TU-RS485-ETH-DL-IO is an Intelligent unit able to control a network of slave Modbus RTU devices connected on serial line RS-485 Master executing the reading and writing of the field values and performing the logical and mathematical functions necessary for the system working, managing up to 8 task of recording memorized on files saved on USB Memory Key. The device is equipped with 4 digital inputs channels and 2 relay outputs. For the digital inputs, are also available 32 bit counters and the measure of the frequency up to 300 Hz.
By means of the Ethernet interface or the RS-485 “SLAVE” or RS-232 ports it is possible to read and write, in real time, the internal registers value. By Ethernet it is possible to get access to the files saved on the USB Memory Key when the Data-Logger function is active. Moreover, by means of the Ethernet interface, or by the RS-485 “SLAVE” or RS-232 ports it is possible to:

• Programming of the Control Logic
• Monitor, request of data, programming in real time the Intelligent Unit
• Direct programming and request of data from the Slave devices connected on the RS-485 Master.

The device TU-RS485-ETH-DL-IO is configurable by the software, an easy and intuitive free IDE developed by CD Automation and running under Windows.
The device realizes a full electrical isolation between the lines, introducing a valid protection against the effects of all ground loops eventually existing in industrial applications.
