Description

The Moxa NPort S8455I is an industrial serial device server with four RS-232/422/485 serial ports and a built-in managed Ethernet switch with five 10/100BaseT(X) copper ports. It connects existing serial devices to an Ethernet network with only basic configuration, and provides 2 kV isolation protection on each serial port. This standard-temperature model operates from 0 to 60°C on a 12 to 48 VDC power input.

The adjustable pull high/low resistor on the RS-485 ports and Serial QoS for prioritising serial data transmission make it well suited to industrial automation and field deployments where reliable serial-to-Ethernet connectivity is required. The all-copper five-port Ethernet switch allows daisy-chaining and local device connections without an additional switch.

Features

- Serial QoS for configuring serial data transmission priority
- 2 kV isolation protection for each serial port
- Adjustable pull high/low resistor for RS-485 ports
- Built-in managed Ethernet switch
- Needs only basic configuration to network existing serial devices
