Integrated Relay Unit

Key Features :

• Monitors and commands subsystems through MIL-1553, AFDX, RS422, and Ethernet communication protocols.
• Develops and tests Seeker Relay Box.
• Integrates two relay sections—Power Relay Unit and Pyro Relay Unit.
• Interfaces each relay section with main and standby LIU.
• Qualifies design to MIL-STD-461E/F/G, MIL-STD-883, MIL-STD-344A & JSS-0256 standards.
• Uses ARTIX-7 (FPGA) for guidance through AFDX communication and Ethernet, RS422 & MIL-1553B protocols for alternate communication.
• Provides power through Power Relay Unit, fires pyro commands through Pyro Relay Unit, and interfaces with the launcher ground system through Seeker Relay Box.
