Honeywell 51303968-100 — Functionally Tested Before It Leaves Our Warehouse
The Honeywell 51303968-100 CMOS Backup Assembly Board is a cmos backup assembly board that serves a specific function within the Honeywell automation architecture. In the industrial surplus market, the word "tested" is used loosely. We define it precisely: visual inspection for physical damage, power-up on a live Honeywell rack with correct backplane voltage, all channels exercised with calibrated signal sources where applicable, communication ports verified, and 48 hours of continuous operation at 55°C ambient to catch early-life failures.
Model Number:: 51303968-100; Type:: CMOS Backup Assembly Board; Voltage:: 3.6 V; Capacity:: 2500 mAh. These are actual measured specifications from our latest stocked batch — not copied from a datasheet, not assumed from the part number. When you receive this module, you receive a unit that has been through a real test process, not a checkbox exercise. A printed test report with serial number, test date, and all measured values accompanies every shipment.
Industrial automation modules are designed for 10-20 year service lives, but all electronics eventually fail. The question is whether you have a tested replacement on hand when that happens. For critical applications where downtime is measured in thousands of dollars per hour, the cost of one spare module is negligible compared to the cost of one unplanned outage. Genuine Honeywell with full traceability. 12-month warranty. Ships within 24 hours from Shenzhen via DHL, FedEx, or UPS.
