Publication 1794-IN096B-EN-P - February 2004
Installing Your Digital Input or Output Module
The input module mounts on a 1794-TB32 or -TB32S terminal base. The
output module mounts on a 1794-TB2, -TB3 or -TB3S terminal base.
1. Rotate the keyswitch (1) on the terminal base (2) clockwise to position
2 as required for this type of module.
2. Make certain the flexbus connector (3) is pushed all the way to the left
to connect with the neighboring termbase/adapter. You cannot install
the module unless the connector is fully extended.
3. Make sure the pins on the bottom of the module are straight so they
will align properly with the connector in the terminal base.
4. Position the module (4) with its alignment bar (5) aligned with the
groove (6) on the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit.
The module is seated when the latching mechanism (7) is locked into
the module.
Connecting Wiring for the 1794-IB16D (using 1794-TB32 or -TB32S
terminal base)
1. Connect individual input wiring (IN00-IN15) to terminals 0 thru 15
on the 0-15 row (A) as indicated in the table below.
2. Connect individual Sensor Power wiring (sensor power 0 thru 15) to
terminals 17 thru 32 on the 16-33 row (B) as indicated in the table
below. Do not connect to terminals 16 or 33.
3. Connect the associated +V2 dc power lead of the input device to the
corresponding terminal on the 34-51 row (C) for each input as
indicated in the table below. (The +V2 power terminals of row (C) are
internally connected together.)
4. Connect the associated input common (3-wire devices only) to the
corresponding terminal on the 34-51 row. (C) for each input as
indicated in the table below. (Commons are internally connected
together.)
5. Connect +V dc power to pin 43 (+V) on the 34-51 row (C).
6. Connect -V dc common to pin 44 (COM2) on the 34-51 row (C).
7. If daisychaining input wiring power to the next terminal base, connect
a jumper from terminal 49 (+V dc) on this base unit to the power
terminal on the next base unit (refer to the installation instructions for
the next terminal base unit).
8. If continuing input wiring common to the next base unit, connect a
jumper from terminal 50 (common) on this base unit to the common
terminal on the next base unit (refer to the installation instructions for
the next terminal base unit).
1794-TB32 and -TB32S Terminal Base Wiring for the
1794-IB16D
Wiring for 1794-IB16D (use with 1794-TB32 or -TB32S terminal
base units)
Connecting Wiring for the 1794-OB16D (using 1794-TB2, -TB3 or
-TB3S terminal base)
1. Connect individual output wiring to numbered terminals on the 0-15
row (A) as indicated in the table below.
2. Connect the associated common for each output to the corresponding
terminal on the 16-33 row (B) as indicated in the table below. (The
common terminals of row (B) are internally connected together.)
3. Connect +V dc power to terminal 34 on the 34-51 row (C). (The
power terminals of row (C) are internally connected together.)
4. Connect dc common (COM) to terminal 16 on the 16-33 row (B).
5. 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.
ATTENTION
During mounting of all devices, be sure that all
debris (metal chips, wire strands, etc.) is kept from
falling into the module. Debris that falls into the
module could cause damage on power up.
