Simplex Configuration
A single RTD input module and multiplexer provide a
suitable interface to non-critical input signals. Although
many of the circuits in the RTD input module and multiplexer
are automatically tested and annunciated, some logic circuits
and field-side sensing circuits are simplex and non-tested.
This simplex input configuration is illustrated in Figure 5.
