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 (-)
