12.2 PP 72/48D PN and PP 72/48D 2/2A PN
Analog inputs
The module has two analog inputs. These can optionally be assigned parameters as voltage,
current or PT100 input.
• "Voltage input" operating mode:
• "Current input" operating mode:
• "PT100" operating mode
Note
The analog inputs are only enabled following the parameter assignment.
Cycle time of the analog value accumulation: 20 ms per channel
NOTICE
Protection from overvoltage
If the PT100 operating mode is selected, the hardware is protected against overvoltage.
In the event of an error the following occurs:
1. An error bit is set which is then communicated to the PLC.
2. The module is shut down.
