Software-controlled, the CMC600 transfers the
switching status of its physical “Aux In 1” input
automatically via the cable to the serial Aux data
interface of the RFU630.
The RFU630 converts the status internally to its
logical “External input 1“.
Ratings for “External input 1”
("Aux In 1“ switching input)
Switch S6: SGND-GND
ON:
GND of the sensor connected to GND
of
CDM420-0006/CMC600.
OFF:
GND of the sensor connected to SensGND of
CDM420-0006/RFU630 (electrically isolated
to the CDM420-0006/RFU630).
Selected reference potential valid for all switching
inputs ( “Sensor 1/2” and “Aux In 1/2” )
Function assignment to "External input 1" via SOPAS:
- Start of reading clock
- Stop of reading clock
- if required further functions in the future
Power fed to the input starts the
assigned function, e.g. start of reading
clock.
(default setting: logic not inverted
[active high], debouncing 10 ms)
– Optodecoupled, reverse polarity
protected
– Can be wired with the PNP output of
a sensor
– SensGND is the shared isolated
ground of all switching inputs
