4-Channel High-Power Relay Controller with 8-Channel ADC
This ProXR Industrial relay controller is capable of switching 4 on-board 20-Amp SPDT or 30-Amp SPST, ideal for high-power switching applications. Each 20-Amp SPDT relay includes 3 quick-connect terminals for normally open, common, and normally closed contact closure relay output connectivity. The 30-Amp SPST relay has two quick-connect terminals for normally open and common connections. This controller features a modular communications interface, capable of accepting USB, RS-232, Ethernet, WiFi, Bluetooth, Industrial Wireless communication modules, and more. On-Board Analog to Digital Converters allow monitoring of 8 inputs at 8 or 10-Bit resolution. Analog inputs are ideal for connecting external sensors, or connect buttons and switches to the inputs and configure the controller to manually control relays when buttons are pressed. Turn relays on or off, toggle the state of a relay, or trigger relay flashers all from external switches. Expand ProXR controllers to switch more relays of various types using the XR Expansion Port. Simply plug in any XR Expansion Relay Controller and you are ready to switch solid state relays, DPDT signal relays, general purpose SPDT relays, and high-power relays.
ProXR Analog to Digital Inputs are Used for Sensor Monitoring
AD8 8-Channel 8/10-Bit Analog to Digital Converters
This controller is equipped with 8-Channels of 8/10-Bit Analog to Digital Converters, capable of reading analog voltages from 0 to 5 Volts DC. The ADCs on this controller allow monitoring of external sensors or contact closure input detection. Connect external temperature sensors, light sensors, current sensors, buttons, switches, or anything else that generates a 0-5VDC analog or contact closure output. With 8-bit resolution, analog inputs will convert 0-5 Volt signals into a value from 0 to 255. With 10-bit resolution, values of 0 to 1023 may be measured. Input resolution is software selected. Simply ask the controller for the analog value of each input, and the controller instantly responds.
Use the Relay Activator to Configure Analog Inputs for Direct Control of Relays
Relay Activator and Analog Inputs
The Relay Activator control panel allows analog inputs to directly control relays. Simply connect the analog inputs to buttons or switches and trigger basic relay on or off functions to take manual control of the on-board relays. The Relay Activator control panel allows you to define 8 functions for each of the 8 inputs. Functions include turning relays on or off, toggling the state of relays, momentarily flash a relay, momentarily toggle the flashing function of a relay, turn all relays on, turn all relays off, and push notification events. When push notification events are configured, the controller generates a packet of data every time the inputs change state.
Base Station Software Controlling NCD Relay Controllers
Base Station Software
Base Station Software was designed to help you learn the ProXR command set. Explore ProXR features using our Graphical User Interface. Watch data bytes flow to and from the board, so you easily understand the command execution process. There is no faster or easier way to learn how to automate than Base Station, as it was designed to work with our complete array of communication modules, including Wireless, Ethernet, USB, RS-232, and many more. You only need a Windows 8 or 10 Computer to Run Base Station. Base Station was written in Visual Studio, and we even provide the source code to help you on your way!
ProXR Series Communication Options
We take communications seriously, as we believe in a modular communications and firmware that properly supports scalability into future interface technologies. ProXR controllers support API communications, which effectively wrap every command with a header, payload, and checksum to ensure reliability. NCD API commands increase processing speed because no serial timeout is required prior to command processing. NCD API commands increase reliability, as only a proper checksum will authenticate a command and allow it to process. When we first implemented API, internet communications via a TCP/IP socket could be realized because the timing problems of internet communications were eliminated. While API is optional, it is strongly advised. Our Base Station software uses API communications, so it’s possible to control a ProXR controller over the internet after configuring port forwarding on your router.
ProXR series controllers are the world’s most adaptable controllers, capable of communicating with a wide variety of communication options. Pick any of your favorite communication technologies: Bluetooth, USB, WiFi, Ethernet, Ethernet Web-i WebRelay, 802.15.4 Wireless, ZigBee Mesh, Key Fob, or RS-232. ProXR easily adapts to the communication technologies you need most. We are committed to modular communications, so your ProXR series controllers can easily be retrofitted for other applications as your needs change. ProXR controllers are never obsolete, as we are actively releasing new communication technologies that greatly enhance the connectivity of our ProXR series controllers.
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!
