Rosemount 848L
DISCRETE INPUT
BLOCK
The DI takes the manufacturer’s discrete input data, selected by channel
number, and makes it available to other function blocks as its output. The
output will have a value of either true or false along with the status of the
output. A custom feature of the DI block in the 848L is the ability to pack 8
status bits into the single output of a DI block. This is accomplished by
selecting the appropriate channel number for packed data. This feature is
used in custom applications implemented in control systems such as DeltaV.
The DI block supports a function to invert the input and alarming.
