Application
Simplex Configuration
Isolated 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.
