Proven Marine-grade Industrial Ethernet Switches
An Ethernet-based network enables multimedia capability such as video, voice, and data transmissions to be efficiently consolidated with daily onshore and offshore activities into a centralized system, and improves the safety and well being of both the crew and ship. With certification from all the major maritime classification societies, Moxa industrial Ethernet switches ensure superior and stable Ethernet connectivity for marine applications such as ship engine systems, monitoring systems, and offshore wind power systems, despite extreme maritime environmental factors. For reliable performance, network redundancy, electromagnetic compatibility, and Gigabit bandwidth, Moxa switches are the ideal choice.
 

Some of Moxa's industrial Ethernet switches and video servers are marine-grade and have passed various marine environmental tests:

Norway DNV (Det Norske Veritas) Certification No. 2.4, April 2006
Germany GL (Germanischer Lloyd) Certificate No. 8610409 HH
London LR (Lloyd's Register of Shipping) Certification No. 10/00005, 2002
USA ABS (American Bureau of Shipping) Certification No. 09-LD485789A-PDAs
Japan NKK (Nippon Kaiji Kyokai) Certification No. TA09372M

These strict tests ensure optimal device performance in harsh environments, including continuous exposure to dry heat, cold/hot temperatures, humidity, high voltage, vibration, power surges, and shock. These rigorous safety standards ensure long-lasting, reliable operation in ship, offshore oil/gas, and windmill environments. In addition, Moxa's industrial Ethernet-to-fiber media converters, serial device servers, and embedded computers have all passed rigorous DNV testing, making them perfectly suited for hazardous ship environments.

Offshore wind power applications are similar to typical onshore wind turbine projects. Both types require careful planning during the construction phase, and it is best to manage wind turbine systems remotely from a central control center. In order to keep the installation cost at a reasonable level, most wind turbine sites are made up of many turbines. In fact, the turbines are often erected in rows, in the same way that crops are planted.

Moxa's EDS family of Industrial Ethernet Switches and IMC family of Industrial Media Converters have received DNV Certification, and all tests meet or exceed the requirements of the guidelines laid out in ICAS Unified Requirement E10.
 

Wireless technology has been used for commercial applications for a number of years. WiFi/IEEE802.11 standards and cellular GSM and CDMA systems are now widely used in homes or for enterprise applications.
Wireless solutions have many advantages over wired solutions. For example, wireless eliminates wiring costs and increases mobility. Thanks to the development and maturity of wireless technology, industrial applications can now reap the benefits
 

GPRS is a communication technology that allows data acquisition systems to overcome the difficulty of cabling for wide area remote sites. GPRS applications are becoming more and more prevalent due to the ease with which they can be implemented, but the dynamic IP address issues associated
with GPRS networking continue to frustrate system integrators.

Wide temperature technology has enabled system integrators to deploy industrial computers in a greater range of indoor and outdoor environments.

What is GPRS I/O? How can GPRS I/O help?
GPRS I/O devices utilize GPRS communication technology to collect data from monitored devices. GPRS I/O provides maximum flexibility and accessibility for remote monitoring and alarm systems by offering measurement data in places where cables are not convenient or feasible, making GPRS I/O especially suitable for wide area deployment, such as unmanned site monitoring, riverside monitoring, and pipeline monitoring.
 

Tailored to Your Specific Needs

Availability, reliability, and security are critical to industrial and mission-critical network applications. Moxa provides a vast range of industrial Ethernet switches with a unique mixture of industrial-grade reliability, resiliency and network redundancy, seamless integrated security, and best price-to-performance ratio. The options of rack, panel, and DIN-Rail mounting versions allow users to choose the best possible installation to fit into any application environment. With the continued demands for application-specific Ethernet switches, Moxa's products are designed to meet or exceed the strict requirements of various environmental standards, such as DNV, Class 1 Div. 2/ATEX Zone 2, EN50155, and much more.
Core Competence

Field operational safety and adaptability is a matter of the utmost importance and cannot be compromised in hostile industrial environments. For this reason, engineers must ensure that all devices installed under critical operating situations meet stringent environmental requirements. Designed for peace of mind, most of Moxa's products are fully compliant with a wide range of industry standards to guarantee a high degree of adaptation to extreme field conditions, such as humidity, dust, corrosion, temperature, vibration, shock, and EMI Interference.

The Precision Time Protocol (PTP) is a time-transfer protocol defined in the IEEE 1588-2002 standard that allows precise synchronization of clocks across a network (e.g., Ethernet). Accuracy within the nanosecond range can be achieved with this protocol when using hardware hardward assist to manipulate timestamps.

"IEEE 1588 is designed to fill a niche not well served by either of the two dominant protocols, NTP and GPS. IEEE 1588 is designed for local systems requiring very high accuracies beyond those attainable using NTP. It is also designed for applications that cannot bear the cost of a GPS receiver at each node, or for which GPS signals are inaccessible."[1]

An embedded system is a computer system designed to perform one or a few dedicated functions,[1] often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. In contrast, a general-purpose computer, such as a personal computer, is designed to be flexible and to meet a wide range of an end-user's needs. Embedded systems control many of the common devices in use today.

Gas pipeline tunnel’s temperature monitoring is crucial for the operation safety. In a confined space, temperature rises easily. The overheating might case the fracture of pipeline that can lead to gas leakage and possible explosion, so the temperature needs to be monitored closely. However, the unique long shape of tunnel means that more home run cables must be made to link every I/O data acquisition device back to the SCADA.

GT-530 is an intelligent SMS controller for industry applications with the simple commands and SMS tunnel function, and power can be input by the external power or Li-Battery. It supports UNICODE or 7 bit format for users to implement sending SMS messages with various languages. Applying GT-530, the SMS reports can be sent by defined time or DI/counter event trigger. This can be a remote control and alarm system allowing you to use your mobile phone to monitor and control your business from any location. Its alarm facilities provide a flexible way to distribute critical alarm information to any number of mobile phone users. GT-530 can monitor total 10 digital inputs (6 counters). The users can interrogate the status of I/O through SMS messages. GT-530 also has 2 Digital output which can be activated via DI trigger or SMS to control the lamps, pumps, heaters etc.

If you're still using NTP, IRIG-B, or other protocols that fail to provide time accuracy down to the nanosecond level, you're probably spending more time and money than you need on synchronizing your substation automation system (SAS). These outdated solutions generally require engineers to set up and maintain a separate and dedicated network to synchronize all the nodes in the power grid.
