5.10 Technical data for the ±5VDC voltage input
This input is used to acquire additional voltage signals.
Connect a signal converter to the input. This can be used to
acquire any AC or DC currents which are converted by the
converter into an electrically isolated ±5 V signal. This ±5 V
signal is processed by the module.
Connection example: Figure 13
Tolerances of the voltage input
Typical tolerance values are measured application values
that are based on the maximum variance of all test objects.
The maximum tolerance values represent the worst-case
measurement inaccuracy. They contain the theoretical max-
imum possible tolerances in the corresponding measuring
ranges as well as the theoretical maximum possible toler-
ances of the calibration and test equipment. The data is valid
for at least 24months from delivery of the module. Thereaf-
ter the modules can be recalibrated by the manufacturer at
any time.
Use an isolating amplifier to decouple from the field the sen-
sor signals which go to the sensor input. The MCR range
from Phoenix Contact offers various solutions (see also con-
nection example "Universal AC and DC current acquisition
by means of combination with a current transducer").
