Safe Computer Solutions Failures of safety-critical electronic systems can result in loss of life, substantial fi nancial damage or can severely harm the environment. A safe computer allows direct control of safety-critical functions, meaning that the computer tolerates hardware faults and guarantees an undetected erroneous behavior of <1E-9/h. MEN provides safety at system level and even at board level. Safety is mainly achieved by built-in redundancy for critical function blocks like CPU, memory and internal FPGA structure. With triple redundancy the system remains functional even if one CPU or memory bank delivers a different result, thus providing reliability in addition to safety. Conductive Cooling Solutions The appropriate cooling method is essential for every application. Unlike forced air cooling, conduction cooling optimizes the thermal contact to conduct the heat from the source to the outer wall of the enclosure. This makes the enclosure itself a heat radiator. Suitable measures must be taken to minimize the thermal transfer resistance from the electronic component to be cooled to the enclosure wall. On the one hand, this is ensured by choosing the right materials. On the other hand, the boards inside the enclosure need to be placed in the right way, and the heat-conducting cooling blocks need to have such masses that optimum heat transport is guaranteed.

D602 – Triple-Redundant 6U CompactPCI® PowerPC® SBC ¡ Triple redundancy on a single SBC ¡ Lock-step architecture ¡ Safe computer, certifi able up to DAL-A and SIL4 ¡ With safety operating systems PikeOS and VxWorks® Developed originally as a safe computer for controlling the freight load system of the Airbus A400M, the computer assembly D602 is now also available as COTS hardware for CompactPCI® systems. It is used in safety-critical applications in airplanes (up to DAL-A) and in trains (up to SIL 4). D602 provides complete triple redundancy of the hardware components on a single board for the...

The F50C is based on Freescale’s MPC8548 with clock frequencies between 800 MHz and 1.5 GHz. The 3U CompactPCI® single-board computer supports rear I/O and by default comes with a specially designed CCA frame for conductive cooling. This frame gives the card 5 HP in size and allows the SBC to be used in MEN’s conductive cooling housing in a temperature range of -40 °C to +85 °C. With front I/O and a heat sink for convection cooling the F50P sister board is also available for application in common 19” systems. The F50C has 2 GB ECC DDR2 SDRAM main memory, a 16 GB solid state Flash disk (SSD) for...

This rack allows to use 3U CompactPCI® boards – which by standard were designed for an operating temperature of -40 to +85°C with convection cooling – in a conductioncooled environment. For this purpose MEN develops a special CCA frame for its CompactPCI® single Eurocards which is specially adapted to the board in order to ensure appropriate cooling. The fi rst single-board computer MEN has adapted in this way is the F50C which is based on Freescale‘s MPC8548. The power-saving F14 to F19P boards (from Celeron® M up to Core 2 Duo) of the 3U CompactPCI® Intel® family are also suited for these frames....
