Product Short Description

Product Name: B&R X20CM0289 Counter Module

Product Overview: X20CM0289 is dedicated counter module for B&R X20 automation system, designed to process encoder signals and high-speed pulse measurement for motion feedback.

Technical Specifications:

  • Counter Channels: 2 independent counter channels

Description

  • Supported Signals: A/B incremental encoder, pulse/direction signals
  • Maximum Input Frequency: 4 MHz
  • Bus Connection: X2X Link

    Functional Features:

  • Quadrature signal decoding
  • Hardware position latch function
  • Zero marker signal processing
  • Software configurable counting modes

    Application Scenarios: Position measurement, speed feedback for servo axes, cutting length control, winding machinery.

    Performance Parameters:

  • Count range: 32-bit signed integer
  • Operating temperature: -20 °C ~ +65 °C

    Material Composition: Flame retardant plastic enclosure, high-speed signal processing PCB, spring terminal blocks.

    Structural Characteristics: Standard X20 modular form factor, DIN rail mounted, stacked with other X20 I/O modules.

    Working Principle: Hardware circuit captures encoder pulse signals, calculates position and rotation speed independently, transfers position data to CPU via backplane bus without occupying CPU computing resources.

    Installation Requirements: DIN rail installation; separate encoder cables from power cables to reduce interference.

    Usage Notes: Use shielded encoder cables; properly connect encoder power supply; avoid exceeding maximum input frequency specification.
