Can be ordered only via GMC-I Messtechnik GmbH,
see Catalog IC 10, Chapter 16 "Appendix
"External Partners"
2)
Not included in scope of supply of the 3RK1904-2AB02 addressing unit.
3)
For connecting the addressing unit to an AS-i network via AS-Interface
M12 feeder, a connecting cable (M12 plug to M12 connector) must be
produced and requires the following wiring:
- M12 cable plug: Pin 1 / core brown
M12 plug: Pin 1
- M12 cable plug: Pin 3 / core blue
M12 plug: Pin 3
- Pin 2, 4, 5 not connected.
