POINT I/O™ 5V and 24V Encoder/Counter 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.
POINT I/O™ 5V and 24V Encoder/Counter 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 publication 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 Publication 11.
POINT I/O™ 5V and 24V Encoder/Counter 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.
POINT I/O™ 5V and 24V Encoder/Counter Modules 5 European Hazardous Location Approval European Zone 2 Certification. (The following applies when the product bears the EEx Marking) This equipment is intended for use in potentially explosive atmospheres as defined by European Union Directive 94/9/EC.
POINT I/O™ 5V and 24V Encoder/Counter Modules Before You Begin You can use these Series C POINT I/O Encoder/Counter modules with DeviceNet and PROFIBUS adapters. If you are using RSLogix 5000 software, version 11 or higher, you can also use the Series C modules with ControlNet and Ethernet adapters. Use this diagram to identify the external features of the module.
POINT I/O™ 5V and 24V Encoder/Counter Modules 7 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. 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.
POINT I/O™ 5V and 24V Encoder/Counter Modules 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.
POINT I/O™ 5V and 24V Encoder/Counter Modules 9 Install the Removable Terminal Block A removable terminal block (RTB) is supplied with your wiring base assembly. To remove, pull up the RTB handle. This allows the mounting base to be removed and replaced 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.
POINT I/O™ 5V and 24V Encoder/Counter Modules Wire the Module 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.

POINT I/O™ 5V and 24V Encoder/Counter Modules Communicate with Your Module POINT I/O modules send (consume) and receive (produce) I/O messages. You map these messages into the processor’s memory. These modules produce 6 or 10 Bytes of input data (scanner Rx) (status). These modules consume 1 Byte of I/O data (scanner Tx). Use parameters 11 and 12 to select assembly 101, 102, or 103 for data produced by the modules.
