Information About 7510100-731
The 7510100-731 Integrated Navigation Unit consists of multiple modules housed in a single chassis, including the NV-850 NAV Receiver, DM-850 DME Interrogator, DF-850 ADF Receiver, and XN-850 NAV Cluster Module. Each module connects through ribbon cabling and interfaces via the Radio System Bus (RSB) and RS-422 digital outputs. Operating on 28 VDC with additional 26 V, 400 Hz inputs depending on synchro load, the unit meets multiple TSO standards and DO-160B environmental requirements. It is designed for aircraft installation up to 70,000 feet with wide temperature tolerance from -55°C to +70°C.
