What it represents
A current signal isolator transfers a documented analog current input to an output while providing the specified electrical separation. Signal input, output and auxiliary supply are distinct terminal groups.
How to read it
- Determine active and passive current-loop roles at both interfaces.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- State input/output range
- Show separate commons
- Reference supply and isolation rating
A distinction that matters
Signal isolation is different from changing the power-system voltage with a transformer.
