Remember the isolation amplifier
If signals are received from different controls, e.g. heat re-
covery for one of the inputs, a galvanically insulated module
should be inserted.
Active at
The function of the switch functions can be seen in the last column.
There are pressure transmitters AKS 32R and AKS 2050 available for
several pressure ranges.
Here there are two different ones. One up to 59 bar and two up to 159
bar.
