Page 2: Important User Information
2 POINT I/O RTD and Isolated Thermocouple Input Modules 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.rockwellautomation.com/literature/) describes some important differences between solid-state equipment and hard-wired electromechanical devices.
Page 3: Environment And Enclosure
POINT I/O RTD and Isolated Thermocouple Input Modules Environment and Enclosure 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), and at altitudes of up to 2000 m (6562 ft) without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR 11.
Page 4: North American Hazardous Location Approval
4 POINT I/O RTD and Isolated Thermocouple Input Modules ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc-plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail materials (for example, aluminum, plastic) that can corrode, oxidize, or are poor conductors can result in improper or intermittent grounding.
Page 5: European Hazardous Location Approval
POINT I/O RTD and Isolated Thermocouple Input Modules European Hazardous Location Approval The following applies when the product bears the Ex Marking This equipment is intended for use in potentially explosive atmospheres as defined by European Union Directive 94/9/EC. DEMKO certifies that this equipment has been found to comply with the Essential Health and Safety Requirements relating to the design and construction of Category 3 equipment intended for use in Zone 2 potentially explosive atmospheres, given in Annex II to this Directive.

Page 8: Install The Mounting Base
8 POINT I/O RTD and Isolated Thermocouple Input Modules Install the Mounting Base To install the mounting base on the DIN rail, proceed as follows: 1. Position the mounting base vertically above the installed units (adapter, power supply, or existing module). Slide the mounting base until the interlocking side pieces engage the adjacent module or adapter.
Page 9: Install The Module
POINT I/O RTD and Isolated Thermocouple Input Modules ATTENTION: 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.

10 POINT I/O RTD and Isolated Thermocouple Input Modules 1. Using a bladed screwdriver, rotate the keyswitch on the mounting base clockwise until the number required for the type of module being installed aligns with the notch in the base. 2.
Page 11 POINT I/O RTD and Isolated Thermocouple Input Modules 3. If an I/O module is installed, snap the RTB handle into place on the module. Insert the module straight down into the mounting base. Hook the RTB end into the mounting base end and rotate until it locks into place.
Page 12: Wire The Module
12 POINT I/O RTD and Isolated Thermocouple Input Modules Wire the Module To wire the module, refer to the diagrams and tables. 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.

Page 15: Communicate With The Module
POINT I/O RTD and Isolated Thermocouple Input Modules Communicate with the Module POINT I/O modules send (produce) and receive (consume) I/O data (messages). You map this data into the processor’s memory. The 1734-IR2 and 1734-IR2E modules produce 6 bytes of input data (scanner Rx) and fault status data.
