Allen-Bradley 1756-CFM

Overview

The Allen-Bradley 1756-CFM is a 2-channel frequency module for the ControlLogix platform, capable of both input and output frequency signal processing. It supports signal ranges of 5–24V DC and provides channel-to-channel isolation, making it ideal for high-speed counting, RPM measurement, and frequency-based control systems.

Key Features

  • Channels: 2 (independently configurable as input or output)

  • Voltage Range: 5–24V DC

  • Mounting: DIN rail via ControlLogix chassis

  • Isolation: Channel-to-channel and from backplane

  • High-Speed Capability: Suitable for fast pulse signals

  • Configuration: Via Studio 5000 or RSLogix 5000

Technical Specifications

  • Catalog Number: 1756-CFM

  • Input Frequency Range: 0 Hz to 25 kHz

  • Output Frequency Range: 0 Hz to 20 kHz

  • Input Impedance: 10 kΩ (nominal)

  • Output Drive Capability: 100 mA max per channel

  • Isolation Voltage: 250V (continuous)

  • Backplane Current Load: 350 mA @ 5.1V DC, 0 mA @ 24V DC

  • Operating Temperature: 0°C to +60°C

  • Storage Temperature: -40°C to +85°C

  • Certifications: UL, CE, CSA, RoHS

Applications

  • Rotational speed/RPM monitoring

  • Flow measurement systems

  • Pulse signal counting

  • Frequency-based control loops

  • Conveyor and motor control systems

Why Choose the 1756-CFM

  • Flexible I/O Design: Use channels independently as input or output

  • High-Speed Compatibility: Ideal for time-critical applications

  • Robust Isolation: Enhanced electrical protection

  • Integration Ready: Seamless with ControlLogix systems

  • Reliable Performance: Built for continuous industrial use
