FLEX I/O 8 Input HART Analog Module 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.
FLEX I/O 8 Input HART Analog Module 3 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 60664-1), at altitudes up to 2000 m (6562 ft) without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR 11.
FLEX I/O 8 Input HART Analog Module 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 or plastic) 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 (7.8 in.) and use end-anchors appropriately.
FLEX I/O 8 Input HART Analog Module 5 North American Hazardous Location Approval The following information applies when operating this equipment in hazardous locations: Informations sur l’utilisation de cet équipement en environnements dangereux: Products marked "CL I, DIV 2, GP A, B, C, D" are suitable for use in Class I Division 2 Groups A, B, C, D, Hazardous Locations and nonhazardous locations only.

FLEX I/O 8 Input HART Analog Module 7 About the Module The HART analog modules can be used with ControlNet, Ethernet and Profibus-DP (1794-APBDV1 only) adapters. When using the Series B module with a Series B profile, you must have a ControlNet adapter Revision 5.1 or higher or an Ethernet adapater Revision 4.2 or higher. For this scenario (Series A profile with a Series B Module), the data maps (input, configuration and extended configuration) are designated as Series A Mode.
FLEX I/O 8 Input HART Analog Module ATTENTION IMPORTANT Do not remove or replace a Terminal Base unit while power is applied. Interruption of the backplane can result in unintentional operation or machine motion. You must disable keying in your profile when replacing a series A module with a series B module. To install the module on a 1794 terminal base, refer to the figure and complete the following. 1.
FLEX I/O 8 Input HART Analog Module 9 Wire the Module 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. WARNING To connect two-wire transmitter devices for 1794-TB3G and 1794-TB3GS bases, refer to the tables and figure and complete the following.
FLEX I/O 8 Input HART Analog Module 3. Refer to the Figure for other configurations. 4. Connect +V DC power to terminal 34 on the 34 to 51 row (C). 5. Connect -V to terminal 35 on the 34 to 51 row (C). 6. If continuing power to the next terminal base unit, connect a jumper from terminal 50 (+V) on this base unit to terminal 34 on the next base unit. If continuing common to the next terminal base unit, connect a jumper from terminal 51 (-V) on this base unit to terminal 35 on the next base unit.
FLEX I/O 8 Input HART Analog Module 11 Ground the Module All I/O wiring must use shielded wire. Shields must be terminated external to the module, such as bus bars and shield-terminating feed-throughs. 44862 Inputs Each input can be operated from an analog field device signal. The channels in these modules are electrically connected to each other and have a common plus-line. When interconnecting several lines, you must consider the total accumulated power.
