Genuine Allen-Bradley 1756-IB16D Digital Input Module | ControlLogix – Verified Source
The Allen-Bradley 1756-IB16D is a 16-point, 10–30V DC sourcing digital input module within Rockwell Automation’s ControlLogix platform — one of the most widely deployed programmable automation controllers in heavy industry, oil & gas, automotive, and critical infrastructure worldwide. Its diagnostic-grade design (the “D” suffix denotes full diagnostics) makes it irreplaceable in safety-sensitive and high-availability applications. Due to its long production lifecycle and global demand, the 1756-IB16D is a frequent target for counterfeit reproduction, grey-market diversion, and refurbished units misrepresented as new — risks that can result in unplanned downtime, failed audits, or safety incidents.
At Konmask, every 1756-IB16D unit is sourced exclusively through verified industrial distribution channels and undergoes a documented 4-step quality verification process before dispatch. We supply only genuine, authentic, original Allen-Bradley modules — never refurbished, relabelled, or third-party clones. Our verified sourcing process, combined with full traceability documentation, gives procurement engineers and plant managers the confidence to specify Konmask as a trusted supply partner for genuine Rockwell Automation components.

Our 4-Step Quality Verification Process
- Step 1 — Source Authentication: All units are procured from traceable industrial distribution channels. Supplier credentials, purchase invoices, and chain-of-custody records are retained for every batch. We do not source from open marketplaces or unverified brokers.
- Step 2 — Physical Inspection & Label Verification: Each module is inspected against Rockwell Automation’s published physical standards — holographic labels, date codes, PCB markings, and housing tolerances are cross-checked. Any unit with anomalies is quarantined and rejected.
- Step 3 — Functional Bench Testing: Modules are powered up and tested for correct backplane communication, input point response, and diagnostic signal integrity using ControlLogix test chassis. Test results are logged per serial number.
- Step 4 — Documentation Package: Every shipment is accompanied by a full documentation set upon request: Certificate of Conformance (COC), Functional Test Report, Packing List with serial numbers, Country of Origin (COO) Declaration, and high-resolution photos of the actual unit shipped.
Key Features & Benefits
- Full Diagnostic Capability: Open-wire, short-circuit, and field-power-loss detection per IEC 61131-2 input module diagnostic standards — enabling predictive maintenance and reducing unplanned downtime.
- Software-Configurable Input Filtering: 0–2 ms adjustable input delay allows optimisation for both high-speed sensing and noise-immune applications without hardware changes.
