USB ProXR Enhanced with A/D

USB Virtual COM Relay Controller with 8-Channels of
Analog to Digital Conversion and XR Expansion Port

About USB:

Our USB ProXR Series Relay Controllers make it easier than ever to add computer controlled switching to your most demanding computer control applications.  Simply connect to your computer and this controller mounts as a Virtual COM Port on your PC, allowing easy programming from any language that supports serial communications.

This ProXR series controller connects to the USB port of your computer and requires a 12VDC Power Supply.  Once powered up, the relay controller waits for a command.  A command consists of a few bytes of data.  Usually between 2 and 6 bytes.  Once the command has been received, the controller processes the command, and sends you back ASCII character code 85 to signal the completion of your command.

ZUSB Modules

This board is equipped with a ZUSB Module. The ZUSB communications module adds USB communications to all NCD devices equipped to accept modular wireless communication modules. The ZUSB is powered from the USB port of your computer and includes a 6' USB Cable. The ZUSB is available in three varieties:

DPDT Relay Controller

This device has DPDT relays installed.  A single DPDT relay is made up of 2 SPDT switches.  Each relay acts as two switches that are activated at the same time.  This allows two independent signals to be switched at one time.  In effect, there are two independent switches on a single DPDT relay - they will always switch together.


There are two connectors with Normally Open, Normally Closed and Common for each relay allowing two separate connections.  The picture above shows the 4-channel connectors.  The diagram to the right shows the how the arms of the common connector swing from the Normally Closed to the Normally Open positions when energized.  Wiring to either the NO or NC can produce your desired results.  For more information on selecting the correct relay amperage for your application see Choosing a Proper Amperage.

Easy Software Development

Most of our customers write their own program for controlling these devices. Since you can use almost any programming language, you can use one that is most familiar to you so you don't have to learn a new language.  These boards support the Serial Port Profile, meaning they will mount to the computer as a virtual com port. This makes it very easy to send commands to the device.

Plug-In for Visual Studio

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.  Over 40 samples included with this free download!  Component Library.

Base Station Software

Base Station will assist you in learning how this device functions and is the ultimate reference tool for setting up, testing and controlling this device.  Base Station software supports every feature of this device - no other controller manufacturer even comes close to offering this type of software.  Base Station works by communicating with your controller to identify the model and provides the appropriate graphical user interface for setting up and testing the identified device.  To help you get started and learn this controller Quick Start Guides are available for just about every feature.  As you discover a feature in Base Station a link is provided where you can easily download the Quick Start Guide.

ProXR Relay

We've looked at the interface and the programming now let's take a look at the board design itself.  The ProXR series controllers are manufactured by hand for a highly accurate and reliable design.  Equipped with the XR Expansion Port additional relays can be easily added.  Fully tested before they leave the production facility each ProXR Lite controller 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!

Add Relays as Your Needs Grow

The ProXR series controllers are expandable up to 256 total relays.  The controller is fitted with an XR Expansion Port where you can add expansion boards to this relay.  Expansion boards can be added until you reach 256 total relays.  The Expansion Boards get their logic from the main board and will require 12 VDC power. Expansion boards do not need to be the same relay amperage as the main board or other expansion boards.

16 User-Programmable Timers

The ProXR Series controllers have 16 user-programmable timers. Each independent timer can be assigned to any relay, and can be programmed to hold the relay in the On state, or to pulse the relay at the end of the timer.  The ProXR timing features are ideally suited for Watchdog, Keep Alive, and Server Reboot applications, as well as sprinkler systems, gate openers, and lighting applications.  Relay Timing Features support two modes of operation: Duration and Pulse. Duration timing is ideally suited where a device should be activated for a period of time. Pulse timing mode is designed specifically for server reboot applications, whereby, if the timer is not reset periodically by your software, the timer will run out and reboot your computer.

Read Analog Sensors

This ProXR controller offers a 8-Channel 8/10-Bit Analog to Digital Converter in addition to relay control.  Read and control from 8 sensors per board from 0 to 5 volts!

ProXR Enhanced Firmware Installed

This board has ProXR Firmware installed that responds to the full ProXR Command Set.  The ProXR Firmware is the industry leading firmware for controlling relays with more commands and functionality than any other board on the market.  The list of commands and perameters this board is capable of is extensive.  ProXR Enhanced is the newly released enhanced version of the ProXR Firmware with more commands, more functionality and better control than ever before!  For a detailed list of all the commands with descriptions see our ProXR Enhanced Command Set.
