To reduce susceptibility to noise, power analog modules
and digital modules from separate power supplies. Do
not exceed a length of 33 ft (10m) for dc power cabling.
Do not daisy chain power or ground from this terminal
base unit to any ac or dc digital module terminal
base units.
Do not exceed a length of 33 ft (10m) for signal cabling.

+V dc Power for 1794-TB3T and -TB3TS: C-34, 35, 50 and 51
Connect any signal wiring shields to functional ground as near as possible to the module when using the 1794-TB2, -TB3, -TB3K, and -TB3S.
With the 1794-TB3T and -TB3TS, use terminals C-39 through C-46.
1. A-9, A-11, A-13 and A-15 are internally connected in the module to +V dc common.
Terminals 35 through 50 are not used on 1794-TB2
Connect +V to C-34
Connect +V common to B-16
Use B-33 and C-51 for daisy-chaining to the next terminal base unit.
!
Only connect either a voltage input or a current input per channel, not both.
To reduce susceptibility to noise, power analog and digital modules from
separate power supplies. Do not exceed a length of 3M (9.8 ft) for DC
power cabling.
