The Sensorsoft protocol based Relay is a low cost device for switching equipment at a remote location, ON or OFF, using your PC or UNIX workstation.

Equipment without remote control features sometimes require control remotely to avoid the need for expensive trips to a remote location or help from on-site personnel. Developing a solution to this type of problem often involves an engineer who can create custom software and hardware. The use of X-10 devices for this purpose has been known to fail during electrical interference making them unusable in a business critical environment. The Sensorsoft Relay is a simple and reliable way to use your computer to restart or turn ON/OFF equipment without the need for remote operators or time consuming trips to a remote location.

The Sensorsoft Relay connects via cable to a serial port on your computer and can be located thousands of feet away without the need for a battery or *external power adapter. Our unique serial "plug and go" technology insures that you can install it quickly and start using it without a fuss. The Sensorsoft Relay can be used to control *AC or DC devices using its DPDT (Double Pole Double Throw) relay contacts.

Our software provides a convenient way to display the ON/OFF state of your remote equipment and set the desired state you want with your computer.

Applications

  • Control of door strike solenoid or lock
  • Re-boot or re-start locked-up equipment
  • Remote control of experiments
  • Computerized ON/OFF load control
  • Manage ON/OFF state of power consuming devices
  • Applications in building management or remote sheds

User Manual
