Signal converter for current / voltage, processes bipolar and monopolar analog signals, galvanic 3-way isolation

processes an active or passive analog input current of 0 mA to 20 mA or 4 mA to 20 mA and outputs it converted,
3-fold galvanic isolation

1- or 2-channel signal converters, process passive analog input currents from 4 mA to 20 mA and output them converted again,
galvanic isolation
