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. Because of this difference, and also because of the wide variety of
uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves
that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages
resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many
variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot
assume responsibility or liability for actual use based on the examples and diagrams.

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.
• Do not connect or disconnect components unless power
has been switched off or the area is known to be
non-hazardous.
• All wiring must comply with N.E.C. article 501-4(b).
Environnements dangereux
Cet équipement est conçu pour être utilisé dans des environnements de Classe I,
Division 2, Groupes A, B, C, D ou non dangereux. La mise en garde suivante
s’applique à une utilisation dans des environnements dangereux.
AVERTISSEMENT
DANGER D’EXPLOSION
• La substitution de composants peut rendre cet équipement
impropre à une utilisation en environnement de Classe I,
Division 2.
• Ne pas remplacer de composants ou déconnecter
l'équipement sans s'être assuré que l'alimentation est
coupée.
• Ne pas connecter ou déconnecter des composants sans
s'être assuré que l'alimentation est coupée.

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 inputs from quadrature encoders and various high-speed switches are
supported. Accepting input pulse frequencies of up to 50k Hz allows precise
control of fast motions.
In addition, an Accumulated Counter, the module provides a Rate Counter to
determine Rate Measurement by indicating the pulse input frequency in Hz. (See
the block diagram on page 6.) The Rate Measurement is determined by
accumulating input pulses over a fixed period of time. You set the Rate Period to
best match your application requirements.
Background Rate calculation is provided in Sequencer and Range Modes. This
operation accepts input rates up to 32,767 Hz. The dynamically configurable Rate
Period ranges from 10 ms to 2.55 seconds.
The module’s four current sink (open collector) outputs can be controlled in the
user program or the module.
Control of the counter reset is configured through user-set parameters. The counter
can be reset from any combination of the Z input, Limit Switch input, or Soft Reset
control bits.
Module operation is determined by selections made in the Setup and Control Word
(M0:e.1). Setting the Function Control bit to 1 triggers the module to start the
proper pulse counter, rate measurement, and output control functions. Many
parameters are dynamic and can be changed without disrupting counter operation.
The module’s block diagram is shown on page 6. Inputs from the terminal block
enter the diagram at the left, outputs to the terminal block exit at the right. M0 and
Output file parameters from the SLC enter the logic blocks from the top. Input file
data to the SLC exit the logic blocks from the bottom.

To Terminal Block
Two dip switches (SW1 and SW2) and one jumper (JW1) are located on the side of
the module.
• SW1 selects the type of input (single ended or differential).
• SW2 selects the output voltage range (4.5 to 10V dc or 10 to 30V dc).
• JW1 selects the filtering rate (300 µs or 10 ms) used to debounce the limit
switch input.
