External divider for analogue inputs and measurement range
±25 V or ±20 V
Anextendedmeasurementrangeof±25Vor±20Vcanbeachievedwithasym-
metricalexternalresistordivider.Therecommendedwiringappearsasfollows:

Theresistoraccuracyclassshouldbe(dependingonrequirements)0.1%to1%.
Inputimpedanceisreducedhereto25or20kΩ.Measuringpointscalingmustbe
increasedusingtheDataServiceConfiguratorPCsoftwarebythefactor2.5or2.0.
External AC coupling
ACcouplingcanbeachievedwithsymmetricalcapacitors.Therecommendedwir-
ingappearsasfollows:

Non-polarizedcapacitorsmustbeused.Theinputhigh-passhasacut-offfre-
quencyof4…0.4Hz.
ExternalACcouplingisusefulformobilesystems.Forfixedinstallations,referto
