High-Speed Counter 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://www.ab.com/manuals/gi) describes some important differences between solid state equipment and hard-wired electromechanical devices.

High-Speed Counter Module Hazardous Location Considerations This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D or non-hazardous locations only. The following WARNING statement applies to use in hazardous locations. WARNING EXPLOSION HAZARD • Substitution of components may impair suitability for Class I, Division 2. • Do not replace components or disconnect equipment unless power has been switched off or the area is known to be non-hazardous.
High-Speed Counter Module 5 High-Speed Counter Module Overview The High-Speed Counter Module, Catalog Number 1746-HSCE is an SLC 500 family compatible device except with the 1747-ASB Remote I/O Adapter Module. It can be used with SLC™ 5/02 (and above) processors. The module’s bidirectional counting ability allows it to detect movement in either direction. In addition, x2 and x4 counting modes are provided to fully use the capabilities of high-resolution quadrature encoders.

High-Speed Counter Module 7 Default settings are shown below: O N 1 234 SW 2 SW 2 JW 1 JW 1 SW2 Default 10 to 30V dc 3 JW1 1 JW1 Default 10 ms filter O N 1234 SW 1 SW1 Default Single-ended ATTENTION Use a small screwdriver to change dip switch positions. Graphite from pencils will damage the switch.
High-Speed Counter Module SW2 Settings Select an output voltage range that coincides with your supply voltage. The selections are 4.5 to 10V dc or 10 to 30V dc. ON OFF 1234 10 to 30V dc 1234 ON OFF Switch 1 2 3 4 Output 0 1 2 3 4.5 to 10V dc All switches of SW2 must be ON or all switches must be OFF. Permanent damage may result if some are ON and some are OFF. ATTENTION Operating in the 10 to 30V dc range with the switches set for the 4.5 to 10V dc range damages the module.
High-Speed Counter Module 9 JW1 Settings Select 300 µs or 10 ms filtering to debounce the limit switch input. Position the jumper as follows: 321 32 1 JW 1 JW 1 10 ms filter 300 µs filter The LS input allows you to make a direct connection to nominal voltage levels of 5, 12, or 24V dc. The ON voltage ranges are as follows: Wiring Terminal ON Range LS (24V dc) 16.5 to 30V dc LS (12V dc) 9.4 to 16.5V dc LS (5V dc) 3.8 to 5.5V dc See page 19 for limit switch wiring instructions.
High-Speed Counter Module Install the Module Installation procedures for this module are the same as for any other discrete I/O or specialty module. IMPORTANT Set the dip switches before installing the module. ATTENTION Disconnect power before attempting to install, remove, or wire the module. Make sure your SLC power supply has adequate reserve current capacity. The module requires 320 mA at 5V dc. Top and Bottom Module Release(s) Card Guide 1.
High-Speed Counter Module 11 Remove the Terminal Block The removable terminal wiring block eliminates the need to rewire a module if it is removed from the chassis. Each terminal accepts two #14 AWG wires. ATTENTION Disconnect power before attempting to install, remove, or wire the removable terminal wiring block. To avoid cracking the removable terminal block, alternate the removal of the slotted terminal block release screws.
High-Speed Counter Module Important Wiring Considerations Use the following guidelines when planning the system wiring for the module: • • • • • • • • Install the SLC 500 system in a NEMA-rated enclosure. Disconnect power to the SLC processor and the module before wiring. Make sure the SLC 500 system is properly grounded. Group this module and low-voltage DC modules away from AC I/O or high-voltage DC modules. Shielded cable is required for high-speed input signals A, B, and Z.
High-Speed Counter Module 13 Input and Output Connections Input and output wiring terminals are located on the front of the module, behind the terminal cover. When you connect input and output devices, you must also be concerned with the settings of dip switch SW1 (input connections), dip switch SW2 (output connections), and jumper JW1 (limit switch input connections). The location and description of these are shown on pages 6 through 9. OUTPUT 0 1 2 3 Upper Retaining Screw Maximum Torque = 0.7 to 0.
High-Speed Counter Module Outputs The module features four physical outputs. They can be controlled by the module when certain counter conditions are met, or they can be controlled from the user program (refer to the High-Speed Counter Module User Manual, publication 1746-6.5 for M0:e.0 information). The outputs are bipolar transistors connected in a sinking (open collector sinking) configuration. When the output is energized, it sinks the current. Do not use incandescent lamps as output indicators.
