Description

The Allen-Bradley 1756-IB16ISOE is a specialized 16-point DC digital input module designed for the ControlLogix platform. Engineered for high-precision timing, this module supports Sequence of Events (SOE) recording, enabling users to capture and timestamp critical system events with high resolution. It features individually isolated inputs, providing enhanced noise immunity and flexibility in complex industrial control environments.

Features

  • 16 individually isolated DC input channels.
  • Integrated Sequence of Events (SOE) recording functionality.
  • Wide operating voltage range of 10-55 VDC.
  • Front-panel status indicators for input state, communication health, and module diagnostics.
  • Supports both sink and source wiring configurations.
  • Optimized for high-speed event capture with configurable input filtering.

Applications

This module is ideal for applications requiring precise event logging, such as power distribution monitoring, safety-critical interlocking, and diagnostic analysis of industrial processes where the exact order of operations must be maintained for troubleshooting or regulatory compliance.
