Point Expansion or Conversion
AO-P Transducer
The AO-P Transducer converts field panel voltage output or current output to
pneumatic output.
Recommended maximum wiring runs for the AO-P Transducer Remote Mount (545-
208) and the AO-P Transducer Panel Mount (545-113) are listed in table AO-P
Transducer Remote Mount and Panel Mount Wiring Run Limitations.
