7.2.3 Connections/Cables for the Modular Connector Unit MA 90
The connector unit MA 90 is suited for connecting the BCL to peripherals (distributor function) and
power supply in industrial applications. This unit makes it possible to implement a direct connection to
the host (point-to-point) and an integration in the Leuze network.
Figure 7.1 shows an example of the principle of connecting the MA 90 to a BCL.
Figure 7.1: Block diagram: connecting the BCL to the connector unit MA 90
Connecting the BCL 90 to the MA 90:
Two cables KB090-3000 No. 500 35 319 are required to connect the BCL. An alternative connection
path can be via the external parameter memory KB090-3000P No. 500 35 322.
a) BCL without heater:
Connector unit MA 90
The cables KB090-3000 No. 500 35 319 can be extended to up to 10 m (terminal interface: RS 232!).
b) BCL with heater
Connector unit MA 90
The cables KB090-3000 No. 500 35 319 may not be extended!
If greater lengths are required, the power supply (pin 1/pin 5) are to be wired with a total core cross-
section of at least 0.75 mm² at max. 10 m length.
Recommendation!
Use cable KB090-3000H No. 500 35 324
(with two plug covers, length 3 m) for the connec-
tion.
