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.

Install the Module
Installation procedures for this module are the same as for any other discrete I/O or
specialty module.
IMPORTANT
ATTENTION
Set the dip switches before installing the module.
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. Align the full-size circuit board with the chassis card guide. The first slot of
the first chassis is reserved for the CPU.
2. Slide the module into the chassis until the top and bottom latches are
latched.
Make sure the removable terminal wiring block is attached to the module
and all wires are connected to the terminal block.
3. Insert the cable tie in the slots and secure the cable.
4. Cover all unused slots with the Card Slot Filler, Catalog Number 1746-N2.
Publication 1746-IN011C-EN-P - April 2005
Page 11
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
Remove the terminal block by turning the slotted terminal block release screws
counterclockwise. The screws are attached to the terminal block, so it will follow as
the screws are turned out.
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.
Wire the Removable Terminal Block
Use a flat or cross slot screwdriver to tighten terminal screws. Each screw should be
turned tight enough to immobilize the wire’s end. Overtightening can strip the
terminal screw. Do not exceed 0.7 to 0.9 Nm (6 to 8 in-lbs.).

12 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. We
recommend Belden 9503 or equivalent for lengths up to 305 m (1000 ft).
• When the LS input is driven by an electromechanical device, route the
wiring away from other inputs. In addition, JW1 should be set for the 10 ms
filter.
• When the LS input is driven by a solid-state device, use a shielded cable.
You do not have to route the cable away from other inputs.
• Shields should be grounded only at the end of the signal source end of the
cable. Ground the shield to the case of the signal source, so energy coupled
to the shield will not be delivered to signal source’s electronics.

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

14 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.
ATTENTION
Do not use incandescent lamps as output indicators. The high
peak inrush current required to heat the filament can damage
the module’s output circuits. Use LED indicators that satisfy the
output circuit ratings, such as Allen-Bradley 800A and 800T LED
indicators.
You can select an output voltage range of 4.5 to 10V dc or 10 to 30V dc. Refer to
page 21 for the maximum current specifications for each voltage range. Dip switch
SW2, located on the PC board, is used to select the voltage range. See pages 6 and
8 for switch SW2 location and settings.
The figure below indicates wiring connections for four 24V dc outputs. All switches
of SW2 are OFF for this output voltage.

Differential Encoder Output Waveforms
The illustration below shows the different encoder output waveforms. If your
encoder matches these waveforms, the encoder signals can be directly connected to
the associated screw terminals on the module. For example, the A lead from the
encoder is connected to the module’s A+ screw. If your encoder does not match
these waveforms, some wiring modifications may be necessary. Refer to the
