Mount the Analog Modules on the Terminal Base Unit
The HART analog input and output modules mounts on a 1794-TB3 or
1794-TB3S terminal base unit.
1. Rotate keyswitch on terminal base unit clockwise to position 3 for the
1794-IF8IH or position 4 for the 1794-OF8IH as required for each type
of module.
Do not change the position of the keyswitch after wiring the terminal
base unit.
2. Make certain the Flexbus connector is pushed all the way to the left to
connect with the neighboring terminal base/adapter.
You cannot install the module unless the connector is fully extended.
3. Make sure the pins on the bottom of the module are straight so they will
align properly with the connector in the terminal base unit.
4. Position the module with its alignment bar aligned with the groove on
the terminal base.
