This module mounts on a 1794 terminal base unit.

1. Rotate keyswitch (1) on terminal base unit (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 terminal base/adapter. You cannot

install the module unless the connector is fully extended.

3. Make sure that the pins on the bottom of the module are straight so

they will align properly with the connector in the terminal base unit.

WARNING

If you remove or insert the module while the

backplane power is on, an electrical arc can occur.

This could cause an explosion in hazardous location

installations. Be sure that power is removed or the

area is nonhazardous before proceeding.

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.

property liability) for actual use based upon the examples shown in this publication.

Allen–Bradley publication SGI–1.1, Safety Guidelines for Application, Installation,

and Maintenance of Solid–State Control (available from your local Allen–Bradley

office), describes some important differences between solid–state equipment and

electromechanical devices that should be taken into consideration when applying

products such as those described in this publication.

ATTENTION

Identifies information about practices or

circumstances that can lead to personal injury or

death, property damage, or economic loss.

ATTENTION

Environment and Enclosure

This equipment is intended for use in a Pollution Degree 2

industrial environment, in overvoltage Category II

applications (as defined in IEC publication 60664–1), at

altitudes up to 2000 meters without derating.

This equipment is considered Group 1, Class A industrial

equipment according to IEC/CISPR Publication 11.

Without appropriate precautions, there may be potential

difficulties ensuring electromagnetic compatibility in other

environments due to conducted as well as radiated

disturbance.

This equipment is supplied as “open type” equipment. It

must be mounted within an enclosure that is suitably

designed for those specific environmental conditions that

will be present, and appropriately designed to prevent

personal injury resulting from accessibility to live parts.

The interior of the enclosure must be accessible only by

the use of a tool. Subsequent sections of this publication

may contain additional information regarding specific

enclosure type ratings that are required to comply with

certain product safety certifications.

See NEMA Standards publication 250 and IEC publication

60529, as applicable, for explanations of the degrees of

protection provided by different types of enclosures. Also,

see the appropriate sections in this publication, as well as

the Allen–Bradley publication 1770–4.1, (“Industrial

Automation Wiring and Grounding Guidelines”), for

additional installation requirements pertaining to this

equipment.

This equipment is sensitive to electrostatic discharge,

which can cause internal damage and affect normal

operation. Follow these guidelines when you handle

this equipment:

• Touch a grounded object to discharge potential

static.

• Wear an approved grounding wriststrap.

• Do not touch connectors or pins on component

boards.

• Do not touch circuit components inside the

equipment.

• If available, use a static–safe workstation.

• When not in use, keep modules in appropriate

static–safe packaging.

ATTENTION

Remove field-side power before removing or

inserting this module. This module is designed so

you can remove and insert it under backplane

power. When you remove or insert a module with

field-side power applied, an electrical arc may occur.

An electrical arc can cause personal injury or

property damage by:

• sending an erroneous signal to your system’s field

devices causing unintended machine motion

• causing an explosion in a hazardous environment

Repeated electrical arcing causes excessive wear to

contacts on both the module and its mating

connector. Worn contacts may create electrical

resistance.

Wiring to a 1794ĆTB3 or ĆTB3S Terminal Base Unit

WARNING

If you connect or disconnect wiring while the field

side power is on, an electrical arc can occur. This

could cause an explosion in hazardous location

installations. Be sure that power is removed or the

area is nonhazardous before proceeding.

1. Connect individual input wiring to numbered terminals on the 0–15

row (A) as indicated in the table below.

2. Connect the associated +V 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 +V dc power terminals of row (C)

are internally connected together.)

3. 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 table below. (Commons are internally connected

together.)

4. Connect +V dc power to terminal 34 on the 34–51 row (C).

5. Connect dc return to terminal 16 on the 16–33 row (B).

6. If continuing power to the next terminal base unit, connect a jumper

from terminal 51 (+V dc) on this base unit to terminal 34 on the next

base unit.

7. If continuing common to the next terminal base unit, connect a jumper

from terminal 33 (common) on this base unit to terminal 16 on the

next base unit.

Setting the Input Filter Time

You can select the input filter time (FT) for each group of channels (channels 00

through 11, or channels 12 through 15). Select the input filter time by setting the

corresponding bits in the output image table (complementary word) for

the module.

For example, to set a filter time of 4ms for a dc input module at address

rack 1, module group 0, set bits 05, 04, 03, 02, 01, and 00 as shown

below.
