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:

About ProXR:

With all the control and backward/forward compatibility you have come to expect from the ProXR series command set, this controller allow you to send simple commands to activate relays, read the status of relays, activate up to 16 relay timers, and control up to 256 total relays using the XR Expansion Port.  All relays are electronically latched, simply send a command to turn the relay on, send a different command to turn the relay off.

You can send commands to activate relays, deactivate relays, control all the relays at one time, plus you can send commands that tell a relay to turn on for a few seconds, minutes, or hours.  You can assign 16 timers to any of the 256 relays, and set the timers to go off after the duration has expired.

A/D Conversion

Analog to Digital Conversion allows you to read voltage levels from 0-5 volts using 8-bit or 12-bit resolution. This is particularly useful for reading temperature sensors (one temperature sensor is built into the board, shared with analog input number 8).  A/D Inputs are also useful for reading light level sensors, thermocouples, switch closures, or just about any other kind of sensor you can think of. Built-In Pull-Up/Down Resistors keep the inputs quiet.

Updated Communication Technologies

This product has been updated to support many communication technologies.  Please reference the quick start guide for each of the associated communication technologies, as they generally all work as protocol converters to convert data to serial communications at 115.2K baud.  Please choose from any of the communication technologies below:

ProXR Series Industrial Relay Controllers

NCD has been in business since 1995, and we created the world’s first commercially available relay controller.  ProXR Industrial controllers are the best controllers on the market with over 10 years of production history and a 5-Year Repair or Replace Warranty to back it up!  There are many reasons that make ProXR the leading relay control solution.  Let’s take a look at why ProXR controllers are unique, and why industry has chosen NCD controllers for so many years:

ProXR Reliability

The firmware we designed for ProXR series controllers is ultra-stable.  Our CPU uses hardware interrupts to manage communications while processing a wide range of background tasks, such as 16 relay timers, 16 relay flashers, data parsing, and garbage cleanup.  ProXR controllers will never “drop” commands, even in the most demanding environments.  We use a hardware watchdog timer, built into our CPU.  The watchdog timer acts as a supervisor, capable of rebooting the CPU should anything go wrong so you never loose communications.  The current CPU is more powerful, more feature packed, and more stable than any other controller on the market.  ProXR controllers were designed to operate non-stop 24/7 from 0 to 85C.

ProXR Features

ProXR controllers can take control of relays in ways you may have never imagined.  Of course you can turn relays on, or off, or toggle the current state of the relays.  It’s also easy to read the status of individual relays, relay banks, or all relays on the controller.  These are basic functions every relay controller should support.  ProXR relay controllers have many features you may not expect.  For instance, ProXR controllers support 16 timers that run in the background.  Each timer can activate a relay for up to 255 Hours, 255 Minutes, and 255 seconds when activated.  Activate 16 security lights using the timers and watch them all turn off at different times.  ProXR controllers also support 16 flashers, allowing up to 16 relays to be automatically cycle on and off in the background until the flasher is canceled.  Relay grouping commands allow ProXR controllers to simulate large expensive relays using low-cost relays.  Grouping commands are used to activate a master relay plus a few of it’s neighbors simultaneously, allowing simulation of DPDT, 3PDT, 4PDT, 5PDT, 6PDT, 7PDT, and 8PDT relays using a low-cost 8-Channel SPDT relay controller.

Automatic and Manual Relay Refreshing

By default, ProXR controllers automatically update the status of relays every time you send a command.  This feature may be enable or disabled.  When disable, users have the ability to configure the relay memory without actually switching relays.  Once all the memory is configured, simply send the Relay Refresh command and all relays will refresh simultaneously.  This is particularly useful in applications that may require you to configure the on/off state of each relay and switch all relays at the exact same time.  ProXR will remember your refresh settings every time it powers up.  And while we are on the subject of power-up, ProXR relay controllers do not click when power is first applied.  This alone is one of the biggest reasons industry has chosen ProXR over the competition.

XR Expansion Port

ProXR relay controllers are equipped with a XR Relay Expansion Port.  The XR Port allows you to add more relays to your controller as your needs expands.  Combine mechanical and solid-state relay expansion controllers in any combination to accomplish your automation requirements.  We manufacture SPST, SPDT, and DPDT expansion solutions, available in 4, 8, 16, 24, and 32 channel versions.  ProXR relay controllers support up to 256 relays in firmware; however, expanding over 128 relays may not be possible if the cable length is too long.

ProXR Perks

There’s a lot of little things we did to make ProXR special.  We created Base Station Software so you can learn to use ProXR controllers using a Windows 8 or 10 PC.  Base Station supports all communication technologies and teaches you what bytes to send to your controller so you don’t have to hunt down the manual every time you want to use a new function.  Simply copy and paste the communication bytes from the Base Station User Interface into your favorite programming language.  Base Station will demonstrate the engineering behind ProXR series controllers, but if you want a preview, just take a look at the ProXR Quick Start Guide in the Resources section.  On-line videos walk you through all the major features.  ProXR controllers have a 5 year warranty and a operational life expectancy exceeding 10 years.  We built ProXR controllers to last.  We are committed to up-gradable hardware, not disposable hardware.  We use the best relays, the best communication technologies, and we have the best support in the industry.  We can help you with all of your relay control needs, no matter how complex!

LabVIEW Relay Control Support Coming in 2018

We are pleased to announce that official LabVIEW relay control drivers will be supported beginning January of 2018.  This is our first official release of LabVIEW drivers for ProXR series Relay controllers!  We are finalizing the drivers and resources now.  We will post in the News section as well as the Learn section of our site as soon as we are ready.
