Transducer Block

The transducer block accepts a signal from an output block as a set point to position a valve using a pneumatic
actuator. Input to the transducer block is in percent. Closed is 0%, and open is 100%. The transducer block contains
setup and calibration information and can be tuned to closely match the actuator. Input characterization permits
modifying the overall characteristic of the instrument‐actuator‐valve combination in order to modify the installed gain
characteristic of the loop. The transducer block can also be used to perform instrument and valve diagnostics and
trigger performance alerts.
Parameter List
D Read/Write Capability: RO - Read Only, RW - Read Write
D Mode: The block mode(s) required to write to the parameter
D Protection Category: Indicates whether or not the parameter is writable while the PROTECTION parameter
is set to a particular level.
-N/A indicates a read‐only parameter that is never writable, regardless of the value of the PROTECTION parameter
-NONE indicates a read‐only parameter that is always writable, regardless of the value of the PROTECTION parameter
-CAL indicates a parameter that is only writable while the value of the PROTECTION parameter is "NONE".
-SETUP indicates a parameter that is only writable while the value of the PROTECTION parameter is "NONE" or "CAL".
-ALL indicates a parameter that is writable while the value of the PROTECTION parameter is "NONE", "CAL", or "SETUP & CAL".
D Double indentation and shared Index Number indicates sub‐parameter
