Datexel RS485 Modbus Remote Display Programmable - DAT9550

Compact, Programmable, Italian Made

The device DAT 9550 is a graphic display designed for panel mounting and communicating with Modbus RTU protocol on RS-485 and RS-232 serial Slave port.

Moreover, on the device there is a RS-485 Master port by means of which it is possible to communicate with the eventual Modbus Slave devices connected.

It can be used as Slave peripheral for the visualization of the data coming from the Intelligent Units of the DAT9000 series or from a PC, PLC or panel operator.

By means of the Slave serial ports it is possible to configure, by software Dev9K, the graphic pages.

The device is equipped with buttons on the front panel by which it is possible to:

- set the communication parameters of the device such as baud-rate and Modbus address;

- set the levels of brightness and contrast of the display;

- set the values of the local variables selected from the user;

- scroll between the graphic pages.

The implementation of the device is easy and immediate: it must be fixed to the panel by screw terminals; for the connection on the rear side are used removable screw terminals to connect the RS-485 serial ports and the power supply; to connect the RS-232 port it is available a RJ45 connector.

It is housed into a robust plastic enclosure of 96 x 48 x 74 mm in compliance with the DIN43700 standard.
