Frequency Converter HiD2891
If a current output is operated as a sink, the voltage of the terminals has to be between 5 V and 30 V.
An additional resistance is required only, if the voltage is over 16.5 V. The resistance has to be
between (U - 16.5 V)/0.0215 A and (U - 5 V) / 0.0215 A (see diagram).
Example: U = 24 V
(24 V - 16.5 V)/0.0215 A = 350 Ω
(24 V - 5 V)/0.0215 A = 880 Ω

Resistor range
If a current output operated as a source, the load resistance has to be between 0 Ω and 550 Ω (535 Ω
if the output current is between 4 mA and 20 mA).
