FLEX I/O 240V AC Digital Input and Output Modules
Publication 1794-IN123D-EN-P - August 2018
Connect Wiring for your 1794-OM16 Module
(using a 1794-TBN or TBNF Terminal Base)
1. Connect individual output wiring to terminals 0...15 on the 16-33 row (B), and
the 34-51 row (C) as indicated in the Wiring Connections for 1794-IM16 and
1794-OM16 table.
2. 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 240V AC power L1 to terminal 34 on the 34-51 row (C).
4. Connect 240V 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 (240V AC L1) on this base unit to terminal 34 on the next base unit.
6. If continuing 240V AC common (L2) to the next base unit, connect a jumper
from terminal 33 (240V AC common L2) on this base unit to terminal 16 on the
next base unit.
Note:
Total current draw through terminal base connection is limited to 10 A. Separate
power connections to each terminal base may be necessary.
