1746-IB32 Allen-Bradley SLC 500 32-Channel DC Input Module for Industrial Automation

The 1746-IB32 is a high-performance 32-channel DC input module from Allen-Bradley, designed for the SLC 500 modular industrial control system. Engineered for reliable industrial automation applications, it supports 10-30 VDC sinking/source input signals and features 8 grouped 4-channel configurations for flexible wiring and signal management. With robust channel-to-logic and channel-to-channel electrical isolation, the module protects the SLC 500 controller from voltage surges and electrical interference, ensuring stable operation in harsh factory floor environments. Equipped with per-channel LED indicators and a module power LED, it enables quick visual diagnostics of input status and module health, reducing troubleshooting time. The compact 1.5-inch form factor optimizes chassis space utilization, making it an ideal choice for discrete manufacturing, process control, and machine automation systems that require high-density DC input signal acquisition. Fully compatible with all SLC 500 chassis models, the 1746-IB32 delivers seamless integration and consistent performance, meeting the rigorous standards of industrial automation with UL, cUL, and CE certifications.
