Power supply NG03 Description
The NG03 power supply is suitable for E-T-A Level sensors NR60,NR80, NR100, NR150 and NR160. It has a relay output with
adjustable switching delay which is controlled by the signal output of
the sensor. Status indication is by green LED. Power failure and wire
break are indicated in the same way as incorrect medium level (closed
circuit principle).
