Product Details：

KEBA SI101 is a fieldbus communication expansion module developed for KEBA Kemro K2 control system, widely installed on ENGEL hydraulic injection molding machines and die-casting equipment. It serves as a bus coupling unit between the master CPU and external fieldbus devices, enabling reliable high-speed data exchange between the Kemro rack and peripheral automation components. It can expand the networking capability of the control rack, supporting connection with remote I/O stations and third-party bus devices for complex multi-axis injection molding and pressure closed-loop control.

This module communicates with the main controller via proprietary Kemro K-Bus backplane. It receives command data from the CPU, converts internal bus protocol signals into standard fieldbus signals, and feeds back status data from field devices such as sensors and valve regulation modules to the master controller. Built-in signal isolation circuit suppresses electromagnetic interference generated by hydraulic pumps and solenoid coils, preventing communication frame loss and abnormal data transmission. LED indicators on the front panel clearly display bus running status and error codes, helping maintenance engineers quickly locate communication faults on site.

Engineers can configure bus parameters and device mapping through KEBA engineering software. Integrated communication watchdog continuously monitors data transmission quality. When bus disconnection, frame error or undervoltage condition is detected, alarm messages will be uploaded to the HMI and trigger safety prompts to avoid unexpected mold movements. The PCB is coated with conformal coating, featuring good shock resistance and EMC immunity, suitable for dusty and oil mist workshop environment.

It adopts standard rack plug-in installation structure and matches Kemro K2-200 / K2-400 backplane rack. This KEBA SI101 module has been discontinued by the manufacturer, and it is supplied in the aftermarket as a replacement spare part for legacy ENGEL injection molding machines. Technicians can replace the faulty communication module safely after power cut without modifying the original machine control program.

It is a key networking spare part in industrial automation aftermarket, expanding the communication capacity of the whole Kemro control rack.

Key specifications：KEBA SI101 fieldbus module,24VDC power supply from K-Bus,proprietary Kemro K-Bus,rack plug-in mounting,IP20. Operating temperature range: 0°C to +55°C. It supports bus parameter configuration, signal continuity test and K-Bus communication verification during maintenance.

This SI101 fieldbus module cooperates with KEBA master CPU and I/O boards, realizing stable fieldbus networking for injection molding automation control systems.
