Product Description:
The CX1100-0004 is a power supply and interface module manufactured by Beckhoff for the CX Embedded PC Systems series. Installed at the left end of a CX controller stack, it distributes field and logic power, provides local operator feedback, and forwards E-bus signals to the attached terminal block. Within industrial automation cabinets, it supports programmable logic, motion, and data-acquisition tasks by combining 24 VDC energy distribution, diagnostic LEDs, and a compact alphanumeric display in one housing.
The module accepts an input of 24 VDC (-15 %/+20 %), so typical 24 V control supplies can fluctuate without interrupting operation. Internal dissipation is limited to 3.5 W, which minimizes panel heating and allows dense mounting. Its housing is rated at IP20, and this finger-safe protection class is intended for equipment installed inside an enclosure rather than on open machinery. An integrated power feed delivers up to 2 A on the E-bus, letting several digital or analog terminals draw current directly through the backplane. A replaceable 4 A fuse protects the upstream supply; if an I/O short occurs, the fuse clears before cabinet wiring is damaged. Cage-Clamp connectors speed field wiring, while the PWR, L/A Run, and RUN LEDs report supply status, link activity, and PLC execution.
The front panel is only 40 mm wide, and the unit measures 100 mm in height and 91 mm in depth, so multiple controllers fit on a standard DIN rail. A dielectric strength of 500 Veff isolates low-voltage electronics from neighboring modules when transient potentials arise. Operators view messages on a 2-line, 16-character FSTN display, which is driven by an 8 kByte NOVRAM that retains system data during power loss. Because an E-bus connection is present, no additional coupler is needed to join the CX CPU to Beckhoff I/O slices.
