Product Overview

The 1756-IA32 is an Allen-Bradley ControlLogix digital AC input module providing 32 discrete input channels (organized as two groups of 16) for integration into ControlLogix PAC systems. Operating within the 74-132 VAC (47-63 Hz) range, this module monitors AC field devices and serves as an interface between sensors or signaling equipment and the ControlLogix backplane. It is employed in industrial control architectures where high-density AC discrete input monitoring is required, such as machine control panels, packaging lines, material handling systems, and plant automation applications.

Best Suited For

  • ControlLogix chassis with AC discrete inputs
  • High-density 120 VAC field signal acquisition
  • Distributed I/O schemes requiring group isolation
