Honeywell 51403393-100 Drive Tray Assembly for Industrial Control Racks

The 51403393-100 drive tray assembly provides a secure mounting platform for Honeywell storage drives in control cabinets. This steel carrier simplifies drive installation and replacement in process automation racks. Maintenance teams appreciate its tool-free handling and stable alignment during service work.

Physical Dimensions and Weight

The 51403393-100 measures 254 mm in width and 203 mm in depth. Its frame stands 25.4 mm tall, which keeps the tray profile compact inside dense racks. The assembly weighs approximately 1.6 kg, so one technician can carry several units comfortably.

Interface and Connectivity

This tray routes drive signals through a standard 50-pin SCSI connector at the rear edge. The 51403393-100 aligns the drive interface automatically during insertion. Consequently, mating completes without manual pin adjustment. Four guide rails ensure smooth engagement with the backplane connector every time.

Component Count and Build

Each 51403393-100 includes 2 side rails, 4 mounting screws, and 1 retaining bracket. The chassis uses 1.2 mm cold-rolled steel for structural rigidity. Furthermore, 6 rubber grommets dampen vibration between the drive and the tray frame.

Energy Storage and Power Parameters

The tray carries no active circuitry and stores no energy internally. Instead, the 51403393-100 passes 12 VDC and 5 VDC directly from the backplane. A 0.047 F decoupling capacitor sits on the connector board for signal smoothing. Therefore, the assembly adds negligible load to the host power budget.

Key Technical Parameters

Integration Notes

The 51403393-100 slides directly into standard Honeywell drive bays without adapters. Technicians secure the retaining bracket with one captive thumbscrew. Additionally, the guide rails prevent bent pins during hot-swap procedures in live cabinets.
