Description
USB Relay Devices from NCD
Our USB Relay products make it easy for computers of all types to control relays and monitor analog inputs. USB Relay boards allow you turn relays on or off, flash relays continuously, control relays for a duration of time, and control relays in groups using a cross-platform compatible USB interface. NCD ProXR Lite series controllers are a widely adopted standard used by industry for many years. Equipped with your choice of 1, 2, 4, or 8 on-board relays, the ProXR Lite series USB Relays suit the needs of most of our customers. Integrated Analog to Digital Converters may be used to manually control the relays, or they may be used to read external sensors. Equipped with 8 or 10-Bit resolution, the ADC built into NCD USB Relays add tremendous flexibility for various application requirements. This device includes a NCD USB Interface module which will mount as a Virtual COM port on your computer. Simply Open the COM port at 115.2K Baud and start communicating. The USB interface is compatible with all Windows, Linux, Mac, and Android operating systems. Most systems do not require a driver; however, we use FTDI interface chips in our products and drivers are available from their web site if required for your system (www.ftdichip.com).
Getting Started with an NCD USB Relay Module
Start by downloading Base Station at https://ncd.io/start. Plug in one of our USB relay boards and run Base Station. This software tool is designed to teach you all the features built into your controller and provide you with example commands. NCD USB Relays mount as a virtual COM port on your PC. Simply choose the new COM port and click OK to begin communicating with the USB Relay board. Base Station was written for Windows using Visual Studio (source code available). Base Station shows you all the commands you need for controlling relays and monitoring external sensors.

Our USB interface module makes it easy to control our devices using the USB port. Simply plug into any available USB port and start controlling our devices using standard serial commands. NCD USB Interface modules feature genuine FTDI USB to Serial Converter Chips, the very best in the industry. Learn more about our USB Communications module here.
Relay Options
10-Amp SPDT Signal Relay Option
This controller is available with a 10-Amp relay option, allowing control of higher-power loads up to an absolute maximum of 240VAC at 10 Amps. Ideal for general purpose switching applications, this relays is focused on power-switching, and should never be used for low-power signals due to a higher On resistance of up to 150 Ohms when relay contacts are new (contact resistance drops to less than 1 Ohm after break-in period). The 10-Amp relay is of the SPDT variety, which provides Common (C), Normally Open (NO), and Normally Closed (NC) connections. Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated. All connections are made via screw terminals, capable of accepting up to 12 AWG wire. Review Datasheet
5-Amp SPDT Signal Relay Option
This controller is available with a 5-Amp relay option, allowing control of higher-power loads up to an absolute maximum of 240VAC at 5 Amps. Ideal for general purpose switching applications, this relays is focused on power-switching, and should never be used for low-power signals due to a higher On resistance of up to 150 Ohms when relay contacts are new (contact resistance drops to less than 1 Ohm after break-in period). The 5-Amp relay is of the SPDT variety, which provides Common (C), Normally Open (NO), and Normally Closed (NC) connections. Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated. All connections are made via screw terminals, capable of accepting up to 12 AWG wire. Review Datasheet
