Operating Instructions
Transducer for AC current SINEAX I 542
2. Brief description
The transducer SINEAX I 542 is designed to convert a
sinusoidal AC current into a DC current or voltage signal
proportional to the measured value. It does
not
require a
separate power supply.
Safety precautions to be strictly observed are marked
with following symbols in the Operating Instructions:
