POINT I/O 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.
POINT I/O Input Modules 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.
POINT I/O Input Modules 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. Each product is supplied with markings on the rating nameplate indicating the hazardous location temperature code.
POINT I/O Input Modules 5 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.
POINT I/O Input Modules Before You Begin You can use these Series C POINT I/O™ Input Modules with DeviceNet and PROFIBUS adapters. If you are using RSLogix 5000 software, version 11 or higher, you can also use the modules with ControlNet and Ethernet adapters. Use this diagram to identify the external features of the module.
POINT I/O Input Modules 7 About the Module The POINT I/O sink input modules are available in two-input, four-input, and eight-input options. They install on mounting bases that mount on a DIN rail. All wiring is made to a Removable Terminal Block (RTB) mounted on the mounting base. Install the Mounting Base To install the mounting base on the DIN rail, proceed as follows: ATTENTION: This product is grounded through the DIN rail to chassis ground.
POINT I/O Input Modules Install the Module The module can be installed before or after base installation. Make sure that the mounting base is correctly keyed before installing the module into the mounting base. In addition, make sure the mounting base locking screw is positioned horizontal referenced to the base. 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.
POINT I/O Input Modules 9 Install the Removable Terminal Block A Removable Terminal Block (RTB) is supplied with your wiring base assembly. This allows the mounting base to be removed and replaced as necessary without removing any of the wiring. To insert 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.
POINT I/O Input Modules Remove a Mounting Base To remove a mounting base, you must remove any installed module, and the module installed in the base to the right. Remove the Removable Terminal Block, if wired. 1. Unlatch the RTB handle on the I/O module. 2. Pull on the RTB handle to remove the Removable Terminal Block. 3. Press on the module lock on the top of the module. 4. Pull on the I/O module to remove from the base. 5. Repeat steps 1, 2, 3 and 4 for the module to the right. 6.
POINT I/O Input Modules 11 Communicate with Your Module I/O messages are sent to (consumed) and received from (produced) the POINT I/O modules. These messages are mapped into the processor’s memory. This POINT I/O input module produces 1 Byte of input data (scanner Rx). It does not consume I/O data (scanner Tx).

POINT I/O Input Modules 13 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. WARNING: To comply with the CE Low Voltage Directive (LVD), this equipment must be powered from a source compliant with the following: Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
