Product Description:
The CX1100-0004-1001 is a power supply and interface module produced by Beckhoff for the CX Embedded PC Systems series. It attaches directly to a CX CPU segment to furnish operating voltage, local display functions, and fieldbus links needed by the control assembly. In an automation cabinet, this unit distributes low-voltage power, presents status text, and offers wiring points so machine builders can consolidate control hardware on a DIN rail without external PCs. Its design supports compact PLC architectures where space, wiring simplicity, and integrated visualization are priorities.
Electrical input is a 24 VDC source, protected by a customer-side 4 A fuse that matches the module’s internal limit. Under load, the device draws no more than 3.5 W, so cabinet thermal planning remains straightforward. Insulation paths tolerate 500 Veff dielectric strength between supply and logic, reducing risk during field wiring. Cabinet space is conserved with a 40 mm housing width and a mounting height of 100 mm; depth measures 91 mm. Cage-Clamp spring terminals accept solid or stranded conductors, and the internal power rail feeds the E-bus backplane while dedicated capacitors buffer brief outages to protect the 8 kByte NOVRAM that stores retentive process data. Because no I/O DPRAM is fitted, the host CPU communicates across the serial backplane without shared-memory overhead.
For panel rating purposes, the housing carries IP 20 protection, permitting installation inside enclosures where dust and finger-contact barriers are external to the module. Operators read operating codes on an alphanumeric screen that combines a 2 × 16 character format with an FSTN display, eliminating the need for a separate service terminal. The internal bus supplies 2 A to chained E-bus terminals, and the E-bus connection enables automatic topology enumeration by the control software. Spring-loaded terminals remain accessible even when adjacent CX modules are attached, maintaining consistent wiring tension over temperature cycles.
