I/O Solutions
ION meters offer you a range of onboard I/O. For expanded I/O applications, you
can use Grayhill products (see the Grayhill OpenDAC and ION Technology technical
note for further information). Configuring onboard and expanded I/O is the same
with ION software.
Every ION meter has a set of software modules that control its analog and digital
onboard I/O ports. There is one ION software module that corresponds to each
hardware input or output port, for example, one Digital Input software module
corresponds to one hardware input port.
Onboard I/O requires minimal setup with Designer software. The I/O Expander
for the ION 8000 Series meters and expansion boards for the ION 7700, ION 7300
Series, ION 7500, and ION 7600 require similar setup to the onboard I/O with
Designer software.
Refer to your meter User’s Guide or technical documentation, or the online
ION Programmer’s Reference for complete details on how to link and configure these
ION modules using Designer software.
Onboard I/O for ION Meters
The number of digital and analog inputs and outputs on each ION meter is listed
below.
* Some digital inputs/outputs and all analog inputs require the installation of an optional circuit board
inside the meter. See the meter’s data sheet for complete details.
