8.5 Transducer Block
Transducer Block Function
The transducer block de-couples (or insulates) function blocks from local I/O devices, such as
sensors or actuators. In the Logix 3400IQ digital positioner, the transducer block takes the position
from the analog output block and sends it, along with other parameters, to the positioner subsystem.
Transducer Block Parameters
Table 8.5 lists the FF and Valtek product-defined parameters and their default values in the transducer
block.
