1794-TBN and 1794-TBNF Terminal Base Wiring for 1794-OA8I
Connect Wiring for the 1794-OA16
1.
For 1794-TB2, 1794-TB3, or 1794-TB3S
– Connect individual output wiring
to numbered terminals on the 0…15 row (A) as indicated in the Wiring
Connections for 1794-OA16 table.
For 1794-TBN
– Connect individual output wiring to terminals 0…15 on rows
B and C.
2.
For 1794-TB2, 1794-TB3, or 1794-TB3S
– Connect the associated VAC
common (L2) lead of the output device to the corresponding numbered terminal
on the 16…33 row (B) for each output as indicated in the Wiring Connections
for 1794-OA16 table. The V AC common terminals of row (B) are internally
connected together.
For 1794-TBN
– Auxiliary terminal blocks are required to connect the
associated L2 common for each channel. Connect the L2 side of the load together
and then connect to L2 on the power supply.
3.
Connect 120V AC power L1 to terminal 34 on the 34…51 row (C).
4.
Connect 120V AC common L2 to terminal 16 on the 16…33 row (B).
5.
If daisychaining power to the next terminal base, connect a jumper from terminal
51 (120V AC L1) on this base unit to terminal 34 on the next base unit.
6.
If continuing 120V AC common (L2) to the next base unit, connect a jumper
from terminal 33 (120V AC common L2) on this base unit to terminal 16 on the
next base unit.
IMPORTANT
Total current draw through terminal base connection is limited to 10 A.
Separate power connections to each terminal base may be necessary.

Connect outputs to even numbered terminals on row (B).
Connect isolated 120V AC (L1) to odd numbered terminals on row (C).
Individual isolated 120V AC common (L2) must be run externally to each
of the output devices.
