For the number of digital inputs and outputs
of REF 54_ feeder terminals, refer to the
tables above. The number of matching trans-
formers, sensor inputs and analogue inputs
and outputs, and the auxiliary voltage range
vary between the different hardware versions
of REF54_. Each hardware version of REF
541 and REF 543 can be supplied with an
RTD/analogue module.

Software configuration

Each REF 54_ feeder terminal allows various
software configurations based on separate
functions. Functions included in the selected
functionality level can be activated within the
scope of the I/O connections and considering
the total CPU load of the functions.
