Wiring to a 1794-TBN or 1794-TBNF Terminal Base Unit
1. Connect individual input or output wiring to the even numbered
terminals on row (B) as indicated in the table below.
2. Connect the associated return wiring to the corresponding odd
numbered terminal on row (C) for each input or output as
indicated in the table below.
3. Connect 24V dc to terminal 34 on row (C).
4. Connect 24V dc common to terminal 16 on row (B).
5. If continuing power to the next terminal base unit, connect a
jumper from terminal 51 (24V dc) on this base unit to terminal
34 on the next base unit.
If continuing common to the next terminal base unit, connect a
jumper from terminal 33 (24V dc common) on this base unit to termi-
nal 16 on the next base unit.
