5. Press firmly and evenly to seat the module in the terminal base unit.
The module is seated when the latching mechanism is locked into the
module.
6. Remove cap plug and attach another terminal base unit to the right of
this terminal base unit if required.
Make sure the last terminal base has the cap plug in place.
Wire the Terminal Base
Units Wiring the FLEX I/O HART analog input modules is done using the
1794-TB3 or the 1794-TB3S terminal base unit.
Connect Wiring to the FLEX
I/O HART Analog Modules Each 1794-IF8IH input can be operated from an analog field device signal,
and each 1794-OF8IH output channel can operate an analog field device.

IMPORTANT
The adapter is capable of addressing eight modules. Do not
exceed a maximum of eight terminal base units in your system.
ATTENTION
The FLEX I/O analog modules do not receive primary operational
power from the backplane. +24V DC power must be applied to your
module before operation. If power is not applied, the module position
will appear to the adapter as an empty slot in your chassis. If the
adapter does not recognize your module after installation is
completed, cycle power to the adapter.
IMPORTANT
When interconnecting several lines, you must consider the total
accumulated power.
