2 POINT I/O 2 Current and 2 Voltage Input Analog ModulesImportant User InformationSolid state equipment has operational characteristics differing from those ofelectromechanical equipment. Safety Guidelines for the Application, Installation andMaintenance of Solid State Controls (Publication SGI-1.1 available from your local RockwellAutomation sales office or online at http://literature.rockwellautomation.com) describessome important differences between solid state equipment and hard-wiredelectromechanical devices. Because of this difference, and also because of the wide varietyof uses for solid state equipment, all persons responsible for applying this equipment mustsatisfy themselves that each intended application of this equipment is acceptable.In no event will Rockwell Automation, Inc. be responsible or liable for indirect orconsequential 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 onthe examples and diagrams.No patent liability is assumed by Rockwell Automation, Inc. with respect to use ofinformation, circuits, equipment, or software described in this manual.Reproduction of the contents of this manual, in whole or in part, without written permissionof Rockwell Automation, Inc., is prohibited.Throughout this manual, when necessary, we use notes to make you aware of tifies information about practices or circumstances that can cause an explosion in ahazardous environment, which may lead to personal injury or death, property damage, oreconomic loss.Identifies information that is critical for successful application and understanding of theproduct.Identifies information about practices or circumstances that can lead to personal injury ordeath, property damage, or economic loss.

POINT I/O 2 Current and 2 Voltage Input Analog Modules 3ATTENTIONEnvironment and EnclosureThis equipment is intended for use in a PollutionDegree 2 industrial environment, in overvoltageCategory II applications (as defined in IECpublication 60664-1), at altitudes up to 2000 meterswithout derating.This equipment is considered Group 1, Class Aindustrial equipment according to IEC/CISPRPublication 11. Without appropriate precautions,there may be potential difficulties ensuringelectromagnetic compatibility in other environmentsdue to conducted as well as radiated disturbance.This equipment is supplied as “open type”equipment. It must be mounted within an enclosurethat is suitably designed for those specificenvironmental conditions that will be present andappropriately designed to prevent personal injuryresulting from accessibility to live parts. The interiorof the enclosure must be accessible only by the useof a tool. Subsequent sections of this publicationmay contain additional information regardingspecific enclosure type ratings that are required tocomply with certain product safety certifications.See NEMA Standards publication 250 and IECpublication 60529, as applicable, for explanations ofthe degrees of protection provided by differenttypes of enclosure. Also, see the appropriatesections in this publication, as well as theAllen-Bradley publication 1770-4.1 (“IndustrialAutomation Wiring and Grounding Guidelines”), foradditional installation requirements pertaining tothis equipment.Publication 1734-IN027A-EN-E - May 2005

4 POINT I/O 2 Current and 2 Voltage Input Analog ModulesATTENTIONPreventing Electrostatic DischargeThis equipment is sensitive to electrostaticdischarge, which can cause internal damage andaffect normal operation. Follow these guidelineswhen you handle this equipment: Touch a grounded object to dischargepotential static. Wear an approved grounding wriststrap. Do not touch connectors or pins oncomponent boards. Do not touch circuit components inside theequipment. If available, use a static-safe workstation. When not in use, store the equipment inappropriate static-safe packaging.Before You BeginRead this manual for information about how to install the followingmodules. 1734-IE2C, Series C, POINT I/O Current Input Analog Module 1734-IE2V, Series C, POINT I/O Voltage Input Analog ModuleYou can use these Series C modules with DeviceNet and PROFIBUSadapters. If you are using RSLogix 5000 software version 11 or higher,you can also use these Series C modules with ControlNet andEthernet adapters.Publication 1734-IN027A-EN-E - May 2005

6 POINT I/O 2 Current and 2 Voltage Input Analog ModulesInstall the Mounting BaseTo install the mounting base on the DIN rail, proceed as follows.ATTENTIONPOINT I/O is grounded through the DIN rail tochassis ground. Use zinc-plated, yellow-chromatedsteel DIN rail to assure proper grounding. The useof 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 approximatelyevery 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 sidepieces 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.ATTENTIONDo not discard the end cap shipped with anadapter or communication interface module.Use this end cap to cover the exposedinterconnections on the last mounting base on theDIN rail.Failure to do so could result in equipment damageor injury from electric shock.Publication 1734-IN027A-EN-E - May 2005

POINT I/O 2 Current and 2 Voltage Input Analog Modules 7Install the ModuleWARNINGWhen you insert or remove the module whilebackplane power is on, an electrical arc can occur.This could cause an explosion in hazardouslocation installations.Be sure that power is removed or the area isnonhazardous before proceeding. Repeatedelectrical arcing causes excessive wear to contactson both the module and its mating connector. Worncontacts may create electrical resistance that canaffect module operation.Install the module before or after base installation. Make sure thatyou: correctly keyed the mounting base before installing themodule into the mounting base positioned the mounting base locking screw horizontal withreference to the baseTo install the module, proceed as follows.1. Using a bladed screwdriver, rotate the keyswitch on themounting base clockwise until the number required for thetype of module you are installing aligns with the notch in thebase.2. Make certain the DIN rail locking screw is in the horizontalposition.You cannot insert the module if the locking mechanism isunlocked.3. Insert the module straight down into the mounting base andpress to secure.The module will lock into place.Publication 1734-IN027A-EN-E - May 2005

8 POINT I/O 2 Current and 2 Voltage Input Analog ModulesInstall 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 themounting base and replace as necessary without removing any of thewiring.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 wiringbase.2. Rotate the terminal block into the wiring base until it locksitself in place.3. If an I/O module is installed, snap the RTB handle into placeon the module.WARNINGWhen you connect or disconnect the removableterminal block (RTB) with field-side powerapplied, an electrical arc can occur. This couldcause an explosion in hazardous locationinstallations.Be sure that power is removed or the area isnonhazardous before proceeding.Publication 1734-IN027A-EN-E - May 2005

Unlatch the RTB handle on the I/O module.2. Pull on the RTB handle to remove the removable terminalblock.WARNINGWhen you connect or disconnect the removableterminal block (RTB) with field-side powerapplied, an electrical arc can occur. This couldcause an explosion in hazardous locationinstallations.Be sure that power is removed or the area isnonhazardous before proceeding.3. Press on the module lock on the top of the module.4. Pull on the I/O module to remove from the base.WARNINGWhen you insert or remove the module whilebackplane power is on, an electrical arc can occur.This could cause an explosion in hazardouslocation installations.Be sure that power is removed or the area isnonhazardous before proceeding. Repeatedelectrical arcing causes excessive wear to contactson both the module and its mating connector. Worncontacts may create electrical resistance that canaffect module operation.5. Repeat steps 1, 2, 3, and 4 for the module to the right.Publication 1734-IN027A-EN-E - May 2005
