Electronic Trigger RS232 Control Board

Electronic trigger output with RS232 control board

This is an electronic trigger board which is controlled via an RS232 communication cable. Any computer or controller can send a command through the RS232 line and trigger an optical isolated NPN output to control external devices like door or barrier.

The NPN output allows you to trigger a signal to activate other devices. If you need to use this output to control high power/current devices, you can interface this NPN output via a relay interface.

A quick test push button (optional) is available on the board which allows you to trigger the output manually without having to send the command via RS232.

The board feature a controller which the algorithm can be customised to your other special requirements.

Application

  • trigger open for vehicle barrier control
  • vending machine
  • coin acceptor trigger emulator
  • open motorised sliding door
  • release security EM lock (electromagnetic lock) or door strike for the office door
  • trigger other external controllers
  • via an external relay switch to power on high power appliances like lighting, motor, etc…
