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
