3.3 Pt100 Connection
A Pt100 temperature sensor can optionally be connected to the four-pin connector (Binder series 711). The
possible measurement range depends on the Pt100 sensor and is max. -100...200 °C.
3.3.1 Unit Systems
The following unit systems are available for temperature measurement:
 °C
 °F
3.3.2 Simulator Value
When the simulator value has been activated, a defined simulator value is used instead of the current measured
value.
3.4 HC2 Connection
The PF4 optionally comes with a HC2 connection socket. It can be used for all HC2 probes in the ROTRONIC
portfolio. Alternatively, one pin of the socket can be used as analog current or voltage input. It must be
established on ordering the device whether the pin can evaluate current or voltage signals; it cannot be
reconfigured to do so later on (see chapter 6.4 ).
3.4.1 Unit Systems
The following unit systems are available for the HC2 connection:
 %RH

°C / °F
 mV / mA
