Product Overview

The 1756-IB16K is an Allen-Bradley ControlLogix series DC digital input module offering 16 sinking inputs with conformal coating. It installs in a 1756 chassis and interfaces with backplane communications to relay discrete input status to a ControlLogix controller. Suitable for general-purpose sensing tasks in industrial automation, it supports environments exposed to contaminants or humidity.

Best Suited For

  • Discrete DC input sensing in ControlLogix systems
  • Environments requiring conformal coating protection
  • Integration with 1756 chassis backplane
  • Applications needing compact 16-point sinking inputs
