Product Details：

KEBA CU313/C is a high-end revised master CPU module of KEBA Kemro K2 and KePlast platform, widely installed on premium ENGEL hydraulic injection molding machines, die casting equipment and precision multi-cavity plastic molding machines. It is upgraded based on CU312 with expanded memory and optimized bus timing, and it works perfectly with IC101 memory card unit for fast recipe management. As the core arithmetic unit of the modular control rack, it takes charge of PLC sequence execution, multi-axis interpolation motion, hydraulic proportional valve closed-loop adjustment, safety chain monitoring and whole bus communication scheduling.

This main controller communicates with all rack-mounted functional boards including I/O modules, thermocouple temperature boards and hydraulic regulation cards via proprietary Kemro K-Bus backplane. It collects real-time feedback signals from pressure sensors, displacement transducers and safety limit switches, calculates the deviation between preset value and actual feedback, and sends high-speed command signals to each slave module to coordinate mold clamping, injection, holding pressure, plasticizing and ejection movements. It supports stable offline recipe import and export together with IC101 card reader, which helps technicians unify mold parameters and shorten debugging time during frequent mold change.

It is equipped with multiple communication interfaces such as Ethernet, CAN bus and serial port to connect local operator panels, remote I/O stations and upper MES production management systems. Engineers can download control programs, assign module addresses, tune PID closed-loop parameters and check historical fault records through KEBA engineering software. Built-in multi-channel watchdog, power supply and temperature monitoring circuit keeps checking data frame integrity and chip working status. If communication interruption, overload or hardware abnormality occurs, it will trigger safety stop and alarm signal to protect expensive molds and mechanical structures. The PCB circuit adopts conformal coating treatment, featuring good shock resistance and EMC immunity, suitable for dusty and oil mist environment inside plastic workshops.

It adopts standard slot plug-in structure and matches Kemro K2-400 backplane rack. This CU313/C version is end-of-life from KEBA, and it is circulating in the aftermarket as a high-value spare part for legacy high-end ENGEL injection machines. Maintenance staff can replace the faulty CPU board directly after power cut without modifying the original machine wiring.

It is a sought-after core spare part in industrial automation spare parts market, determining the response speed and steady precision of the whole injection molding control system.

Key specifications：KEBA CU313/C master CPU module,24VDC power supplied from backplane bus,proprietary high-speed K-Bus interface,rack plug-in mounting,IP20. Operating temperature range: 0°C to +55°C. It supports program upload and download, recipe backup and restore, bus scan test and hardware compatibility verification during maintenance.

This CU313/C main CPU cooperates with KEBA I/O, temperature and hydraulic regulation modules to build a complete high-precision injection molding closed-loop control system, meeting strict stability requirements for thin-wall and multi-cavity molding production.
