The Label Tab A label can be positioned on the tab shown above in item 1 to help identify the
module that will reside at this base unit’s island bus location. A similar label can be
placed on the PDM itself so that they can be matched up properly during the island
installation.
Labels are provided on an STB XMP 6700 marking label sheet, which can be
ordered at no charge from your Scneider Electric service provider.
The Island
Bus Contacts
The six contacts located in a column at the top of the I/O base allow island bus logic
power and communication signals flow through the PDM downstream to the I/O
modules:
1 not used
2 common ground contact
3 5 VDC logic power contact
4 island bus communications + contact
5 island bus communications - contact
6 address line contact
The STB PDT 3100 and STB PDT 2100 PDMs are non-addressable modules, and
they do not use the island’s logic power or communication buses. The six island bus
contacts at the top of the base are used for 5 V ground and for LED power.
