System compatibility

CU211 belongs to KEBA Kemro K2 control system family,matched with KEMRO-BUS-8 backplane,I/O modules and power modules.Widely applied in injection molding,die-casting machine control cabinets.This is a discontinued legacy CPU module for equipment maintenance spare replacement.

Function

CU211 serves as KEBA rack CPU controller module.It executes user control program,completes logic operation and motion control calculation,stores machine parameters and recipe data.It has built-in watchdog circuit to avoid system crash caused by program abnormality.It communicates with all I/O and functional modules via backplane bus,collects field signal and outputs control commands.It acts as the core processing component for Kemro K2 modular control system.

Installation

Insert CU211 into the designated rack slot and lock the latch.Complete 24V power wiring according to wiring drawing.Check power polarity,backplane connection and cabinet grounding before power-on.

Interface

‑24Vdc power input terminal

‑Kemro K2 backplane gold finger connector

‑Status and fault LED indicator

‑Serial port for program upload and download

Circuit feature

Built-in ESD and surge suppression circuit,watchdog protection,non-volatile memory design,strong anti-interference performance for industrial cabinet environment.

Feature

CU211 is obsolete KEBA series spare part.Typical failures include system boot failure,program loss,communication breakdown,connector oxidation.Check module circuit,gold fingers and memory chip before replacement.This module must match Kemro K2 series rack system,direct substitution without inspection is not recommended.

Diagnostic

When program error,communication failure or internal hardware fault occurs,the module triggers protection and lights up fault LED.

Built‑in function:Program execution,logic and motion control,parameter storage,watchdog protection,backplane communication,self-diagnosis and fault alarm,used as KEBA Kemro K2 series CPU controller module spare replacement.

Product Brief

CU211 is KEBA old industrial rack CPU controller module for injection molding and die-casting machine automation equipment.Confirm compatibility with Kemro K2 backplane before ordering.ESD protection required during handling and installation.
