1794-IM16

Product Overview

1794-IM16 is an Allen-Bradley FLEX I/O 16-point digital input module from Rockwell Automation designed for distributed industrial automation systems. This module provides 16 non-isolated 240V AC digital input channels for FLEX I/O platforms, allowing field devices such as switches, sensors and control signals to be connected directly to remote I/O systems. With DIN rail mounting, LED status indicators and compatibility with FLEX I/O communication adapters, it is widely used in factory automation, machine control, process monitoring and legacy Allen-Bradley PLC applications.
