Moxa NPort S8455I-MM-SC combination ethernet switch and device server

Click2Contact

Moxa has released the NPort S8455I-MM-SC, the first model in the NPort S8000 series, which combines an ethernet switch and serial device server in a single unit with two fibre ethernet ports, three copper ethernet ports and four RS232/422/485 serial ports.

The device is a suitable solution for remote monitoring and control applications, due to its compact size and all-in-one switch/device-server design. Renewable energy markets, such as solar power plants and wind farms, also benefit from the increased reliability and availability offered by it’s ethernet redundancy function and ring topology support.

The device supports all of the NPort 5000 series device server functions. Users can network existing serial devices by connecting up to four serial devices through each of the five ethernet ports, with only basic configuration required. Data transmission between the serial and ethernet interfaces is bidirectional.

It 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. Ethernet redundancy is provided by Moxa’s turbo ring technology (recovery time: 20 ms) or RSTP/STP (IEEE 802.1w/D).

It may be inconvenient to use one large ring for redundancy if the network devices are remote and spread out. The device’s ring-coupling feature solves this issue by connecting distributed devices into smaller, more manageable turbo rings that can still communicate with each other without a control line.

The device comes with UL508 safety, serial, ethernet, and fibre three-way surge protection, level 4 ESD protection and 2 kV serial isolation.
