USB Controlled Relay

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

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

Choose How Many Relays You Need Below

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

How many relays do you need?  Below you will find all the USB Relay Control that are available.  Each section is broken down by the number of relays installed on the board.  Choose how many relays you require and click that link.  This will bring you to a page where you will select a board by how many amps you are switching.  USB Relays are available with up to 32 relays onboard but they can be expanded up to 256 total relays.
