- Manufacturer: Beckhoff Automation
- Series / Model: CX2130 (e.g., CX2130-0000)
- Device Type: Power Supply & System Module for Embedded PC Series CX2000
The Beckhoff CX2130 power supply module is a vital core element of the CX20x0 Embedded PC system. It feeds stable DC voltages to the CPU module, powers the attached K-bus or E-bus (EtherCAT) I/O terminals, and houses integrated capacitive UPS charging circuits alongside diagnostic displays.
Due to intense 24/7 thermal duty inside control cabinets, power components, internal DC-DC converters, and filtering capacitors undergo natural degradation. Faults typically result in random TwinCAT PLC reboots, failure to power up the CPU, EtherCAT bus terminal communication drops, or total power loss.
What we repair on Beckhoff CX2130 modules:
-
Primary Switched-Mode Power Supply: Board-level repair of internal SMPS circuits, PWM controllers, switching MOSFETs, and input surge protection elements.
-
Bus Power Distribution Rails (E-bus / K-bus): Servicing of dedicated DC-DC step-down converters supplying power to downstream EtherCAT and Bus Terminals.
-
Integrated Capacitive UPS & Charging Logic: Repair of charging/discharging management circuits, voltage monitoring, and backup storage interfaces.
-
Diagnostic Display & User Interface: Repair of LC display readouts, status LED indicators, and navigation switch controls.
-
Backplane Interconnects & Connectors: Replacement of damaged multi-pin PC-104 / CX system bus connectors and repair of thermally stressed PCB traces.
Benefits of our repair service:
-
No TwinCAT License or Setup Alterations: Hardware-level repair allows you to re-integrate the original module with zero changes to TwinCAT runtime software or node addressing.
-
Cost-Effective Restoration: Servicing the power module is significantly more economical than replacing system-level Beckhoff components.
-
Proactive Capacitive Overhaul: High-stress electrolytic capacitors in power rails are replaced during the repair process to guarantee maximum system stability.
