Main Module Connectors
These connections provide duplicate terminals for twin, wide ranging DC
supplies (24V nominal).

You can use the duplicate terminals to daisy chain the power from one base to
the next (subject to an overall current limit and using a star connection to avoid
excessive voltage drop). There is internal diode protection against reverse
polarity and for the purposes of automatic supply selection when redundant
sources are connected to inputs 0 and 1. The supply side connections are
isolated from the remainder of the module circuitry.
