Ratings for “Sensor 1” switching input
Switch S3: SGND-GND
ON:
GND of the sensor connected to GND of
CDB650-204/RFU630.
OFF:
GND of the sensor connected to
SensGND
of
CDB650-204/RFU630
(electrically isolated to the CDB650-
204/RFU630).
Selected reference potential valid for all
switching inputs (“Sensor 1/2” and “In 1/2”).
