USB Relay
Control By Onboard USB Interface

USB Relay Controllers allow computer controlled switching using the USB port of your computer. An NCD USB Relay Board emulates a COM port, allowing you to speak to the relay board using any programming language that supports serial communications. COM drivers allow you to assign any COM port to the USB Relay Board. An NCD USB Relay Driver supports 8-Channels of 8-Bit / 10-Bit Analog to Digital Conversion (A/D) or UXP Expansion Port, and includes an XR Relay Expansion Port for adding additional relays to the USB Relay Controller Board.

USB Relay Options

USB Relays are available with SPDT 5, 10 and 20 amp, SPST 30 amp and DPDT 1, 3 & 5 amp relays installed.

Control these USB Relays through the USB port of your computer.  The controller mounts as a virtual COM port for easy programming in almost any language.

USB Relay with the Industry Leading Command Set

Selecting The USB Interface

By selecting the USB interface you will be sending commands through the USB port of your computer to the board.  Boards on this page are equipped with a ZUSB communications module that adds USB communications to the board.  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 the relay activates.

Selecting a USB Relay Board

Below you will find all the 32-channel USB Relay Controllers that are available.  The difference being the amperage of the relays installed and the type of relay.  Choose the controller that fits the amperage you are switching.  You will find SPDT relays in the 5, 10 and 20 amp versions and an SPST version in the 30 amp version.  For more information on selecting the correct relay for your application see Choosing a Proper Amperage.

Selecting a USB Relay Series

The USB Relay boards are available in the ProXR Lite and ProXR versions. Both versions have the same firmware installed and accept the same ProXR command set, the industry leading command set for controlling relays.  The ProXR Lite version is non-expandable, the ProXR version is expandable to 256 relays.  When you find your controller click on the Full Description link to view full specs, watch setup videos, download software and purchase.
