New Benchmark for Industrial Ethernet Reliability
Many mission-critical applications in industrial automation require highly-available network transmissions to provide real-time monitoring and control, prevent production losses from system downtime, and ensure onsite personnel safety.
CHESHUNT, U.K. - Oct. 8, 2013 - PRLog -- New Benchmark for Industrial Ethernet Reliability
Many mission-critical applications in industrial automation require highly-available network transmissions to provide real-time monitoring and control, prevent production losses from system downtime, and ensure onsite personnel safety. However, many factors commonly found in industrial environments, such as electro-magnetic interference and noise, severe shock and vibration, and high temperature variations can quickly compromise system reliability. For example, in high-voltage power distribution networks, severe electromagnetic interference can disable network switches and interrupt data communication. In railway trackside networks, switches inside outdoor cabinets face challenging environmental conditions, which can include serious vibration, electrical surge, and high temperatures. Therefore, industrial Ethernet switch robustness is a critical factor to achieve highly reliable networks.
IEEE 1613 compliance provides Level 4 EMS protection and is needed to resist electro-magnetic interference in power substations. However, high levels of noise interference are not only found in power distribution networks, but can also exist in railway wayside networks and even on factory floors. IEEE 1613-compliant switches are not just suitable for power substation applications, they can offer any industrial network a higher level of reliability and lower total cost of ownership.

To address reliability concerns, Moxa’s next generation EDS E series industrial Ethernet switches are engineered to offer a higher level of protection than typical industrial switches to provide seamless data transmission of mission-critical applications in various harsh environments. To deliver ultra-robust performance, the EDS E series switches not only meet Level 4 EMS standards with laboratory-proven immunity to electromagnetic interference, they are also compliant with railway standards for vibration and are resistant to highly unstable industrial environments. Furthermore, the aluminum thermal fin panels are meticulously designed using simulation tests to optimize air flow and heat dissipation, which can significantly reduce internal component temperatures to enhance system reliability.

EMS Level 4 Protection
Electromagnetic Susceptibility (EMS) is the inability of an electronic device to operate unaffected in the presence of interfering electromagnetic energy. The new EDS switch is compliant with Level 4 EMS standards and has passed ESD, EFT, and surge tests to provide better protection when electromagnetic interference occurs.

Electrostatic Discharge Immunity
Electrostatic discharge is the sudden transfer of static electricity between two objects and can cause equipment failure and network disruption. The new EDS switch is able to maintain normal operation even at ±8 kV contact discharges or ±15 kV air discharges. With Level 4 ESD protection, the new EDS switch was unaffected by the repetitive contact discharges.
EFT/Surge Immunity
Bursts of electrical fast transients are caused by operation of motors and electro-mechanical switches, which can damage internal circuitry. Voltage surge may destroy electronic hardware through a lightning strike or power outage recovery. We applied EN 61000-4-4 and IEC 61000-4-5 standards to conduct both EFT and surge tests separately. With Level 4 EFT protection, EFT/surge injections did not affect the performance of the switch and can keep substation applications running uninterrupted
Anti Vibration and Shock Resistant Test
Long-term exposure to shock and vibration can eventually disable a device by shaking loose wires for power, data, and redundancy. The new EDS switch was subjected to 5 ~ 150 Hz random vibrations. The half-sine duration was 30 minutes and peak acceleration was X/Y/Z Axis at 5 g (50 m/s²) for the shock test. With the newly designed DIN rail kit, the EDS E series switch successfully resists high levels of shock and vibration, and allows easy switch installation.
Optimized Thermal Design Simulation
Heat is another factor affecting device reliability. In the numerical simulation of thermal dissipation, the new EDS switch expels heat across both side panels of thermal convection fins. In a burn-in room with 75° C ambient temperature, hot spots on both the switch surface and inside the switch were much lower when the switch was equipped with the outer thermal panels than when it was open to the air without the panels.
