BECKHOFF CX2100-0904 Power Supply Unit with Integrated Capacitive UPS, CX2000 Series

Overview The BECKHOFF CX2100-0904 is a power supply module with built-in capacitive UPS for Beckhoff CX2000 series embedded PCs (CX2033). It supplies stable 24V DC power to the CPU, expansion modules and E-bus/K-bus I/O terminals, widely stocked as spare for industrial automation, machine control and intelligent building control systems.

Features This CX2100-0904 module adopts passive fanless cooling, supporting wide temperature operation from -25℃ to +50℃. The CX2100-0904 comes with a 2×16 character FSTN backlit LCD screen, selector switch and enter key for local status check and parameter browsing. The integrated capacitive UPS (75As) enables automatic data saving and orderly system shutdown when mains power fails. It is controlled via TwinCAT, with diagnostic LEDs for power and bus status.

Specs Model: CX2100-0904 Series: Beckhoff CX2100 Type: Power supply module with capacitive UPS Input voltage: 24VDC (-15%/+20%) Output power: 45W E‑bus/K‑bus: 5V DC / 2A UPS capacity: 75As Display: 2×16 FSTN LCD Mounting: DIN rail Protection class: IP20 Certifications: CE Product status: Active industrial automation spare

Principle The module converts the input 24V DC and distributes power to the CX embedded controller and I/O bus. When power loss occurs, the built-in capacitor provides backup power to complete safe shutdown and data storage, avoiding data corruption. It communicates status information to the TwinCAT runtime for monitoring.

Applications The CX2100-0904 is widely deployed in packaging machines, conveyor systems, HVAC control panels and general factory automation cabinets. It serves as power and UPS backup unit for CX2033 embedded PLC controllers.
