Product Overview

The 1756-IN16 is an Allen-Bradley ControlLogix digital AC input module that provides 16 discrete input points (organized in two groups of 8) for processing 10 … 30 V AC signals. It installs in a 1756-series ControlLogix chassis and connects via a removable terminal block. The module isolates inputs by groups and supports configurable filtering and diagnostics. It is typically used in industrial control systems for status monitoring and discrete signal acquisition in machinery, conveyors, packaging, or process control systems. Part number 1756-IN16.
