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.
Connect any signal wiring shield to functional ground as near as possible to the module when using the
1794-TB2, -TB3, -TB3K -TB3S, -TBN or -TBNK. With the 1794-TB3T and -TB3TS, use terminals C-39 through C-46.
!
ATTENTION
Signal
Type
Only connect either a voltage signal or a current signal 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.
