4. Connect 24V DC to terminal 34 on the 34…51 row (C), and 24V
common to terminal 35 on the 34…51 row (C).
5. If daisychaining the 24V DC power to the next 1794-TB3G, 1794-
TB3GK or 1794-TB3GS base unit, connect a jumper from terminal 50
(24V) on this base unit to terminal 34 and from terminal 51 (24V DC
common) to terminal 35 on the next 1794-TB3G, 1794-TB3GK or
1794-TB3GS base unit.
6. Connect output power wiring to terminals 37 (+) and 39 (-) for outputs
0 and 1, and terminals 46 (+) and 48 (-) for outputs 2 and 3.
ATTENTION: To reduce susceptibility to noise, power frequency
modules and digital modules from separate power supplies. Do not
exceed a length of 10 m (33 ft) for DC power cabling.
ATTENTION: Use extreme care when connecting wiring to an
adjacent terminal base unit. Wiring for the 1794-TB3G and
1794-TB3GS terminal base units is different from other 1794 terminal
base units.
ATTENTION: Do not daisychain power or ground from the 1794-
TB3G, 1794-TB3GK or 1794-TB3GS terminal base unit to any AC or DC
digital module terminal base unit.
ATTENTION: 24V DC power must be applied to your module before
operation. If power is not applied, the module position will appear to
the adapter as an empty slot in your chassis. If the adapter does not
recognize your module after installation is completed, cycle power to
the adapter.
