4 Overview FLEX I/O and FLEX Integra Product Data
About the FLEX Integra
System
FLEX Integra I/O consists of a range of digital and analog modules, all
capable of use with 1794 FLEX I/O adapters and other FLEX I/O
modules. Each module is available with either screw-cage or
spring-clamp wire terminations.
TIP
FLEX Integra modules were designed to fit to the right of
your FLEX I/O modules. Be sure to place your FLEX
Integra modules to the right of your FLEX I/O modules
when designing your system.

Use the adapter to power the internal
logic for as many as eight I/O modules
and transfer the I/O data back to a
PLC

processor or a SLC

processor via
one of several available networks.
Two separate connection terminals
for field power let you daisy-chain
power connections to adjacent
FLEX I/O terminal bases.
Insert the module into your system
using the positive-locking flexbus
connectors.
Terminate all of your wiring on the
module with no need for terminal
blocks.
Use the terminals to daisy-chain
power connections to adjacent FLEX
I/O terminal bases, or connect
individual power supplies to each base
to isolate modules.

ATTENTION
!
Do not remove an Integra module under power.
Removing the module under power will break the
electrical backplane (flexbus) connections. This can
cause personal injury or property damage by:
• sending an erroneous signal to your system’s field
devices causing unintended machine motion
• causing an explosion in a hazardous environment
• breaking communications beyond this module
