For the number of digital inputs and outputs of REF 54_ feeder terminals, refer to
section "Order number" above. The number of matching transformers, sensor inputs
and analogue inputs and outputs, and the auxiliary voltage range vary between the
different hardware versions of REF 54_. Moreover, REF 541 and REF 543 can be
supplied with an RTD/analogue module. For more detailed information about the
hardware of REF 54_, refer to section "Hardware versions" on page 9.

Each REF 54_ feeder terminal allows different software configurations based on
separate functions (refer to section "Functions of the feeder terminal" on page 17).
Functions included in the selected functionality level (refer to section "Ordering
Information" on page 88) can be activated within the scope of the I/O connections
and considering the total CPU load of the functions.
