Note that voltage and current are
daisychained from either the
adapter, 1734-FPD module, or
1734-EP24DC module.
Common connections for three-
wire devices require an external
wiring connection. A 1734-CTM
module can provide the common
connection.

If a common connection is required (three-wire devices), then a 1734-CTM common terminal module
can be required.
