Description

Providing short-term backup power for orderly system shutdowns, the Beckhoff CX1100-0920 is an integrated capacitive UPS module engineered for direct system bus integration with CX series Embedded PCs. Operating via a 16-bit ISA PC/104 standard system interface, this hardware module prevents critical data loss during sudden mains failure by supplying buffered energy directly to the host CPU. By utilizing durable ultra-capacitors instead of electrochemical battery chemistry, the unit delivers maintenance-free operation and high thermal tolerance in demanding industrial environments.

Features

Capacitive Storage Technology: Maintenance-free energy storage using gold-capacitors, eliminating chemical wear and battery aging.
Integrated PC/104 Interface: Seamless 16-bit ISA data and power connection directly to the embedded controller stack.
Adjustable Retention Time: Load-dependent backup windows configurable through system software control to match specific CPU shutdown cycles.
Visual Diagnostic Array: On-board LEDs providing real-time status indication for 24 V DC input, 24 V DC output, and charging status.

Applications

Persistent Data Saving: Ensuring TwinCAT persistent variable registries are fully written to non-volatile flash memory during power dropouts.
Orderly Machine Stop: Driving critical low-current control circuits to bring active machinery to a safe physical state before complete CPU power-down.
Unstable Power Grids: Buffering micro-interruptions and voltage sags in industrial processing plants without system reboots.

Empirical Engineering Insights

Alternative Models & Compatibility

The CX1100-0920 is purpose-built to align within Beckhoff CX1010, CX1020, and CX1030 Embedded PC hardware configurations. It is not compatible with newer CX2000 multi-core series architectures, which utilize differing bus layouts and power supply coupling mechanisms. Always verify your existing CPU connection header pins match the PC/104 16-bit physical bus spacing before locking the stack modules together.

Application Pitfalls & Engineering Notes

Capacitive storage units like the CX1100-0920 have a linear voltage discharge curve compared to chemical batteries. With a capacity of 40 As, the actual retention backup time is highly load-dependent. When running a maximum system load of 1.1 A, power is held for approximately 36 seconds. Systems must be configured within the TwinCAT software interface to trigger the write-to-disk persistent cycle immediately upon mains failure detection. Running external, non-CPU bus powered peripherals directly from the same 24 V DC line during an outage can rapidly deplete capacitive reserves before write sequences complete.

Commissioning & Wiring Tips

During initial commissioning, the module requires up to 4.0 A of charging current to energize the internal ultra-capacitor cells from a discharged state. Ensure the system primary power supply is sized with sufficient overhead to handle this transient inrush alongside standard operational load profiles. Check that the on-board LED diagnostics show a steady "Charge" light indicating complete capacitive cell charge before activating persistent file writes in the control logic.

Installation Guidelines

CRITICAL WARNING: De-energize all primary and auxiliary power sources before handling the module stack. Capacitive components inside this module can retain electrical potential even after mains power is disconnected. Verify voltage potential is fully discharged before joining or separating system bus modules to prevent physical ESD destruction of internal ISA interface electronics.

1 Align Module Contacts:

Inspect the PC/104 interface connectors on the side of the CX Embedded PC and the module. Carefully slide the module onto the system's mounting rail, guiding the male pins straight into the matching female sockets.

2 Secure the Rail Lock:

Engage the mechanical rail retention latch on the bottom of the module enclosure to prevent shifting or contact loss from system vibration.

3 Establish Grounding and Power:

Connect the power supply wiring to the 24 V DC terminals using high-quality shielded cabling. Ensure the DIN-rail connection is properly bonded to functional ground (FE) for transient noise rejection.

#Beckhoff CX Series #UPS Modules

What is the key advantage of the capacitive storage used in the CX1100-0920 over traditional batteries?

The CX1100-0920 utilizes ultra-capacitors instead of batteries. This means there is no chemical degradation over time, no regular replacement cycle required, and much higher thermal stability within industrial control panels.

Does the CX1100-0920 require external software configuration?

Yes. While the physical power backup occurs automatically at the hardware layer, write-to-disk behavior and safe shutdown scripts must be configured in TwinCAT to ensure persistent variables are correctly saved before energy reserves deplete.

How long will the module backup the CPU during an outage?

The backup time is load-dependent. The maximum capacity is 40 Ampere-seconds. At the maximum supported output current of 1.1 A, it provides up to approximately 36 seconds of operational retention time.

Is the CX1100-0920 compatible with CX2000 series controllers?

No. The CX1100-0920 is mechanically and electrically compatible only with Beckhoff CX1010, CX1020, and CX1030 embedded CPU series which use the legacy PC/104 16-bit ISA bus system.
