575F

Large field-display with microprocessor technology

The large field display series 575 for serial communicationis designed for applications where a readability of 20 to 100metres is required. Configuration is easy with keys and a 5digit minidisplay inside the case. The displays use the simpleNokeval SCL protocol where only the address, value and check sumare sent. The displays come standard with both the serial inputsRS-232 and RS- 485. The serial bus is galvanically isolated fromthe processor and the power supply. In the configuration mode youcan set the address, baud rate and the type of number value thatyou want to appear on the display after power connection.
