Understanding the Allen-Bradley 1746-IV16
If you maintain Allen-Bradley systems, you know that not all replacement parts are created equal. The 1746-IV16 is a 16-point sourcing discrete input module engineered specifically for Allen-Bradley automation platforms. The aftermarket is flooded with modules that look identical on the outside but use inferior components internally. product type: Input Module; voltage category: 24V DC signal input (sourcing); number of inputs: 16; points per common: 16. We have tested clone modules side-by-side with genuine Allen-Bradley units — the clones typically fail within 3–6 months in continuous industrial service, sometimes taking out the backplane with them.
Every 1746-IV16 we sell is 100% genuine Allen-Bradley, with the manufacturer serial number and holographic label intact. We source from authorized distribution channels and decommissioned system tear-downs with full traceability documentation.
Before inserting this module, power down the chassis completely. Allen-Bradley modules are generally not hot-swappable. Verify backplane voltage with a calibrated multimeter before insertion. After installation, power up and verify the status LED shows normal operation before returning the system to service. Run the manufacturer diagnostic routine if available.
Compatible Parts — Same System
