Install Your FLEX I/O Frequency Input Module 21
Wire the Terminal Base Units
Wiring the FLEX I/O Frequency Input module is done using the 1794-TB3G,
1794-TB3GK or the 1794-TB3GS terminal base unit.
1794-TB3G, 1794-TB3GK and 1794-TB3GS Wiring Connections
Connect Wiring to the FLEX I/O Frequency Input Module
Wiring to the Frequency Input module is made through the terminal base unit
on which the module mounts.
The module is compatible with the 1794-TB3G, 1794-TB3GK and
1794-TB3GS terminal base units.
ATTENTION
Take note of the following considerations when wiring your
terminal base units:
•AIl modules must be frequency or analog modules for the
daisychain configuration.
•Use the individual type of configuration for any "noisy" DC
digital I/O modules in your system.
•All modules powered by the same power supply must be
frequency or analog modules for the combination type of
configuration.
