CE is a mandatory standard for products on the market in the European Economic Area. By CE marking a product, the manufacturer ensures that the item meets the essential safety requirements set out in the applicable CE directive.
This product fully adheres to the Restriction of Hazardous Substances Directive 2002/95/EC, RoHS for short.  The directive covers the restriction of use of certain hazardous substances in electrical and electronic equipment and was adopted in February 2003 by the European Union.
Underwriters Laboratories (UL) is an independent product safety certification organisation based in the United States. UL develops standards for products, materials, components, assemblies, tool and equipment, mainly dealing with product safety.
IEEE 1613 Environmental and testing requirements for communications networking devices in electric power substations.
These devices and systems have been designed to accept a wide voltage DC power input. This feature is desirable in the industrial market where a fixed voltage level or mains AC power cannot be guaranteed.
The Federal Communications Commission (FCC) is an independent agency of the United States government that sets standards and governs the testing of conducted and radiated emissions such as EMI.
These products utilise high quality industrial grade components enabling them to work in extended wide temperature environments. They are capable of running below -20C and above +70C and offer further protection than standard wide temperature rated products.
These products come with a standard five year manufacturer warranty.

NPort S9650I-8 overview

  • Supports up to 4x managed Ethernet switch ports (fibre available with some optional network modules)
  • 8-port RS-232/422/485 serial interface
  • Supports DNP3 and Modbus protocols
  • Ethernet redundancy with Turbo Ring/Chain and RSTP/STP supported
  • Real COM/TTY drivers for Windows and Linux
  • IEC 61850-3, IEEE 1613 (power substations) compliant
  • IEEE 1588v2 and IRIG-B time synchronization functions
  • Supports IEC 61850 MMS protocol
  • Security features based on IEC 62443/NERC CIP
  • -40°C to +85°C extended operating temperature
The NPort S9650I-8 8-port serial device server comes with a fully functioning built-in 4-port managed Ethernet switch is designed specifically for the harsh environments found in electrical substations. By combining the Ethernet switch and serial device server, the NPort S9650I's serial devices can be easily installed, maintained and managed. The Nport S9650I-8 has an extended wide operating temperature range of -40°C to +85°C and galvanised steel housing with dual power supplies for redundancy and accepts a high voltage power input of 88V to 300V DC and 85V to 264V AC. 

The NPort S9650I-8 uses power SCADA to control and monitor both comms devices (switches, routers, etc.) and Intelligent Electronic Devices (IEDs) with the MMS protocol compared to the more traditional approach of using SNMP for comms devices and MMS for IEDs. Furthermore, NPort S9650I range are the world’s first device servers to integrate MMS into an IT-type device designed specifically for power SCADA applications. The NPort S9650I even supports using MMS to monitor serial communications between the S9650I and legacy devices.

The NPort S9650I-8 is designed to integrate Modbus TCP, ASCII and RTU devices in almost any master/slave combination including simultaneous serial and Ethernet masters. Moreover, NPort S9650I-8 serial device servers also supports protocol conversion between DNP3 serial and DNP3 IP, and all models are ruggedly constructed to ensure reliable operation.

The NPort S9650I-8 has security features based on IEC 62443/NERC CIP to provide a high level of cybersecurity. Protecting mission-critical networks from cyberattacks is a high priority for industrial automation applications which can suffer large losses due to extended network downtime. IEEE 1588v2 is used as a time source and converted to IRIG-B for distribution to the IEDs via the serial ports or via a dedicated IRIG-B BNC connector. 

The NPort S9650I-8 integrates a full-function NPort device server with an industrial switch to carry serial and Ethernet devices at the same time. In addition, the NPort S9650I-8 offers ring redundancy with standard STP/RSTP and Moxa’s proprietary Turbo Ring or Turbo Chain 2 redundancy protocols.
