row C, and the -V common/return to terminal 16 on the
16…33 row B.
4. If daisy-chaining power to the next terminal base, connect a
jumper from terminal 51 (+V DC) on this base unit to
terminal 34 on the next base unit.
5. If continuing DC common to the next base unit, connect a
jumper from terminal 33 (common) on this base unit to
terminal 16 on the next base unit,
6. For both 1794-TB3 and 1794-TB3S bases, connect wiring
shields to functional earth ground as near as possible to the
module.
ATTENTION
To reduce susceptibility to noise, power analog modules and digital modules
from separate power supplies.
Do not exceed a length of 3 m (9.8 ft) for DC power cabling.
