Overview

The NPort® S8000 series combines an industrial device server with a full-function managed Ethernet switch by integrating 2 fiber ports, 3 Ethernet ports, and 4 RS-232/422/485 serial ports, allowing you to easily install, manage, and maintain the product. Combining a device server and switch in one product allows you to save space in your cabinet, reduce overall power consumption, and reduce costs, since you will not need to purchase a switch and serial device server separately.

Supports all NPort® 5000 Series Device Server Functions

The NPort® S8000 series supports the complete array of NPort® 5000 series device server functions. You can network your existing serial devices by connecting up to 4 serial devices through each of the 5 Ethernet ports, with only basic configuration required. In addition, data transmission between the serial and Ethernet interfaces is bi-directional.

Full-function Managed Ethernet Switch

The NPort® S8000 series has a built-in full-function managed Ethernet switch that supports QoS, IGMP-snooping/GMRP, VLAN, Port Trunking, SNMPv1/v2c/v3, and IEEE 802.1X, allowing you to handle virtually any kind of application. Ethernet redundancy, which is used to increase the reliability and availability of your industrial Ethernet network, is provided by Moxa's own Turbo Ring® technology (recovery time < 20 ms) or RSTP/STP (IEEE 802.1w/D).

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. A significant part of this type of communication depends on ring redundancy at the device level, which is designed to provide fast network fault detection and reconfiguration in order to support the most demanding control applications.

The NPort S8000 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 S8000 can also achieve ring redundancy with standard STP/RSTP and Moxa's proprietary Turbo Ring or Turbo Ring 2 redundancy protocols. This all-in-one design can be used to optimize and simplify your device network, and enhance reliability.

Details

Couple Several Turbo Rings for Distributed Applications

For some systems, it may not be convenient to connect all devices in the system to create one BIG redundant ring, since some devices could be located at a remote site. The NPort® S8455I-MM-SC supports Turbo Ring's "Ring Coupling" function, which allows you to separate distributed devices into different smaller redundant rings, without a control line, and in such a way that the smaller rings will still be able to communicate with each other.

Rugged Design with Complete Protection

1. UL508 safety
To meet customers'critical application requirements, the NPort S8455I-MM-SC has been certified to meet the UL 508 national and international standard. The UL 508 standard covers the safety requirements for industrial control equipment.
2. 3-way surge protection
The NPort S8455I-MM-SC is equipped with a surge protector for power, Ethernet interface, and serial interface for protection against voltage spikes.
3. Level 4 ESD
The NPort S8455I-MM-SC supports high level, 8/15 KV, ESD protection to avoid damage from static electricity.
4. 2 KV Serial Isolation
Each serial port is protected by 2 KV of isolation against harmful currents from high voltages caused by a difference in ground potential between points in a communications system.

Typical Applications

Roadway Traffic Monitoring and Control

Intelligent transportation systems (ITS) are playing a major role in modern transportation construction, with ITS technology applied to roadway traffic control systems. In general, ITS involves integrating communication, control, and electronics technologies, and is used to monitor and manage traffic flow, reduce congestion, provide alternative routes to travelers, and enhance productivity to save lives,time, and money. Traffic monitoring and control systems are usually housed in a small cabinet located by the roadside or at an intersection.
Such systems usually include a camera for monitoring traffic, a traffic light control system, as well as other devices. The NPort S8455I-MMSC is the best choice for traffic monitoring and control applications, since the compact size and all-in-one switch/device-server design saves a significant amount of space in a small cabinet.

Solar Power Station

IAll solar power stations include three major devices—a power inverter, a PLC, and meters. The power inverter converts the energy generated by the plant into the power that is transmitted to end-users.
The PLC controls the sun tracking system of the base. These devices are often serial devices, although some may be Ethernet-ready. Now you can connect all of these Ethernet and serial devices to the control center easily and economically with one With the NPort® S8455I-MMSC. The Ethernet redundancy function and ring structure increase the reliability and availability of the system. The NPort® S8000 series is definitely the best solution for this type of solar power system.
