Isolated External Current Control of Voltage Output
Background
Current control of the voltage output uses the
isolated current option (PSU-ISO-I). A current of
4~20mA is used to control the full scale voltage of
the instrument, where:
Output voltage = full scale voltage × ((external
current-4mA)/16mA)
Connection
When connecting the external current source to the
isolated analog option, use shielded or twisted
paired wiring.
