CHATSWORTH, Calif. – Aitech Defense Systems Inc. in Chatsworth, Calif., is introducing the A174 I/O expansion subsystem to expand I/O capabilities of existing avionics systems with a standard Ethernet interface.
The small add-on unit offers small form factor and low power dissipation to expand the I/O of any avionics embedded computing system.
The A174 connects to a multiple-client/multiple-server system architecture with A174 servers and avionics computer clients on an Ethernet network. Each client can access and control I/O resources on any of the A174 units on the network, and any of the clients on the network can access each A174 simultaneously.
Each client can run processor architectures like PowerPC, ARM, Intel running any software operating system. The unit implements interfaces in a field-programmable gate array (FPGA), with only the physical layers acting as dedicated devices.
This minimizes power consumption, and enables customization of the unit to specific applications. The avionics expansion unit's Intel Cyclone V system-on-chip (SoC) FPGA implements all I/O interfaces, and the A174 also includes built-in test.
I/O interfaces include ARINC-429, analog and isolated discretes with optional RS-232/422/485 Serial and MIL-STD-1553B (BC/RT/MT) ports. System resources include temperature sensors and an elapsed time recorder as well as a pre-installed Linux Embedded operating system and drivers, server application, and test sample applications.
The A174 also offers EMI/RFI filtering of I/O signals, natural convection cooling, and a standard 28-volt power input of 16 to 32 volts DC with 50-millisecond power holdup time support, and environmental sealing. Power consumption typically is 13 Watts, with a maximum of 18 Watt, and operates in temperatures from -40 to 71 degrees Celsius.
