Important User Information
Solid state equipment has operational characteristics differing from those of electromechanical
equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls
(Publication SGI-1.1 available from your local Rockwell Automation sales office or online at
http://www.ab.com/manuals/gi) describes some important differences between solid state equipment
and hard-wired electromechanical devices. Because of this difference, and also because of the wide
variety of uses for solid state equipment, all persons responsible for applying this equipment must
satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages
resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the
many variables and requirements associated with any particular installation, Rockwell Automation, Inc.
cannot assume responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits,
equipment, or software described in this manual.

Environment and Enclosure
Prevent Electrostatic Discharge
ATTENTION 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.
NOTE: See NEMA Standards publication 250 and IEC publication 60529, as applicable,
for explanations of the degrees of protection provided by different types of enclosure.
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.
ATTENTION 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, store the equipment in appropriate static-safe packaging.

Removal and Insertion Under Power
Be sure that power is removed or the area is nonhazardous before
proceeding. Repeated electrical arcing causes excessive wear to
contacts on both the module and its mating connector. Worn contacts
may create electrical resistance that can affect module operation.

WARNING When you insert or remove the module while backplane
power is on, an electrical arc can occur. This could cause
an explosion in hazardous location installations.

Identify the Module Components
You received the following components with your order:
•1756-IH16ISOE module
•Removable Terminal Block (RTB) door label
•jumper bar
If you did not receive these components, contact your local
distributor Rockwell Automation sales office.
This module mounts in a 1756 chassis and uses a separately-ordered
RTB or a Bulletin 1492 Interface Module (IFM)(1) to connect all
field-side wiring. This module uses one of the following RTBs:
•1756-TBCH 36 position Cage clamp RTB
•1756-TBS6H 36 position Spring clamp RTB
Use an extended-depth cover (1756-TBE) for applications with heavy
gauge wiring or requiring additional routing space. When using an
IFM, consult the documentation that came with it to connect wiring.
Note the Power Requirements
This module receives power from the 1756 chassis power supply and
requires 2 sources of power from the ControlLogix backplane:
•275mA at 5.1V dc
•2mA at 24V dc
Add this current/power value (1.3W) to the requirements of all other
modules in the chassis to prevent overloading the power supply.
(1) The ControlLogix system has been agency certified using only the ControlLogix RTBs (i.e. 1756-TBCH,
1756-TBNH 1756-TBSH and 1756-TBS6H). Any application that requires agency certification of the
ControlLogix system using other wiring termination methods may require application specific approval
by the certifying agency.
IMPORTANT Before you install your module, you should:
•install and ground a 1756 chassis and power supply.
•order and receive an RTB or IFM, and its
components, for your application.

Publication 1756-IN592A-EN-P - March 2004
Install the Module
You can install or remove the module while chassis power is applied.
Be sure that power is removed or the area is nonhazardous before
proceeding. Repeated electrical arcing causes excessive wear to
contacts on both the module and its mating connector. Worn contacts
may create electrical resistance that can affect module operation.
1. Align the circuit board with the top and bottom chassis guides.
2. Slide the module into chassis until module locking tabs click.
WARNING When you insert or remove the module while backplane
power is on, an electrical arc can occur. This could cause
an explosion in hazardous location installations.

Key the Module and Removable Terminal Block/Interface Module
Use the wedge-shaped keying tabs and U-shaped keying bands to
prevent connecting the wrong wires to your module.
Key positions on the module that correspond to unkeyed positions
on the RTB. For example, if you key the first position on the module,
leave the first position on the RTB unkeyed.
1. To key the module, insert the U-shaped band, as shown.
2. Push the band until it snaps in place.
3. To key the RTB or IFM, insert the wedge-shaped tab with
rounded edge first, as shown.
4. Push the tab until it stops.
Reposition the tabs to rekey future module applications.

Wire the 1756-IH16ISOE Module
You can only connect wiring to your module with an RTB or IFM.
After completing field-side wiring, secure the wires in the strain relief
area with a cable-tie.
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. All terminals with the same name are connected together on the module. For
example, DC (-) can be connected to either terminal marked GND-15.
2. When you use the second GND-15 terminal to daisy chain to other RTBs, always
connect the daisy chain to the terminal directly connected to the supply wire, as
shown in the example above.
3. If separate power sources are used, do not exceed the specified isolation voltage.
4. Do not connect more than 2 wires to any single terminal.
