Phox sensor with integrated Pt1000 sensor measures irradiance and cell temperature. Other commercially
available sensors as e.g. ISET-Sensor® can be connected using a reliable cable connection.
Pinout of sensor plugs:
10.2 Pin allocation of the sensor connections:
Allocation until 2003
Irradiance: 5pin female chassis socket B605 (plug:M605)
Pin 1 = not used
Pin 2 = V+
Pin 3 = not used
Pin 4 = V-
PIN5= not used
Temperatur: 6pin female chassis socket -B606 (plug:M606)
Pin 1 = +Current source (~1 mA)
Pin 2 = +Pt1000
Pin 3 = not used
Pin 4 = - Pt1000
Pin 5 = - Current source
Pin 6 = not used
Allocation 2003 - 2008:
Temperature: 4 pin female chassis socket Lumberg KFV40 (plug SV40)
Pin 1 = Current source + (~1 mA)
Pin 2 = Pt1000 +
Pin 3 = Pt1000 -
Pin 4 = Current source - (~1 mA)
Irradiance: 3 pin female chassis socket Typ Lumberg KFV30 (plug: SV30)
Pin 1 = V+
Pin 2 = not used
Pin 3 = V-
Allocation starting from 2008:
Temperature (external): 4 pin female chassis socket Lumberg KFV40
Pin 1 = Current source + (~1 mA)
Pin 2 = Pt100 +
Pin 3 = Pt100 -
Pin 4 = Current source - (~1 mA)
Irradiance: 8 pin female chassis socket Lumberg KFV81 (plug: SV81)
Pin 1 = Irradiance+
Pin 2 = Pt1000 (reference) +
Pin 3 = Irradiance-
Pin 4 = Current source + (~1 mA)
Pin 5 = Current source - (~1 mA)
Pin 6 = do not connect
Pin 7 = do not connect
Pin 8 = Pt1000 (reference) -
