Arduino 4-20 mA + RTC Shield User's Manual

1 INTRODUCTION

The Arduino 4-20mA + RTC is a 4-20mA current signal adaptation board. This
Shield has 4 input channels which allow converting signals that come with this
industrial standard.
The Arduino 4-20mA + RTC has a DS1307 Real Time Clock which enables you to
add a time stamp to every converted data. The Real Time Clock has a backup power
supply, using a 12mm Coin type battery.
This Shield works with type 2, 3 and 4 current transmitters, and it can be connected
to Duemilanove, Mega and Uno platforms. To work with the Arduino 4-20 mA + RTC
Shield you need to connect an external 9-12 VDC power supply for its correct
operation.
With this board you can connect to any industrial sensor, monitor and even control
a variable directly from your Arduino board!
