External 24VDC Wiring Options
DC output and analog I/O modules do not have direct access to the internally bussed 24VDC.
External user supplied 24VDC power, or auxiliary 24VDC from the T1K-01AC, can be
applied directly to one end of the DC I/O module base terminal (V and COM) rows and
jumpered across each base as needed in a system. This creates a “bus” (row) of 24VDC and a
bus of 0VDC power. Be sure not to exceed the supply’s power budget.

base to another as necessary to continue
the external 24VDC power bus.
Use an external 24VDC power supply to
