Description

Designed for high-precision pulse tracking and motion sensing, the CS1W-CT021 serves as a dedicated high-speed counter module within the Omron SYSMAC CS1-series PLC platform. This module enables real-time processing of high-frequency input signals from rotary encoders, linear scales, and proximity sensors, bypassing standard PLC scan cycle limitations to ensure microsecond-level response accuracy.

The unit interfaces directly with the CS1 backplane, drawing power efficiently while communicating high-speed count values, status flags, and control parameters directly to the CPU. It is built to operate reliably in demanding industrial automation environments, supporting complex positioning, speed measurement, and synchronization tasks across various manufacturing systems.

Features

  • Direct integration with Omron SYSMAC CS1-series PLC backplanes.
  • Optimized internal power consumption of 360 mA at 5 VDC.
  • Maintains tracking accuracy across standard industrial ambient temperatures.
  • Robust environmental resistance with 10% to 90% non-condensing relative humidity tolerance.

Applications

  • Precision positioning systems in packaging machinery.
  • Rotary encoder speed tracking and feedback loops.
  • Cut-to-length application controls.
  • Conveyor synchronization and sorting systems.

Installation Guidelines

When installing the CS1W-CT021 high-speed counter unit, adhere to the following engineering practices:

  • Ensure the PLC rack power is completely turned off before mounting or removing the module from the CS1 backplane.
  • Use shielded, twisted-pair cabling for all high-speed counter input signals to minimize electromagnetic interference (EMI) from adjacent power lines.
  • Ground the shield at the PLC side to a dedicated functional ground terminal (100 ohms or less) to maintain signal integrity.
  • Verify that the ambient operating temperature inside the control panel does not exceed 55 degC, ensuring adequate spacing and airflow around the rack.
