Connection unit MA 8-01
The modular connection unit is an optional accessory when connecting a BCL 8 to an RS 485 interface.
The RS 485 interface, the switching input and the switching output are all connected to the MA 8-01. It also
supplies voltage to the BCL 8. The MA 8-01 connection unit offers the following advantages over the instal
-
lation of the BCL 8 as a stand-alone device:
• M12 socket for switching input and switching output
• M12 connector for RS 485 interface and voltage supply 24VDC
• M12 socket for connection of the BCL 8
