SPERRY MARINE T65801813-8 INPUT PCB ALOFT CARD REV.B

This board is part of the radar scanner/turning unit electronics — the core part of the radar that rotates the antenna and processes incoming/outgoing signals.
It receives electrical input signals from the Power Supply Unit and sends them to the Scanner Control Unit to help initiate and control antenna rotation of the radar.
In other words, it’s responsible for handling and processing key internal signals that support reliable operation of the radar’s rotating and signal chain systems.

Technical Specification

Manufacturer / Brand: Sperry Marine (Northrop Grumman Sperry Marine)
Part Number: T65801813-8
Name: Input PCB Assembly, Aloft Card (for marine radar turning/scanner unit)
Revision: Rev.B (earlier version than the more common Rev.C)
Application: X-band (10 kW) or similar marine radar scanner electronics used in Sperry Marine systems such as VisionMaster series.
Electrical
- Power Interface: Likely powered by low-voltage DC derived from the radar turning unit’s internal supply (typ. 24 VDC or regulated internal rails)
- Signal Interfaces: Multiple logic and analog signal connections between other scanner PCBs and control modules
Physical / Mechanical
- Form Factor: PCB assembly designed to mount inside radar scanning unit enclosure
- Connectors: Edge-card or harness-type connectors for internal subsystems
- Components: Discrete components, ICs, and possibly analog/digital interfaces
Environmental
- Designed for marine environment conditions (temperature, vibration/shock), consistent with maritime radar equipment standards (IEC 60945 style environmental standards in similar radar turning units)
