Digital and Analog I/O Technical Note
Introduction
Analog and digital I/O ports on ION meters let you bring in a variety of data into a
common system. This simplifies data gathering and provides the following
capabilities. Meter analog and digital I/O ports let you:

There is a range of I/O solutions available depending on your application.
Onboard I/O provides fast and robust performance for time-critical applications.
Configuration is simple and integration is seamless.

For extensive I/O requirements with the ION 8000 Series meter, you can use the
I/O Expander — this device was designed and tested with the ION 8000 Series
meter, and provides reliable performance.

You can use meters with Modbus master capability (ION 8000 Series, ION 7500,
and ION 7600 meters) for extensive I/O requirements; when communication speed
is not required, you can use the Grayhill OpenDAC I/O system (see the Grayhill
OpenDAC and ION Technology technical note for more information). Other ION
meters also use Grayhill I/O products, such as the ION 7300 relay extension board
and the ION 7700 expansion boards.
