Application
Simplex Configuration
Digital output modules provide a suitable interface to non-
critical output devices. These non-critical devices typically
include status alarms or other field devices that are not used
for primary safety shutdown purposes. Although much of the
circuitry on the digital output module is automatically tested,
some logic circuits and the field-side output switch are simplex
and non-tested. This simplex configuration is illustrated in
Figure 3. For safety-critical outputs requiring fail-safe or
fault tolerant output configurations, Guarded digital output
modules should be used.
