Information
Larger terminal blocks may be used to group multiple signals. The current
carrying capacity of the terminal block is thus, however, reduced (according
to derating curve of the terminal block manufacturer.)
The technical data for the terminals are contained in the technical data
sheet of the manufacturer of the female connectors.
