  • Read up to 8 Modbus Addresses
  • Isolated RS485 Serial Port
  • Display 1 to 4 Variables Per Page with Auto Sizing
  • Configurable with NFC using the MyPixsys APP
  • Two Relay Outputs
  • Potentiometer Input
  • Multimaster  Mode
The STR571 indicator/panel meter is designed as a flexible and fully customizable display for sensors, I/O modules, signal converters, and for most instrumentation with an Modbus-RTU output signal.

The device allows up to eight variables to be read from or written to Modbus slave devices, with display of the variables in both numeric and textual formats. Both a description and measurement unit for each variable can be freely set in alphanumeric characters, and if necessary, the data can also be rescaled in display. The number of variables displayed per page can be set from 1 to 4, with auto rescaling of the font size and consequent number of pages.

In addition to the galvanically isolated Master serial port with Modbus RTU/Ascii protocol, a second Slave serial port makes querying from another Master possible.

The STR571 panel meter is also quickly configurable via NFC with MyPixsys APP, without the need to power up the instrument or via multilingual  text menus accessible by front keyboard.

Alarms and Relay Outputs
The STR571 has two relay outputs that can be set to activate on an alarm condition.  Alarm types include:
  • High or Low Setpoint Alarm with Hysterisis
  • Band Alarm - Activates/de-activates either within or outside a designated band
  • Serial Communication Failure

Digital Inputs
There are three digital inputs configurable as PNP or NPN.  The digital inputs may be used to:
  • Enable outputs
  • Reset alarms
  • Lock configuration
  • Increase/decrease values
  • Select values

Potentiometer Input
The STR571 has a potentiometer input.  This input may be used for setting a variable value.  The value can then be used to write to a slave device.
