Allen-Bradley 1756-IB16 16-Point DC Input Module – ControlLogix

Allen-Bradley 1756-IB16 16-Point DC Input Module – ControlLogix Series

Imagine a high-speed automotive assembly line suddenly losing visibility into 16 critical sensor signals — conveyor positions, safety interlocks, and proximity switches all go dark simultaneously. Without a reliable digital input module, the entire PLC system is blind to the physical world, forcing an unplanned shutdown that costs thousands of dollars per minute. The Allen-Bradley 1756-IB16 is the precision interface that prevents exactly this scenario, converting real-world 10–31V DC field signals into the digital data your ControlLogix controller depends on for every scan cycle.

Within the ControlLogix 1756 platform — Rockwell Automation’s flagship modular control architecture — the 1756-IB16 occupies a foundational role as a 16-point sourcing DC input module. It is one of the most widely deployed digital input cards in the global industrial automation market, trusted across automotive, oil & gas, food & beverage, and discrete manufacturing sectors. Its combination of high channel density, broad voltage compatibility, and seamless integration with Studio 5000 Logix Designer makes it the default choice for engineers specifying ControlLogix I/O.

Our Quality Assurance Process

Every 1756-IB16 unit sourced and supplied by Konmask.com undergoes a structured verification process before shipment:

• Authenticity Verification: Visual inspection of Rockwell Automation labeling, date codes, and holographic seals to screen for counterfeit parts.
• Functional Testing: Where applicable, modules are bench-tested for backplane communication and per-point input response.
• Condition Grading: Units are clearly graded as New (factory-sealed), Refurbished (tested & reconditioned), or Used (tested, cosmetic wear). Grade is disclosed on every quotation.
• Secure Packaging: ESD-safe anti-static bags, foam cushioning, and double-wall cartons protect modules during international transit.
• Documentation: Test reports and certificates of conformance available upon request for critical applications.
