Product overview
2.2 CX2100­0904 / CX2100­0914 product overview
The purpose of the CX2100 Power Supply and UPS modules is to supply power to the components of a
CX20x0 system (CPU modules, system and extension modules). The power supply units are controlled via
TwinCAT. an FSTN LCD display with 2 x 16 characters and a selector switch as well as an enter key allow
the querying of internal status values as well as self­created display parameters or menus with and without
input options. K­bus or alternatively EtherCAT Terminals can be connected to the power supply unit on the
right­hand side. The respective bus system is detected automatically and operated by the CPU. Power is
supplied to the E­bus or K­bus electronics in the I/O terminals by an integrated but internally separate 2 A/5
V power supply unit. The CX2100­0904 Power Supply Unit is passively cooled and is intended for operation
in the extended temperature range of ­25 to +50 °C. With the CX2100­0904 UPS Power Supply Unit the
system can store data on the storage medium in case of a power failure and subsequently shut down
properly. The CX2100­0914 power supply unit must be used if a longer holding time is required or if a UPS is
required for a CX2040 system. The charge is stored in a CX2900­0192 battery module.
