NOTICE
Protection from overvoltage
If the PT100 operating mode is selected, the hardware is protected against overvoltage. The
following mechanisms are triggered in the event of an error:
1. An error bit is set which is then communicated to the PLC.
2. The module is shut down.
Measurement using a 4-wire connection system
Notes regarding the connection and operation of PT100 resistors:
This enables the module to supply X3 with a constant current via the CO1, CI1, CO2 and CI2
terminals. The constant current is fed to the resistor to be measured where it is then measured
as the voltage drop. It is imperative to wire the connected constant current cables directly to
the resistor.
