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
