Compact I/O High-speed Counter Module 5
Publication 1769-IN030B-EN-P - October 2010
Module Features
The 1769-HSC module is a 1 MHz counter/encoder input module with 4 onboard
5…30V DC sourcing outputs designed for high-speed control applications, such as flow control,
measuring length, position, speed, frequency, or duration. The module can simultaneously
interface with a maximum of two quadrature incremental encoders or four single-input count
inputs from devices, such as proximity sensors, photo-eyes, single-pulse output encoders (with or
without direction), or similar products used to monitor counting, flow, or frequency.
The input voltage range is 2.6…30V DC. The 1769-HSC module includes all of the standard
1769 I/O module features, such as rackless, removable terminal block, integrated high-speed
bus/backplane, panel, or DIN rail mounting.
These are additional features:
• Two quadrature (ABZ) differential inputs alternately configurable for the following:
– Pulse internal direction input (four counters in this configuration)
– Pulse external direction input
– Up and down pulse input
– X1, X2, or X4 quadrature encoder input
• 32-bit count values (±2 billion counts)
• 21-bit rate values (±1 MHz)
• User-definable minimum and maximum count values
• Individual counter reset function (0 = reset enable (default); 1 = reset disable)
1769-HSC series B module only
• 16 user-defined ranges with each range individually assignable to 1 of the 4
counter channels
• User-definable preset
• Linear or ring counter operation
• Selectable input filters
• 5…30V DC counter/encoder inputs and control outputs
• 4 real (physical) outputs and 12 virtual (control bit) outputs
• Real outputs have electric overcurrent protection and rated current of 0.5 A per channel
• Safe State control options (options depend on which controller is used) to allow the
module to operate during fault or program conditions
