The table below lists the output signals:
The measured samples are governed by the following function:
I
0
= 4m A, MV = measured value (°C, % or rH%)

I
max
= 20m A, MB = measurement range
The meaning of the output signals is explained in the table below:
The four 4-20 mA output signals are broken out onto a detachable, 8-pin terminal block (3,5 mm /
0.14 inch). The mating connector is delivered as a standard accessory. The pin-out can be taken from
the following table.

Parameters marked with an asterisk “*” are only output if the respective option is installed.
Current Significance
4 mA The measured value is smaller than or equal to the lower boundary of the
measurement range.
20 mA The measured value is greater than or equal to the upper boundary of the
measurement range.
2 mA The unit is fully functional, but there is no valid measured value available (for
example, the optional sensor is not installed, the unit is still in the warm-up
phase, or similar.).
