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