Connect Wiring

Connect the wiring for the 1794-TB3G and 1794-TB3GS terminal bases as shown in the

following figure:

Terminal Base Wiring for the 1794-IE12/A Analog Input Module

ATTENTION: To reduce susceptibility to noise, power analog modules and

digital modules from separate power supplies. Do not exceed a length of

10 m (33 ft) for DC power or analog I/O cabling.

ATTENTION: Do not daisy-chain power or ground from this terminal base

unit to any AC or DC digital module terminal base units.

ATTENTION: Do not exceed a length of 10 m (33 ft) for signal cabling.

I = Current [1794-TB3G shown]

V=Voltage

C-0...C-11 = Returns for I or V connections 0...11

+24V DC = Terminals C-34 and C-50

COM = Terminals C-35 and C-51

Chassis ground (CG) = Terminals B-16, B-33, C-38, C-40...C-45, C-47

NC = No connection

For daisy-chaining: Supply in – C-34 (+) and C-35 (-)

Supply out – C-50 (+) and C-51 (-)
