3.8.6 6-5* Analog Output 1
Parameters for configuring the scaling and limits for analog
output 1, i.e., Terminal 42. Analog outputs are current
outputs: 0/4 – 20 mA. Common terminal (terminal 39) is the
same terminal and has the same electrical potential for
analog common and digital common connection. Resolution
on analog output is 12 bit.
6-50 Terminal 42 Output
Option: Function:
Select the function of Terminal 42 as an analog
current output. Depending on the selection
the output is either a 0–20 mA or 4–20 mA
output. The current value can be read out in
LCP in 16-65 Analog Output 42 [mA] .
