What this Chapter Contains

Read this chapter to familiarize yourself with the input and output analog

modules.

What the FLEX Ex Analog

I/O Modules Do

The 1797-IE8 and -IE8NF modules accept up to 8 analog inputs. The inputs

are non-isolated and will accept current in either of the following two ranges:

4-20mA or 0-20mA. The default input range is 0-20mA. The inputs have both

fixed hardware filters and selectable firmware digital filters.

Similarly, the 1797-OE8 module provides as many as 8 analog outputs. The

outputs are nonisolated and will provide current in either of the following two

ranges: 4-20mA or 0-20mA. The default output range is 0-20mA.

Each module offers:

• local microprocessor intelligence for advanced features

• full functionality without switches or jumpers

• multiple data ranges that can be independently programmed

in channel groups

• lead breakage detection

• overrange/underrange alarms

• remote transmitter alarm

as well as a host of other module features.
