Specification

The 1756-IM16I Allen-Bradley ControlLogix Isolated 16-Point AC Input Module is a high-performance digital input solution engineered for demanding industrial applications where signal integrity and electrical isolation are paramount. This module features 16 individually isolated AC input channels, each capable of detecting AC signals from 85 to 265V AC at 50/60 Hz, making it ideal for monitoring limit switches, pushbuttons, and proximity sensors in power distribution, manufacturing, and process control environments. The galvanic isolation per channel eliminates ground loops and reduces electrical noise interference, ensuring accurate data acquisition even in electrically noisy plants. With its robust construction and LED indicators for channel status and fault detection, the 1756-IM16I simplifies troubleshooting and enhances system uptime. It integrates directly into any ControlLogix chassis (series A, B, or C) and is fully supported by Rockwell Automation's Studio 5000 environment for seamless configuration and diagnostics. Below is the detailed technical specification table for the 1756-IM16I.
