Display for serial input





The field display 2071 is designed for serial communication. It uses the simple Nokeval SCL protocol where only the address, value and check sum are sent. The display has both the serial inputs RS-232 and RS-485 as a standard. The serial bus is galvanically isolated from the processor and the power supply. In the configuration mode you can set the address, baud rate and the type of number value that you want to appear on the display after power connection.

In industrial environments use of the addressable serial signal RS-485 is always recommended. 31 displays can be connected to one bus and by using a serial data converter (721R), another 31 displays can be added on. The maximum distance of the bus is 1 km. Serial input RS-232 only accepts one display connected to the bus the maximum distance being 15 m.

The display has large 20-mm-high red LED digits, the readability of which is about 10 metres. Case protection rating is IP65.
