Product Overview

The 1794-IA8 is an Allen-Bradley Flex I/O digital input module designed for 120 V AC field inputs. With eight non-isolated sinking inputs, it integrates into the 1794 Flex I/O system, providing distributed digital input capability for control systems. In a typical installation, the 1794-IA8 mounts on a terminal base alongside an adapter module and communicates over FlexBus, enabling detection of machine states, limit switches, or proximity sensors in process or discrete automation applications.

Best Suited For

  • Distributed 120 V AC sensing in Flex I/O systems
  • Monitoring proximity or push-button inputs in machine controls
  • Applications using standard 120 V AC control power
  • Quick replacement in modular I/O racks
