24 How to Install Your Analog Module
Connecting wiring for the individual analog modules is shown on:
Connecting Wiring using a 1794-TB3, -TB3T, -TB3S or -TB3TS
Terminal Base Unit
1. Connect the individual signal wiring to numbered terminals on
the 0–15 row (A) on the terminal base unit. (Use Belden 8761
cable for signal wiring.)
2. Connect each channel signal return to:
1794-IF4I – the associated terminal on row A.
1794-OF4I – the corresponding terminal on the same row (A)
1794-IF4XOF2I – inputs – the associated terminal on row A;
outputs – the corresponding terminal on the same row (A).
3. Refer to Table 2.1 or Table 2.2. Connect +24V dc to designated
terminals on the 34-51 row (C), and 24V common todesignated
terminals on the 16–33 row (B).

ATTENTION
Connect only one current or one voltage signal per
channel. Do not connect both current and voltage on
one channel.
ATTENTION
To reduce susceptibility to noise, power analog
modules and discrete modules from separate power
supplies. Do not exceed a length of 33 ft (10m) for
dc power cabling.
