The Current/Voltage Isolator converts a high-level current and a high-level voltage (ac or dc) into two low-level (0 to ±10 V) output signals, electrically isolated from the high-level signal source. This allows observation of the signal waveforms in power circuits using a conventional oscilloscope. The output signals can also be used in control circuits as current or voltage feedback signals.

The isolated signal at the current output (I) is proportional to the input current. Similarly, the isolated signal at the voltage output (E) is proportional to the input voltage. Both isolators can be used simultaneously. Model 9056-1 is designed to be used with 0.2 kW EMS systems.

The Current/Voltage Isolator is a plug-in module designed to be inserted into the Enclosure / Power Supply, Model 8840. It is automatically powered when it is inserted into the enclosure.
