Maximum permanent allowed overload (no damage)
Current input When the input current exceeds the
overflow value of the measurement
range, the input impedance is switched
to high impedance for protection. The
maximum allowed overload is then 30
V. The digital value corresponds to the
overflow value. Periodically, the input
impedance is switched to the normal
value and the input current is measured.
If the input current is within the meas-
urement range, the input impedance
remains at the normal level and the dig-
ital value corresponds to the measured
current.
Voltage input 30 V
