Digital indicator table 96×48 mm with OLED screen
Universal input, 2 relays, analog outputs, RS485
The STR551 from Pixsys is a digital 96×48 mm table display. 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.
The input accepts thermocouples, thermoresistors, thermistors, 0…10 V signals, 0/4…20 mA signals, 0…60 mV signals, and potentiometers. A linearization up to 16 points allows the display to be adapted to non-linear sensors.
Two 2 A relays manage the alarm thresholds, in absolute mode, band, delayed or stored mode. Two analog outputs 0…10 V and 0/4…20 mA transmit the measurement to an automation system or recorder.
The totalizer, time-based sum function, trend recording, and customizable measurement units make the STR551 much more than just a simple display.
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.
DYNATIME SA distributes the Pixsys indicators in Switzerland. For a force or weight measurement, see the STR561, and for displaying Modbus variables, the STR571. Contact us for advice or a quote.
