USB Relay Devices
Our full line of USB compatible controllers suit nearly any application, and our USB modules come with a long history of proven stability. Customize your project with exactly the options you need. From General Purpose, High Power or Signal Switching, we have you covered with our SPDT, DPDT, and SPST Relays. The versatility of our USB relay controllers ensures an easy and reliable solution to whatever your switching needs.
USB Relay Controllers with 16 or More Relays
NCD manufactures the largest USB Relay controllers in the world, with options for 16, 24, 32, 48, 56, and 64 on-board relays. Expansion options allow NCD relay controllers to scale up to 256 channels. Dual interface options are also available on the Fusion series controllers, allowing two USB ports to control the entire array of on-board and off-board expansion relays.
On-Board GPIO and Analog Inputs
Most NCD controllers come equipped with Analog inputs. These analog inputs may be used to read external sensors. Analog inputs may be software configured for 8-Bit or 10-Bit resolution, allowing for highly accurate analog sensor measurement applications. Analog inputs may be re-configured for manual control of on-board relays. Simply connect a button to the on-board analog inputs and turn relays on or off when the button is pressed. Fusion series controllers are equipped with 16 analog inputs that may be software configured as GPIO. Use analog inputs for sensor monitoring and control applications or re-program the analog inputs for TTL Input and Output (GPIO) control. Fusion controllers are equipped with two communication interface ports, allowing multiple computers to monitor and control on-board relays. Fusion controllers also include many functions to automatically control relays when external sensor reach pre-defined set-points. NCD Reactor series controllers offer a lower-cost alternative to Fusion, with some automation features and control of up to 8 on-board relays. All Reactor inputs are 8-bit analog.
How It Works
All USB devices are equipped with our proprietary firmware built into the board. This will allow you to Control one relay at a time, a bank of relays or all relays at once with manual and automatic refreshing command set. You can send commands can be sent over the virtual COM port, or our Base Station software. We make integrating into existing systems, or building entirely new ones quick and painless.
