7.1
Current output
You can read out the measured values and the temperature as 0/4…20 mA signals via the current outputs.
With the setting 4…20 mA the resolution is lower, but defective cable connections are immediately evident.
With the parameters Begin and End you define which part of the measuring range you want to read out.
Alternatively you can use the current output as steady-state controller output. In that case assign the current
output to controller S1 or S2, respectively.
7.2
Serial interface RS485 (option)
The devices are available with serial interface RS485 by means of which they can be integrated in a data
bus system. Via the interface, all settings, measured and control values as well as any error messages can
be read out digitally.
Devices with RS485 are automatically delivered with the leaflet „Information on the RS485“ which contains
instructions on the communication and a complete list of the functions available via interface.
