Product Description:
Beckhoff manufactures the CX1100-0930-1001 as part of its CX Embedded PC Systems series. The unit combines a 24 V buffer power supply with control electronics that interface directly with the base CPU, allowing the automation PC to survive short mains interruptions without data loss. In an installation, the module mounts next to the CPU slice, filters the incoming DC, keeps diagnostic status visible on the front panel, and releases a power-fail signal that triggers an orderly system shutdown. The assembly provides supply conditioning and short-term energy storage for discrete and process automation cells.
The module accepts a nominal input of 24 V DC and charges its internal capacitor bank with up to 4 A; this charging phase is limited by onboard electronics to protect upstream supplies. When backup is required, the device can feed the CX bus with a continuous 2.0 A output, maintaining logic and field interfaces. Thermal stress stays low because maximum power loss is only 2 W, even at full load. The output channel is short-circuit and overload protected, disconnecting the load instantaneously and eliminating the need for external fusing.
Housed in a compact 95 x 100 x 91 mm enclosure, the CX1100-0930-1001 carries an IP20 protection rating, so it is intended for installation inside a closed control panel. The energy reservoir provides 40 As of charge through capacitive storage technology, yielding several seconds of retention time that can be adjusted with a rotary switch or by software. The module links to the CPU over a 16-bit ISA (PC/104) interface and issues a digital power-fail output when the input decays. Three diagnostic LEDs report the 24 V input, 24 V output, and charge states, while a 5-pin pluggable connector brings in the supply voltage.
