STR551- Pixsys® display 96×48


The STR551 universal indicator is designed for process acquisition and retransmission. The analogue input can be configured as a parameter for a wide range of temperature and process signals in mA and Volt. The monochrome OLED graphic display supports process trend visualizations with settable sampling time and bargraph representation with thresholds for level, flow and metering measurements. The linearization of the entrance is customizable up to a maximum of 16 points, useful on tanks with an irregular profile. Mathematical functions related to the process are also implemented, such as Totalizer and Sum. Connectivity is guaranteed by the RS485 standard with Modbus RTU / Slave protocol. For maximum flexibility of use it is also possible to choose between horizontal or vertical installation. A distinctive feature that characterizes the entire STR series is the innovative multilingual interface, with text menus that allow intuitive and fast navigation between parameters and display pages. You can choose between five languages and the completeness of the menus allows you to considerably limit the need for consultation of the technical documentation for the initial setting.
