System compatibility

BL250/B belongs to KEBA Kemro K2 control system family,matched with KEMRO-BUS-8 backplane,CPU modules and distributed I/O modules.Widely applied in injection molding,die-casting machine control cabinets.This is a discontinued legacy bus coupler module for equipment maintenance spare replacement.

Function

BL250/B serves as KEBA rack bus coupler module.It acts as bus link for Kemro K2 remote I/O cluster,realizes signal conversion between internal K-bus and external fieldbus.It connects distributed remote I/O groups to main CPU controller,supports adjustable bus baud rate.It monitors real-time bus communication status and feeds back fault information to the main controller via backplane bus.It acts as remote bus coupling component for Kemro K2 modular control system.

Installation

Insert BL250/B into the designated rack slot and lock the latch.Complete fieldbus wiring and set terminal resistor according to wiring drawing.Check bus termination,24V power polarity and cabinet grounding before power-on.

Interface

‑24Vdc power input terminal

‑Fieldbus connector

‑Kemro K2 backplane gold finger connector

‑Communication status and fault LED indicator

Circuit feature

Built-in ESD and surge suppression circuit,bus signal conditioning design,strong anti-interference performance for industrial cabinet environment.

Feature

BL250/B is obsolete KEBA series spare part.Typical failures include communication disconnection,bus signal failure,LED no light,connector oxidation.Check module circuit,gold fingers and bus port before replacement.This module must match Kemro K2 series rack system,direct substitution without inspection is not recommended.

Diagnostic

When bus short-circuit,communication timeout or internal hardware fault occurs,the module triggers protection and lights up fault LED.

Built‑in function:Fieldbus coupling,K-bus and fieldbus signal conversion,remote I/O cluster connection,communication status monitoring,self-diagnosis and fault alarm,used as KEBA Kemro K2 series bus coupler module spare replacement.

Product Brief

BL250/B is KEBA old industrial rack bus coupler 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.
