Approx. 2.5 W resp. ≤ 3 VA
500 Hz ... 35 kHz
– Open-circuit
Input current < 3.6 mA,
adjustable in the works
between 1 and 4 mA
– Short-circuit
Input current > 21 mA
adjustable in the works
between 20 and 23 mA
– Linear output signal
For an open-circuit output
0 mA (with 4...20 mA)
– 5 mA (with 0...20 mA)
For a short-circuit output
approx. 26 mA
– Increasing output signal
Output approx. 115% of
full-scale value, e.g. 23 mA
for output 0/4...20 mA or
11.5 V for output 0/2...10 V
– Decreasing output signal
(only possible for live zero)
Output approx. 10% of full-
scale value, e.g. 2 mA for
output 4...20 mA or
1 V for output 2...10 V
