I have a 0-16 bar pressure probe connected to a module called Adca UD-720. The probe works on a 4-20 mA loop and the readings are ok. This module also has a 4-20 mA output and I need to connect this output to a data acquisition module in order to get the readings remotely. But when I connect the output to the module, the module goes into protection mode. When I measured the output I couldn’t read any current, but I got a 14.7 voltage, which is way too high. The module can only support an input up to 10 V.
So, how can I reduce the voltage below 10 V, and still be able to read the current? i was thinking to use resistors, but i do not know what resistors to use.
