bit Analog to Digital Converters offers numeric values from 0-255. 10-Bit ADC offers numeric values from 0 to 1023. 12-Bit A/D offers numeric values from 0-4093. Simply query the controller to ask it the voltage on the A/D input. Up to 48 analog inputs are supported on some controllers.

Analog to Digital Relay Boards

We have an extensive selection of relay boards that have eight channel 8/10-Bit Analog to Digital Conversion built into the board, look for AD in the part number.  All Relay Boards that offer Analog to Digital Conversion feature the ProXR Command Set and an XR Expansion Port, simply look for PROXR in the part number.  Built from the ground up with expansion in mind, simply chain the XR Expansion Modules to the XR Expansion port, one after another, to meet your computer controlled switching requirements to add up to 256 relays.  All are of course SignalSwitch compatible.

Add A to D to Any UXP Board

Add Analog to Digital Conversion to any NCD ProXR controller with a UXP Port (look for UXP in the part number) using the UAD1216 Expansion Module! The UAD1216 is an 8-Bit/12-Bit 16-Channel Analog to Digital Converter Expansion Module designed to attach to any NCD ProXR controller with a UXP expansion port. That's right, turn your existing controller into an analog to digital converter!   Visit our UAD1216 page for more details.

NCD Component Library

Fully functioning Analog to Digital Conversion programs are included with the NCD Component Library. 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.  The NCD Component Library is a plug-in for the Visual Studio 2005/2008 that greatly simplifies the communications to the NCD product line.  The samples can be run in Visual Studio and fully customizable to your needs.  Eight different A/D samples are available including an AD Temperature Converter, to view screen shots of each sample visit our NCD Component Library Page.  Start by downloading the FREE NCD Component Library and you will be communicating with any NCD device faster that ever!

The above screen shots show two of the eight available fully functioning A/D samples that are available with the NCD Component Library.  View all the examples on our NCD Component Library Page.
 

N-Button Lite

N-Button Lite creates up to 8 buttons or widgets to control relays without any programming. A new button will be created and placed on the desktop of your computer for each relay that you want to control. N-Button Lite supports Serial Port/ USB and Network connection between PC and relay board. N-Button Lite Manager makes it easy to add any type of button to the desktop and change the properties.

Analog to Digital meters can also be added to your desktop to instantly read the status of any sensor or probe you may have connected to the board. Each meter is customizable and can be changed without any programming knowledge.

Relay Button widgets turn on/off relay directly. It has never been so easy to control relays before.
Relay Status widgets show status of the relay automatically.
A/D Meter widgets display the value of A/D channel automatically.
Customized Button widgets allows you send any of the commuands in the manual to relay board.

N-Button Lite is available as a free download. Look for the Desktop Control section to the right to download.

N-Button Lite version supports up to 8 widgets. If you want to add more than 8 widgets, simply upgrade to the N-Button Standard version.

Reactor Relay Controllers

Analog Inputs Trigger Relays
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.

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.

Key Fob Control

Override A/D Inputs with a Key Ring Fob
Key Fob users are 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 of the A/D inputs on the board. 
    Key Fob Relay Applications Include
  • Garage Door Opening/Closing
  • Override Existing Programming
  • Lighting Applications
  • Pump Activation
  • Anywhere You Need Quick On-Location Switching
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.
