6.8 Defining Analog Output Channel Blocks
Overview
The Analog Output channel block represents a single analog output point on the
ANALOG OUTPUT WITH HART Modules. The Analog Output channel block converts
the output value (OP) to a 4-20 mA output signal for operating final control elements
such as valves and actuators in the field. The OP parameter value can be controlled from
a Experion regulatory point, the operator, or an SCM.
To convert the OP value to a 4-20 mA signal, the Analog Output channel performs the
following:
Direct/Reverse Output Function
Nonlinear Output Characterization
The following is a functional diagram of the analog output channel block.
