Description
Product Description
The 1756-IB32 is a high-density digital DC input module developed for the Allen-Bradley ControlLogix automation platform. Designed for industrial signal monitoring applications, this module provides 32 discrete DC inputs divided into two isolated groups of 16 channels for efficient field wiring and flexible system integration.
The Allen-Bradley 1756-IB32 accepts standard 10 to 31.2V DC input signals from industrial devices such as proximity sensors, pushbuttons, limit switches, and electronic field contacts. Its compact high-channel-density design helps reduce cabinet space while increasing input capacity within ControlLogix chassis systems.
Engineered for reliable operation in demanding industrial environments, the module delivers stable input detection, low backplane power consumption, and fast integration into distributed or centralized PLC architectures.
