CompactPCI I/O Cards are radiation tolerant.
Press Release Summary:
Analog Model S930 and digital Model S940 FPGA-based cards enhance real-time communication and I/O functions between control subsystems and external subsystems. Both feature triple redundant buffer memory and can generate interrupts, eliminating need for onboard processor to manage I/O. Onboard BIT circuitry and logic enable self-monitoring. Conduction-cooled cards come with component screening to NASA GSFC 311-INST-001A Level 2, making them suited for high density aerospace applications.
Original Press Release:
New Rad-Tolerant 3U, CompactPCI I/O Cards from Aitech Enhance Real-Time Communication Functions in Control Subsystems
Chatsworth, CA, April 2007 - Aitech Defense Systems, Inc., the world's first and largest independent manufacturer of open architecture board and subsystem level products for harsh environment defense, aerospace and astronautics applications, now offers two radiation-tolerant 3U, CompactPCI (cPCI) I/O cards that increase real-time communication and I/O functions between control subsystems and external subsystems. The cost-effective analog S930 and digital S940 FPGA-based cards both feature triple redundant buffer memory and can generate interrupts, eliminating the need for a more costly onboard processor to manage the I/O.
The conduction-cooled cards come standard with component screening to NASA GSFC 311-INST-001A Level 2, making them ideal for high density, rugged, aerospace applications such as satellites, other spacecraft and the International Space Station, where they are currently in use today.
These new, low-power single-slot I/O cards incorporate a PCI bridge implemented by an anti-fuse FPGA for added radiation tolerance that allows a processor module to access the I/O from the cPCI bus. Their onboard BIT (burn-in test) circuitry and logic enables self-monitoring.
Each card also offers specific advantages. The S930 employs a 12-bit A/D converter that enhances subsystem sensitivity by detecting minute changes in externally-sensed voltages. It also features 64 analog channels (51 inputs, two outputs and 11 bus voltage monitors) as well as a low pass filter with cutoff frequency below 50 Hz on all inputs. The board draws less than 10 W of power.
The S940 incorporates an H-bridge that efficiently provides pulse code modulation (PCM) control and drives the DC motors, and its four RS422 inputs and 12 RS422 outputs help DC motor controls sense how the motor is operating. Additional interfaces include a reaction wheel tachometer interface, a separation switch closure interface and a torque rod interface. Power consumption is less than 13.5 W.
Aitech employs stringent quality control and product testing practices for the S930 and S940 that help lower product development risks, reduce time to market and decrease fielding and maintenance costs for users. The company is certified to ISO9001:2000 and AS9100:2001 as well as registered and certified by NASA for ANSI/J-STD-001 assembly and IPC-A-610B inspection processes.
Both the S930 and S940 are available in air- or conduction-cooled versions and various component quality standards from ceramic to fully NASA-level certified.
Pricing for the S930 is $10,000 and for the S940 is $13,170 in OEM quantities. Delivery is from stock for software development models.
