Modbus to Ethernet converter and gateway for Modbus RTU

General Description

The Modbus Ethernet gateway DAT3580-MBTCP allows connecting the Modbus RTU devices of a RS-485 network to the Ethernet network through the Modbus TCP protocol.

By means of the Telnet interface, it is possible to configure all the Modbus TCP side options (IP address, subnet mask, etc..) and the Modbus RTU side options (baud rate, etc...).

The device guarantees a full isolation between lines, allowing the use even in heavy environmental conditions. DAT3000 series devices are designed to be easily mounted on DIN rail, optimizing the space encumbrance. The thermal dissipation allows the devices to be mounted side by side, allowing a relevant reduction of required. The connections are made by means of removable screw terminals, to simplify the handling of the devices.

LED signaling of Ethernet activity and data rx-tx on the serial line allows a direct monitoring of the system functionality. The connection is made by removable screw-terminals (supply and RS-485) and RJ45 plug (Ethernet).

DAT3580-MBTCP is in compliance with the 89/336/EEC directive on the electromagnetic compatibility.

The device is housed in a rough self-extinguishing plastic container which, thanks to its thin profile of 22.5 mm only, allows a high density mounting on EN- 50022 standard DIN rail.
