Allen-Bradley 1756-IB32 Discrete Input Module

The Allen-Bradley 1756-IB32 is a ControlLogix I/O module that provides 32 discrete DC input points for monitoring field signals in 12/24 V DC systems, enabling scalable input expansion for automation architectures. Each channel features optical isolation and supports either sinking or sourcing configuration, with mounting options on DIN rail or chassis mount depending on the system, and it communicates with Controllers via the ControlLogix backplane interface. This module is designed to integrate with Allen-Bradley ControlLogix controllers, making it suitable for distributed control networks in manufacturing environments such as conveyors, packaging lines, material handling, batch processing, and complex control panels that monitor sensors, switches, and proximity detectors. Operating temperature ranges from 0°C to 55°C, and it is compatible with the ControlLogix I/O series, with common replacements including the 1756-IB16 and 1756-IA32.
