Product Details：

KEBA CU312 is an upgraded high-performance master CPU module under KEBA Kemro K2 and KePlast series, widely equipped on mid-to-high end ENGEL injection molding machines and die-casting automation equipment. Compared with CU211, this model adopts higher-speed processing core, larger memory capacity and faster backplane bus cycle, suitable for thin-wall injection, multi-cavity mold and all-electric injection molding processes that require high real-time performance. It undertakes the core calculation work of the whole control rack, including sequence logic execution, multi-axis interpolation motion, hydraulic pressure closed-loop regulation, safety chain judgment and bus communication management.

This module connects to all plug-in functional boards through the proprietary Kemro K-Bus backplane. It receives real-time feedback signals from pressure sensors, displacement transducers and safety limit switches, dynamically calculates the deviation between setting value and actual feedback, and sends command signals to hydraulic regulation modules, digital output boards and communication adapters to complete the coordinated actions of mold clamping, injection, holding pressure, plasticizing and ejection. It supports local storage of a large number of mold recipes, and cooperates with dedicated memory card adapter modules to realize quick import and export of offline parameter files.

It carries rich communication expansion interfaces, supporting Ethernet, CAN bus, USB and serial ports to connect operator panels, distributed I/O stations and upper MES production management systems. Engineers can download control programs, configure module mapping, adjust closed-loop PID parameters and view historical fault logs via KEBA engineering software. Built-in multi-channel watchdog and power temperature monitoring circuit continuously verify backplane data frame and internal device state. When communication timeout, undervoltage, over-temperature or signal error is detected, it will trigger safety stop and alarm output to protect molds and mechanical structures. The circuit board adopts conformal coating treatment, with good vibration resistance and EMC performance, adapting to dusty and oil mist plastic workshop environment.

It adopts standard plug-in rack installation structure, matched with Kemro K2-200 / K2-400 backplane rack. This model has been discontinued by KEBA factory, and it is mainly circulated as maintenance spare part for legacy ENGEL injection molding machines. Technicians can replace the faulty CPU board independently after safe power-off without modifying the original wiring of the machine.

It is a high-value core spare part in plastic machinery maintenance market, which determines the response speed and stable precision of the whole injection molding control system.

Key specifications：KEBA CU312 master CPU module,24VDC power supply from backplane bus,high-speed K-Bus interface,rack plug-in mounting,IP20. Operating temperature range: 0°C to +55°C. It supports program upload/download, recipe backup and restore, bus scanning test and hardware compatibility verification during maintenance.

This CU312 main CPU cooperates with KEBA I/O, temperature and hydraulic regulation modules to build a high-precision injection molding closed-loop automation control system, meeting the demanding process requirements of complex molding products.
