a) Sensor supplied by CDB620-001
b) Sensor connected electrically isolated and externally supplied
d) Switch connected electrically isolated and externally supplied
c) Switch supplied by CDB620-001
Serial Aux
(RS-232)
Function assignment to "External input 2" via SOPAS:
- Start of reading clock
- Stop of reading clock
- If required further functions in the future
Switch S3: SGND-GND
ON: GND of the sensor connected to GND
of CDB620-001/CMC600.
OFF: Sensor connected electrically isolated
to the CDB620-001/CMC600.
Reference potential valid for all switching
inputs ("Sensor 1/2" and "In 1/2")
Ratings for "External input 2"
("In 2“ switching input)
Power fed to the input starts the
assigned function, e.g. stop of reading
clock.

Software-controlled, the CMC600 transfers the
switching status of its physical "In 2" input
automatically via the cable to the serial Aux data
interface of the RFH630.
The RFH630 converts the status internally to its
logical "External input 2“.
