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.
