Acromag - Fanless Industrial PC with Modular I/O Receives UL Approval for Use in Hazardous Locations  


Acromag's rugged I/O Server Industrial PC is now UL/cUL listed with approval for use in Class I Division 2 Groups A, B, C, D hazardous environments containing volatile substances.

Already ruggedized for dependable computing in sites subject to extreme temperatures, shock, and vibration; thAcromagfanless2e Acromag I/O Server Industrial PC now has Underwriters Laboratory (UL) certification for Class I Division 2 Group A, B, C, D hazardous locations with volatile substances. This UL approval permits use of the I/O server fanless embedded computer and its plug-in I/O modules in environments with flammable liquids, gases, or vapors. UL's Class I Div 2 certification is often required for electronics deployed in chemical, oil, gas, mining, and other manufacturing facilities. With the higher safety rating, the I/O Server can be installed closer to sensors and actuators to reduce installation costs for monitoring and control of automated machinery. Additionally, the I/O Server has no internal cables and conduction cooling removes heat without open vents or fans for more reliable operation from -40 to 75°C.

Symmetricom- Mitigating GPS Interference  

GPS receivers have been widely used in communications infrastructure to provide precise time and frequency required to synchronize wireless base stationSymmetricom logos to ensure seamless call handoff, quality streaming video and location based services such as car navigation systems and most notably E911 services in the US. However, recent events have shown that GPS is susceptible to interference from deliberate spoofing and jamming techniques which can seriously disrupt or even completely disable GPS dependent applications and natural outages as with urban canyons.
