prodt-es-PER321APERFECTRON PER321A, powered by Intel® Atom™ Cedar trail D2550 dual core processor soldering onboard is a high-reliability Atom-based fanless rugged system that works perfectly under 80°C without processor throttling. Applied copper vacuum tube liquid-vapors (Heat-Pipe) and accompanied by the best ratio of heat dissipation volume in the industry, PER321A still operates smoothly with 1.86GHz clock rate speed under 80°C harsh environment, soundly interprets the advanced performance of Intel® Atom™ Cedar trail D2550 dual core processor. With its durability and anti-vibration resistance, it perfectly interprets a highly reliable solution for automatic optical inspection, industrial automation, access control, data acquisition, digital signage, and so on.


FANLESS operating at +80°C degree without processor throttling
PER321A is a model born for extreme temperature environments by proven outstanding operation performance under crucial conditions. Powered by Intel® Atom™ Dual Core D2550 1.86Ghz processor, it survives an extended market-leading operating temperature range of -40° to 80°C without processor throttling (reduced frequency) and continuously presents superior high performance.


Advanced Heat Pipe Thermal Solutionprodt-es-PER321A_Heatpipe2 (1)
PERFECTRON ensures that the computer systems we develop remain stable even in high temperature environments. Compared with the majority of companies using solid conductors such as aluminum, copper, graphite and diamond which have thermal conductivities ranging from 250 W/m•K to 1,500 W/m•K. PER321A applies copper vacuum tube liquid-vapors (Heat-Pipe) which have effective thermal conductivities that range from 5,000 W/m•K to 200,000 W/m•K to effectively transfer heat from the heat source (evaporator) to the heat sink (condenser). This advanced thermal solution enables PER321A to operate in a torrid environment without processor throttling.

Rich I/O and Expansion Features
The PER321A features an abundance of connectors through its I/O interface; it supports two COM ports for RS232/422/485 and another four for RS232, two RJ45 Ethernet LAN ports, four USB 2.0 on rear I/O and two by pin header, plus two mPCIe or one mSATA, all impressive capabilities provided for saving R&D resource during system integration or application implementation.



High Scalability and Flexibility
The PER321A is an industrial-grade system designed with high scalability and flexibility. In light of different necessity, COM ports can expand from six to ten that allow users to apply more specialized and custom-built devices. 16-bit DIO can meet the needs of wide range of industrial applications including the control of switches, relays, actuators, fans, lights, and motors that enable PER321A to achieve the best performance in industrial control and manufacturing test systems such as factory automation, embedded machine control, and production line verification.
