Pin assignment of the BaseUnit BU type B0
To connect to or use an existing potential group, you must use the following BaseUnit.
A new potential group is not created with the BaseUnit BU type B0 (BU20-P12+A4+0B /
6ES7193-6BP20-0BB0). It continues the potential group. The self-establishing voltage
busbars P1, P2 and the AUX rail are looped through to the neighboring module (BaseUnit)
on the left.
All 24 V nominal power supplies of the I/O circuits must only be powered by approved
sources that fulfill the requirements according to EN61010-2-201 for SELV, PELV, Class 2,
voltage limited and/or power limited sources.
