About the FLEX Ex Analog Modules
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.
