Description

The SS8580 connects all devices with Modbus RTU of a RS-485 serial line to the Ethernet with Modbus TCP protocol.
By the integrated web server it is possible to configure the option of Modbus TCP ( IP address, subnet mask, etc..) and Modbus RTU (baud rate, etc…)

The SS8580 realizes a full electrical isolation against the effects of all ground loops. LED signalling for Ethernet activity, serial line communication and power supply allow direct monitoring of the system functionality. Connection is by removable screw-terminals (inputs and power supply) and RJ45 plug (Ethernet).

 The SS8580 is housed in a rough self-extinguishing plastic enclosure of 22.5 mm thickness, suitable for EN 50022 standard DIN rail.
