The analogue inputs can be set for the measurement of
– currents 0 – 20 mA or
– voltages 0 – 10 V.
A jumper is provided for this purpose beside the terminal strip for each
of the max. 3 inputs.
Standard configuration: Current measurement (I)
For voltage measurement (U) fit the related jumper. For this pur-
pose the cover with the cable clips must be removed: Undo
