C Universal Temperature Converter Installation Instructions
If a current output is operated as a sink, the voltage across the terminals must be between 5 V and
30 V. An additional resistance is only required if the voltage is above 16.5 V. The resistance must 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
