1794-TB3 and -TB3S Terminal Base Wiring for the
1794-IB10XOB6
2 and 3-Wire Input Wiring for 1794-IB10XOB6
Connecting Wiring for the 1794-IB16XOB16P
1. Connect individual input wiring (IN0 to IN15) to numbered terminals
on the 0-15 row (A) as indicated in the table below.
2. Connect the associated power to the +V1 terminal (35, 37, 39 or 41)
on the 34-51 row (C) as indicated in the table below.
3. Connect the associated common (-V1) for IN0 to IN15 to COM1
(terminal 36, 38, 40 or 42) on the 34-51 row (C).
4. Connect individual output wiring (OUT0 to OUT15) to terminals 17
thru 32 on the 16-33 row (B) as indicated in the table below. (Note:
Do not connect to terminals 16 or 33.)
5. Connect the associated power to the +V2 terminal (43, 45, 47 or 49)
on the 34-51 row (C) as indicated in the table below.
6. Connect the associated common (-V2) for OUT0 to OUT15 to
COM2 (terminal 44, 46, 48 or 50) on the 34-51 row (C).
7. If continuing input wiring to the next terminal base unit, connect a
jumper from terminal 41(+V1) to the power terminal on the next base
unit; connect a jumper from terminal 42 (COM1) to the common
terminal on the next base unit.
8. If continuing output wiring to the next terminal base unit, connect a
jumper from terminal 49 (+V2) to the power terminal on the next
base unit; connect a jumper from terminal 50 (COM2) to the common
terminal on the next base unit.
