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://literature.rockwellautomation.com) 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.

Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell Automation, Inc., is prohibited.

Throughout this manual, when necessary, we use notes to make you aware of safety considerations.

POINT I/O 2 Current and 2 Voltage Input Analog Modules 3

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 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

Preventing Electrostatic Discharge

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.

Before You Begin

Read this manual for information about how to install the following modules.

•1734-IE2C, Series C, POINT I/O Current Input Analog Module

•1734-IE2V, Series C, POINT I/O Voltage Input Analog Module

You can use these Series C modules with DeviceNet and PROFIBUS adapters. If you are using RSLogix 5000 software version 11 or higher, you can also use these Series C modules with ControlNet and Ethernet adapters.

6 POINT I/O 2 Current and 2 Voltage Input Analog Modules

Install the Mounting Base

To install the mounting base on the DIN rail, proceed as follows.

ATTENTION

POINT I/O is grounded through the DIN rail to chassis ground. Use zinc-plated, yellow-chromated steel DIN rail to assure proper grounding. The use of DIN rail materials (e.g., aluminum, plastic, etc.) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding. Secure DIN rail to mounting surface approximately every 200 mm.

1.Position the mounting base vertically above the installed units (adapter, power supply, or existing module).

2.Slide the mounting base down so that the interlocking side pieces engage the adjacent module or adapter.

3.Press firmly to seat the mounting base on the DIN rail.

The mounting base will snap into place.

ATTENTION

Do not discard the end cap shipped with an adapter or communication interface module. Use this end cap to cover the exposed

interconnections on the last mounting base on the DIN rail.

Failure to do so could result in equipment damage or injury from electric shock.

POINT I/O 2 Current and 2 Voltage Input Analog Modules 7

Install the Module

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.

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.

Install the module before or after base installation. Make sure that you:

•correctly keyed the mounting base before installing the module into the mounting base

•positioned the mounting base locking screw horizontal with reference to the base

To install the module, proceed as follows.

1.Using a bladed screwdriver, rotate the keyswitch on the mounting base clockwise until the number required for the type of module you are installing aligns with the notch in the base.

2.Make certain the DIN rail locking screw is in the horizontal position.

You cannot insert the module if the locking mechanism is unlocked.

3.Insert the module straight down into the mounting base and press to secure.

The module will lock into place.

8 POINT I/O 2 Current and 2 Voltage Input Analog Modules

Install the Removable Terminal Block (RTB)

A removable terminal block comes with your wiring base assembly. To remove, pull up on the RTB handle. You can now remove the mounting base and replace as necessary without removing any of the wiring.

To reinsert the removable terminal block, proceed as follows.

1.Insert the end opposite the handle into the base unit.

This end has a curved section that engages with the wiring base.

2.Rotate the terminal block into the wiring base until it locks itself in place.

3.If an I/O module is installed, snap the RTB handle into place on the module.

WARNING

When you connect or disconnect the removable terminal block (RTB) with field-side power applied, 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.
