Its OLED graphic display displays the measured value, a trend or a bar graph, with clear text menus available in French, German, Italian, English and Spanish.<\/p>\n<h3>Universal input 16 bits<\/h3>\n<p>The input accepts thermocouples, thermoresistors, thermistors, 0\u202610 V signals, 0\/4\u202620 mA signals, 0\u202660 mV signals, and potentiometers. A linearization up to 16 points allows the display to be adapted to non-linear sensors.<\/p>\n<h3>Alarms and broadcasting<\/h3>\n<p>Two 2 A relays manage the alarm thresholds, in absolute mode, band, delayed or stored mode. Two analog outputs 0\u202610 V and 0\/4\u202620 mA transmit the measurement to an automation system or recorder.<\/p>\n<h3>Calculations functions<\/h3>\n<p>The totalizer, time-based sum function, trend recording, and customizable measurement units make the STR551 much more than just a simple display.<\/p>\n<h3>NFC and Modbus configuration<\/h3>\n<p>The indicator is configured via NFC with the MyPixsys application without being powered, or via micro USB. The isolated RS485 port in Modbus RTU connects it to the supervision system.<\/p>\n<h3>Typical applications<\/h3>\n<ul>\n<li>Displaying temperature, pressure, level or flow on the front of the cabinet<\/li>\n<li>Threshold monitoring with relay alarms<\/li>\n<li>Transmission of a measurement to an automated system<\/li>\n<li>Replacement of the STR550, whose successor is the STR551<\/li>\n<\/ul>\n<h3>Your process indicator in Switzerland with DYNATIME<\/h3>\n<p>DYNATIME SA distributes the Pixsys indicators in Switzerland.
