Datexel Isolated Module Modbus RTU with Digital IO and micro SD Ram card - DAT9000-DL-IO-2.0

N.4 Digital Inputs + N.2 SPDT relays, Master both on RS-485, EMC compliance – CE mark, DIN rail mounting - High Quality

The device DAT9000DL-IO-2.0 is an Intelligent unit able to control a network of slave Modbus RTU devices connected on serial line RS-485 Master or Modbus TCP through the Ethernet interface executing the reading and writing of the field values and performing the logical and mathematical functions necessary for the system working, managing up to 10 task of recording memorized on files saved on the microSD card. The device is equipped with 4 digital inputs channels and 2 relay outputs. A 32-bit pulse counter is available for each digital input.

By means of the Ethernet interface or the RS-485 “SLAVE” or uUSB 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 SD card memory when the Data-Logger function is active.

The supplied CVPROG cable allows you to configure / program the device without using an external power supply.

Moreover, by means of the Ethernet interface, or by the RS-485 “SLAVE” or uUSB 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 to the RS-485 Master.

The device DAT9000DL-IO is configurable by the software DEV9K 2.0 and successive versions developed by DATEXEL and running under Windows.

The device DAT9000DL-IO realizes a full electrical isolation between the lines, introducing a valid protection against the effects of all ground loops eventually existing in industrial applications.

LED signaling of Ethernet activity and data Rx-Tx flow 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).

The device is housed in a rough self-extinguishing plastic enclosure which, thanks to its thin profile of 22.5 mm only, allows a high density mounting on EN50022 standard DIN rail.
