USB Relays are essentially software controlled ON/OFF switches which can be connected to the USB port of a PC or Tablet and controlled via software commands.
When connected to the USB port of a PC, a USB Relay allows a user to turn a connected device such as a fan, light or valve   We offer these devices in tandem with our USB or wireless load cells or any of our digital USB or wireless sensors to enable users to control devices based on certain values that can be obtained from our digital sensors.

We offer one channel, two channel or eight channel USB Relay devices and we offer the ControlVUE software which enables a user to control up to eight external connected devices.  This solution allows you to build an inexpensive force based control system using a PC.
