Connect Wiring for the 1794-IC16 or 1794-OC16
1. Connect individual input (1794-IC16) or output (1794-OC16) wiring to
numbered terminals on the 0…15 row (A) as indicated in the Wiring
Connections for 1794-IC16 and 1794-OC16 table.
2.
1794-IC16
– Connect the assoV DC power lead of the input device to
the corresponding terminal on the 34…51 row (C) for each input as indicated in
the Wiring Connections for 1794-IC16 and 1794-OC16 table. The +V DC
power terminals of row (C) are internally connected together.
3.
1794-OC16
– Connect the associated V DC common lead of the output device
to the corresponding terminal on the 16…33 row (B) for each output as indicated
in the Wiring Connections for 1794-IC16 and 1794-OC16 table. The V DC
common terminals of row (B) are internally connected together.
4.
1794-IC16 only
– Connect the associated input common (3-wire devices only)
to the corresponding terminal on the 16…33 row (B) for each input as indicated
in the Wiring Connections for 1794-IC16 and 1794-OC16 table. Commons are
internally connected together.
5. CV DC power to terminal 34 on the 34…51 row (C).
6. Connect V DC common to terminal 16 on the 16…33 row (B).
7. If daisychaining power to the next terminal base, connect a jumper from terminal
51 (+V DC) on this base unit to terminal 34 on the next base unit.
8. If continuing V DC common to the next base unit, connect a jumper from
terminal 33 (common) on this base unit to terminal 16 on the next base unit.
