PM4000 U/I

Function
The I/O module PM4000 U/I provides inputs for measuring line voltage and line current.
● Voltage measurement
Either the supplied line-to-line voltage or the star voltage is measured (parameterizable)
The rms effective value is calculated from the measured values.
● Phase current measurement
Three current transformers can be connected to the module (L1, L2, L3). The rms
effective value is calculated from the measured values. The measuring accuracy depends
on the current transformers used.
The measured values are transferred via the fieldbus and can be evaluated and further
processed by the user.
