Modbus 96×48 mm variable display with OLED screen
2 RS485 master/slave ports, 2 relay outputs
The STR571 from Pixsys is a portable display with a 96×48 mm format that interfaces with Modbus devices and displays their values on a graphic OLED screen. This is a simple solution for displaying data on the façade that is accessible only via the serial connection.
The STR571 reads up to 8 16-bit or 32-bit Modbus RTU variables, distributed over 1 to 4 variables per page. Names (16 characters) and units are customizable, and values can be scaled for display.
The first port interrogates the devices using Modbus RTU/ASCII master. The second, in Modbus RTU slave mode, allows an automation system or supervision system to interrogate the STR571 in turn.
Two 2 A relays manage alarms on the read variables. Three digital inputs and a potentiometer input allow changing values, triggering alarms, or navigating through the pages.
The display is configured via NFC with the MyPixsys app, via the keyboard or via micro USB with MyPixsysLab. The menus are available in French.
DYNATIME SA distributes the STR571 in Switzerland and helps you configure the reading of your Modbus registers. For a direct measurement of the sensor, see the universal indicator STR551.
