140DDM69000 I/O 125 VDC Input/High Power Output Module
Overview The 125 VDC Input/High Power Output module provides four isolated outputs and
four grouped inputs. The outputs switch 24 to 125 Vdc powered loads and are for
use with sink and source devices. The outputs also have short-circuit sense,
indication, and shutdown circuitry. The inputs accept 125 Vdc inputs and are for use
with source output devices. The inputs have software-selectable response times to
provide additional input filtering.
Topology The following table shows the topology for the DDM69000 module.
