Take note of the following considerations when wiring your
ATTENTION
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.

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.

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.
