Multiple function of the analog and digital inputs

Analog inputs 1 and 2
The analog inputs have several functions:
● Under "P-ANALOG INPUTS/Analog input 1/AI-function" you can set the value from
● Under "P-ANALOG INPUTS/Analog input 2/AI-function" you can set analog input 2 from
● Also adjust the corresponding DIL switches of the -S2 switch row on board CB08
● More detailed information can be found in the section "DIL switches S1 and S2 (Page 101)".
The following functions are now available:
● "Analog":
● "PTC":
● "KTY84":
● "PT100":
Any analog input can only be used for one function. It is not possible to use several functions
simultaneously for one input.
Digital inputs ‑X2:27 and ‑X2:28 as PTC thermistor inputs
The digital inputs are interpreted as a normal digital input for control with a 24 V signal. If these
control cable terminals are wired to 10 V potential using a PTC thermistor sensor, these

"Analog" to "PTC", "KTY84" or "PT100".
The analog input operates as a voltage input at control cable terminals ‑X2:52‑51 / 54‑51
or as a current input at control cable terminals ‑X2:50‑51 / 53‑51 The value is available as
"AI 1" or "AI 2" for further processing.
The analog input operates as a PTC thermistor input at control cable terminals
‑X2:50‑51 / 53‑51. The PTC thermistor status is available for further processing as selection
bit as "PTC AI 1" or " PTC AI 2"
The analog input operates as a direct input for a KTY84-130 temperature sensor at control
cable terminals ‑X2:50‑51 / 53‑51. The measured temperature is available as an analog
value under "T‑AI1" or "T‑AI 2" for further processing.
The analog input operates as a direct input for a PT100 temperature sensor at control cable
terminals ‑X2:50‑51 / 53‑51. The measured temperature is available as an analog value
under "T‑AI1" or "T‑AI 2" for further processing.
