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.

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.
