1794-TB2, 1794-TB3 and 1794-TB3S Terminal Base Wiring for the
1794-OA8
1794-TBN and 1794-TBNF Terminal Base Wiring for the 1794-OA8
Connecting Wiring for the 1794-OA8I
1. For 1794-TB2, 1794-TB3, or 1794-TB3S: Connect individual output wiring to
the even numbered terminals on the 0…15 row (A).
For 1794-TBN or 1794-TBNF: Connect individual output wiring to the
even numbered terminals on the 16…33 row (B).
2. For 1794-TB2, 1794-TB3, or 1794-TB3S: Connect the associated V AC
power lead (L1) to the corresponding odd numbered terminal on the
0…15 row (A) for each output as indicated in the table below.
For 1794-TBN or 1794-TBNF: Connect the associated V AC power (L1)
lead to the odd numbered terminals on row (C).

1794-TBN and 1794-TBNF Terminal Base Wiring for the 1794-OA8I
Connecting 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
table below.
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 V AC
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 table
below. (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
Individual isolated 120V AC common (L2) leads must be run externally to each
output device.
