Contact Closure Monitoring
With this Scan Series Controller you can monitor Contact Closure Inputs using a computer. With minimal programming, data collection and control from a single controller allows any computer to talk this device. The SCAN Series command set allows you to read anywhere from 1 to 32 banks of 8 inputs in a single query. A single bank contains 8 inputs. Reading 32 banks will report the status of 256 inputs. It doesn’t stop there, because we are focused on relay control you can add relays to the board (up to 256) and control them using the data collected from the inputs. Remember these are contact closure inputs ONLY no voltage can be applied to these inputs. Simply connect to your computer and this board mounts as a Virtual COM Port on your PC, allowing easy programming from any language that supports serial communications.
Mounts as a COM Port
This ProXR series controller connects to the USB port of your computer and will mount as a COM port on your PC. USB Drivers will most likely be needed and can be found in the resources section to the right and will also be available in the Base Station Software. Once powered up, the controller waits for a command. A command consists of a few bytes of data in numerical format 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.
Base Station Software is available at no charge to get you up and running fast (more on Base Station below). Once powered up, the controller waits for a ProXR command. A command consists of a few bytes of data in numerical format 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. When a command was sent to read the status of the contact closure the status is sent back.

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:
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 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.
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
We are pleased to announce that official LabVIEW relay control drivers are supported. This is our first official release of LabVIEW drivers for ProXR series Relay controllers!
900HP-S3B Industrial Wireless Mesh
Long-Range Wireless Mesh networking is our favorite of all wireless communication technologies. This is the ONLY communications technology NCD recommends on the factory floor, operating at a safe 900MHz. Mesh technology will hop data from one location to another to reach its intended destination, users do not need to do anything other than make sure wireless modules stay within hopping range of each other. We use the Digi 900HP-S3B module in many of our products, as this is the best industry has to offer. With a 2 mile range between modules and up to 8 hops, it is possible to cover 16 miles of wireless territory using this technology. Using high-gain antennas, this module is capable of communicating to a remote module up to 28 miles away. Please note that data hopping only works between live devices. Data will not hop between sleeping sensors. Data will hop from sensors to gateways and modems. Data will also hop between gateways and modems.
E3C DropNet is our own communication technology, which allows up to 256 devices to share a single 3-wire data bus. Communication distances of over 1,000 feet are achievable using repeater modules on the bus. E3C DropNet allows you to communicate to each of the 256 devices without data collisions, and is based on a modified RS-232 signal. DropNet is very similar to RS-485, but the protocols are easier to implement with more nodes, but at lower communication speeds. Users have many options for a head communication technology. For instance, a USB head will convert a USB interface to the DropNet 3-Wire bus and allow all 256 devices to communicate to the USB port of your computer. Optionally, the USB interface may be replaced with RS-232, Ethernet, WiFi, Bluetooth, or Industrial Wireless technologies. Communication speeds of 115.2K Baud are possible, but slower communication speeds means longer distances.
