Description
  • BrandAnalog
Welcome to the world of Computer Automation. This RS232 Relay Board - R242 is a perfect companion for all your computer automation projects. It is RS232 based card having 4 on board relays for switching external devices and up to 9 digital & analogue I/Os that will help you to monitor various real world scenarios using switches & different kind of sensors to monitor many parameters like Temperature, Pressure, Light, Touch, PH etc. This card is not only good for controlling Relays but a perfect example for Data Acquisition applications.

It uses existing Com Port ( you can choose the available one), which allows easy communication with the card. Any programming language that supports serial communications ( C, C#, C++, VB, VB.NET,Perl, Java etc) can be used to communicate with R242 very easily. Easy to use commands are available to communicate with R242 which handle various tasks like Switching On/Off of Relays, Controlling Digital Inputs & Outputs, Getting analog data etc.

The controller provides 4 relay outputs to control various electrical devices. Apart from this, the card has up to 9 digital input & output pins. It has also got 4 Analog input pins. All pins can be individually configured as Digital Input or Digital output on the fly.

All analog pins can be individually configured as digital I/Os also while taking care of input conditions. Each Digital pin can support a TTL or Schmitt Trigger Input or a 5V output. Each Analog pin will convert analog voltage ( Between 0 to 5V) or Higher ( through voltage divider) into 10 bit resolution raw data.This can be converted into required form using conversion formulas.

Any kind of sensor whether it is providing digital output or analogue output can be interfaced with R242 and monitored with the help of computer.
