The OXY5737A offers highly effectively heat conductive and heat convective thermal solutions to meet the demands of customers’ extended temperature requirements. The heat conductive solutions uses an aluminum flat mass to place in direct contact with the processor and chipset, the heat from chips then transfers it to the case of the system. In addition, the convective thermal solutions introduce airflow directed to move across the surface of a fin style heatsink placed on top of the processor and chipset. This can be done with the aid of an appropriately sized fan placed in top of the fin style heatsink. Alternately, enclosure airflow can be routed to flow across a fin style heatsink.

The SR100 can operate effectively in harsh environment under temp range from -40 to 70°C. SR100 is based on EBX form factor which features with stackable PCIe/104 and FPE expansions, on board Nano SATA(3.0)16/32 Giga Byte SSD and XR-DIMM up to 8GB. It supports triple-display like 2 DP and 1 DVI-I, 2 GIGA LAN port, 4 USB (2 x 2.0, 2 x 3.0), 1 COM port and 2 mPCIe Expansion slots (one co-layout with mSATA). SR100 supplies wide power voltage from 9 to 36V DC-in. 

SR100 main board: EBX SBC-OXY5737A

(1) Intel ® Core i7 CPU soldering onboard


SR100 is based on EBX SBC—OXY5737A, powered by Intel® i7-4700EQ quad core processor plus QM87 chipset soldered onboard. With CPU soldering onboard, there is less conduction of heat and high density interconnection between the motherboard and the components, which reduces the MB from the crisis of overheating. Apart from overheating, soldering onboard also provides the best level of shock and vibration protection, removing the unnecessary concern about poor connection that CPU socket type may bring.


(2) Stackable with PCIe/104 & FPE expansion

Known for application ruggedness, reliability, sealing properties, and compactness characteristics, PCIe/104 & FPE connectors are ideal for high-end electronic equipment and use in extreme environment conditions. With easy connect/disconnect and blind mating, SR100 has a functional life greater than 10,000 mating cycles. The PCIe/104 connector on SR100 that specifies standard of SAMTEC Q2™ QMS/QFS series in a three bank (156-pin) orientation for module stacking. SAMTEC designed the QMS/QFS series with a 15.24 mm stack height for top and bottom board stacking. And the Q2™ has triple the wipe of many high speed mezzanine interconnects making SR100 the best choice for tough environmental conditions.



(3) Wide Range DC input


For train recording usage, device interfaces are mostly go from LAN ports and COM ports. To add two more Ethernet ports, RC200 adds on LAN card by mPCIe interface, which is developed by PERFECTRON—MT321. Sufficient 10/100/1000 mbps Ethernet connections enable to install more complete surveillance system in vehicle as well as build up interconnection to manage carriage-to-carriage communications, which effectively increase efficiency and safety. It is noteworthy that two out of four connections apply locking M12 connectors to minimize the chance of disconnection caused by shock & vibration during the railway journey. For more I/O support, RC200 provides total 4 COM ports, optional 2 COM ports with isolation. With isolation function, it can provide secured power protection from sudden power surge damaging the controller.


(4) Elaborate thermal design

For intellectual video wall and defense control room applications, the system is always working 24/7 nonstop operation which makes the system always keeps at high temperatures. Therefore the importance of extended operating temperature is undoubted. PERFECTRON experts develop a brand new thermal design which involves segmentation type thermal design, integrating solidly with heat pipe, heat spreader and heat sink which allows SR100 to survive from -40 to +75°C. The thermal solution flexibly maximize the metal characteristic, using copper heat spreader to absorb heat directly from heat sources, then using heat pipe to transfer heat to aluminum heat sink. The copper heat pipe is the key factor among the whole thermal design. The heat conductivity coefficient of heat pipe can be up to 5000, nearly 12 times better than copper heat spreader. With a perfect combination of copper plus aluminum thermal kit which efficiently manage the heat dissipation up to 75°C.
