Arrangement and function of the terminals on the CU240S Control Unit
All Control Units are equipped with the same control terminals. However, depending on the
CU version, the factory set activation for certain digital inputs and interfaces differ. (see the
block diagram for CU240S/E and for CU240S-DP/CU240S-DPF/CU240S-PN/CU240S-PN-
F).
Unlike the standard Control Units, the fail-safe Control Units CU240S DP-F and CU240S
PN-F only have six digital inputs instead of nine. They are instead equipped with two fail-safe
digital inputs. Fail-safe digital inputs are redundant and each have two terminals.
