The redundant power inputs on Moxa’s industrial Ethernet switches can
be a life saver; if oo hne power source fails, the redundant power input
will kick in and keep the entire system operating safely. Some models
feature a wide range of 12/24/48 VDC power inputs, and can handle
large power fluctuations (e.g., 48 VDC can handle voltage increases of
up to +20%, and 12 VDC can handle voltage decreases down to -20%).
If your application is restricted to VAC input power, choose a Moxa
Ethernet switch (such as the EDS-200A/200 series) that is specially
designed tandle AC power. With these switches you can use either a
24 VDC or 24 VAC power input. |

Industrial environments can be excruciatingly hot or unbearably cold, and require network devices to operate under wide temperature conditions. Moxa’s Ethernet switches are subjected to rigorous testing beyond industry strandards to ensure their fortitude in a -40 to 75ºC operating temperature range. For instance, while regulatory standards |
|
 |
| |
require only a temperature change of 1 ºC /minute throughout the cycling examination, Moxa has conducts stricter testing using 3 ºC/minute. Intolerable packet-loss requirements are also defined to ensure that Moxa’s Ethernet
switches function robustly. In addition, Moxa’s switches also feature passive cooling schemes, so that reliability can be further assured under excessive heat. |

Outstanding Electromagnetic Immunity |
|
 |
|
|
The rugged design of Moxa’s industrial Ethernet switches includes
excellent electromagnetic immunity that often surpass the requirements
stipulated by EN50121-4, DNV, and IEC 61000. For example, to provide immunity against magnetic fields induced by power frequencies, Moxa
designs for 300 A/m applied continuously and 1000 A/m applied for 1 to
3 second intervals, which is three times stricter than EN50121-4. |

Network Connections Well-protected against Harsh Environmental Conditions |
|
 |
|
|
|
|
| Moxa’s Ethernet switches are built to endure harsh environmental
conditions. For example, vibration is a significant challenge for maritime
and transportation applications. Moxa’s switches conform to the
IEC60068-2-6 standard and are tested at over 1 g of acceleration for
an extended time period. When it comes to shock impacts, some of
Moxa’s Ethernet switches are designed to exceed other standards, such
as NEMA TS2, by an |
 |
| additional 5 g’s of acceleration.Moreover, all Moxa
products feature a rugged and high strength housing to protect against
the dust and spills that are commonplace at manufacturing locations. |

Networking Solutions Certified to Meet Industrial Standards |
|
|
|
| |
|
Several standard certifications confirm the reliability of Moxa’s industrial Ethernet switches, such as: |
|
|
|
 |
UL508 and UL60950-1 certifications for safe use in hazardous locations |
|
|
|
DVN/GL/ABS/LR/NK for maritime environments |
|
|
|
Class I, Division 2/ATEX Zone 2 for use in the mining, oil and gas industries |
|
|
|
NEMA TS2 for traffic control applications |
|
|
|
EN50121-4 for railway wayside applications |

Relay Output Alarm, Broadcast Storm Protection, 5-year Warranty |
|
|
| |
|
|
|
|
Many of Moxa’s Ethernet switches feature relay output alarms. It
provides relay contact outputs to warn engineers on the shop floor
when power fails or a port link breaks, so that they can respond
quickly with appropriate emergency procedures. |
|
|
|
Moxa’s unmanaged Ethernet switches are protected from receiving
too many broadcast packets. These Ethernet switches have an
option to discard broadcast or multicast packets if the number of those packets exceeds a threshold in a present period of time. When
the preset time period expires, the switch will then resume receiving
broadcast or multicast packets until the threshold is reached again. |
|
|
|
All of Moxa’s Ethernet switches are fanless in design with high MTBF
(Mean Time Before Failure) ratings for long-term operations. In
addition, Moxa’s guarantees the products with a solid 5-year
warranty. |
