Product Details：

KEBA CP-251/U is the CP251 main control CPU module belonging to KEBA KePlast i2000 control family, widely used as the core controller for injection molding machines and hydraulic servo automation equipment. It undertakes PLC logic execution, closed-loop motion synchronization, process recipe management and safety monitoring for the whole machine.

This module receives real-time feedback signals from displacement transducers, pressure sensors, proximity switches and safety interlock contacts. It runs the molding cycle program and outputs control commands to proportional hydraulic valves and servo drives to realize clamping, injection, holding pressure, plasticizing and ejection actions with high repetitive precision. It supports multi-loop synchronous control for complex hydraulic processes.

It is equipped with Ethernet and serial communication ports. It connects with KEBA operator panels, I/O terminal modules and upper HMI systems for data exchange. Operators can modify molding recipes, view cycle statistics and check fault logs on HMI. Internal non-volatile memory keeps machine parameters and product recipes stable after power off.

It carries comprehensive hardware self-diagnosis and safety monitoring functions. It continuously checks bus communication status, signal loop integrity and internal temperature. When faults such as communication timeout, sensor signal loss or over-temperature are detected, it triggers alarm and safe stop output to protect molds and mechanical structures.

It adopts plug-in rack mounting and matches standard Kemro I/O backplane. The circuit board is coated with conformal coating, with good vibration resistance and EMC performance, adapting to dusty and high-noise plastic workshops. It supports program backup and restore, which simplifies commissioning and spare parts replacement during equipment overhaul.

It is the core control hardware for many European brand injection molding machines equipped with KEBA KePlast systems. It is commonly used for original equipment matching, old control cabinet renovation and spare parts replacement. It is a stable real-time control solution for hydraulic and servo molding equipment.

Key specifications：KEBA CP-251/U CP251 main CPU module,24VDC rated supply,Ethernet and serial interface,rack plug-in installation. Operating temperature range: 0°C to +55°C. It supports program upload/download, recipe backup, bus communication and I/O signal simulation test during maintenance.

This CP251 CPU module cooperates with KEBA I/O modules, sensors and drive units to form a complete KePlast automation control system. It guarantees stable and repeatable production cycles for injection molding machinery.
