Electronic Trigger RS232 Control Board

Electronic trigger output with RS232 control board

This is an RS232 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 a dry contact output (or optical isolated NPN output) to control external devices like door or barrier.

Product Code [PIC-026]

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

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 any of your 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…

RS232 control trigger output

Features

  • 1x dry contact relay output trigger. (for up to 24V 0.5A signal)
  • Power up from a wide voltage range 7V, 9V, 12V-24V (0.5A).
  • Convenient test button.
  • On-board adjustable output pulse timing (20mSec to 1000mSec).
    (new model only) Adjustable POT for configuring pulse timing from 10msec to 1sec
  • Precise pulse timing can be adjusted through RS232 commands.
  • Selectable output trigger, NO (normally open) or NC (normally close).
  • Small board size measuring 71 x 28mm, light in weight.
  • RS232 communication (Can use normal RS232 (DB9) cable or cross cable).
  • Default RS232 settings: 9600bps, 8bit data, 1 stop bit, no parity.

Optional Features

  • Learning mode to clone pulse timing from external device (e.g a coin or notes acceptor).
  • Can become a sensor to detect pulse width from external device.
  • Opto-isolated npn transistor output trigger. (or solid state output)

Please specify your requirements or application if you requires these optional features.
