The NPort S9450I Series 4-port RS-232/422/485
device servers, which come with a built-in full-function managed Ethernet
switch, are designed specifically for the harsh environmental conditions
found in electrical substations. With both fiber and wired Ethernet
ports supported, the combination of device server and Ethernet switch
gives users the ability to easily install, manage, and maintain the
NPort S9450I itself, as well as attached serial devices.
Electromagnetic Compatibility for Harsh Substation Environments
The NPort S9450I Series supports a high level of surge protection to prevent damage from the types of power surges and EMI one finds in electrical substations and industrial automation applications. Combined with a -40 to 85°C operating temperature range and galvanized steel housing, the NPort S9450I is suitable for a wide range of industrial environments.
Another plus is the NPort S9450I’s dual power supplies, which provide both redundancy, as well as a wide range of voltage inputs. The WV models accept a power 24/48 VDC power input (ranging from 18 to 72 VDC), and the HV models accept a power input of 88 to 300 VDC and 85 to 264 VAC.
Power SCADA With IEC 61850 MMS for Easy Maintenance
The current trend in power SCADA applications
is to control and monitor both IT devices (switches, routers, etc.)
and IEDs (sensors, actuators, etc.) with the MMS protocol. Contrast
this with the more traditional management approach of using SNMP for
IT devices and MMS for IEDs. In fact, SIs may even need to manage
a variety of legacy devices that use proprietary communications protocols.
The NPort S9450I device
servers are the world’s first device servers to integrate MMS into
an IT-type device designed specifically for power SCADA applications.
The NPort S9450I even supports using MMS to monitor serial communications
between the S9450I and legacy devices.
Supports Modbus/DNP3 Protocol Gateway
The NPort S9450I Series provides maximum flexibility for integrating industrial Modbus/DNP3 networks of all types and sizes. The NPort S9450I is designed to integrate Modbus TCP, ASCII, and RTU devices in almost any master/slave combination, including simultaneous serial and Ethernet masters.
The NPort S9450I device servers also support protocol conversion between DNP3 serial and DNP3 IP. All models are ruggedly constructed and are DIN-rail mountable.
Ring Redundancy at the Device Level
Device-level communication networks for industrial automation are very critical since they are used to control and monitor device processes. The reliability of these communications depends on ring redundancy at the device level, which is designed to provide fast network fault detection and reconfiguration to support the most demanding control applications. The NPort S9450I Series 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 S9450I can also achieve ring redundancy with standard STP/RSTP and Moxa’s proprietary Turbo Ring or Turbo Chain 2 redundancy protocols. This all-in-one design can be used to optimize and simplify your device network and enhance reliability.

Note: When connecting a single-mode fiber transceiver, we recommend using an attenuator to prevent damage caused by excessive optical power. Note: Compute the “typical distance” of a specific fiber transceiver as follows: Link budget (dB) > dispersion penalty (dB) + total link loss (dB).
