Load0 ... 600 Ω
Output signal4 ... 20 mA (overload > 25 mA)
Ripplemax. 50 µA rms
External supply (loop)2 ... 30 V DC
If the external voltage is > 19 V, a load ≥ ((V - 19) / 0.02) Ω is required. V represents the value of the external voltage.
The internal 250 Ω resistor at terminals 9 and 12 can be used as a load.
