System compatibility

SM250/A belongs to KEBA Kemro K2 control system family,matched with KEMRO-BUS-8 backplane,CPU modules and SSI absolute encoders.Widely applied in injection molding,die-casting machine control cabinets.This is a discontinued legacy SSI encoder interface module for equipment maintenance spare replacement.

Function

SM250/A serves as KEBA rack 4-channel SSI interface module.It connects up to 4 sets of SSI absolute position encoders,collects high-resolution position feedback data and transmits position values to main CPU via backplane bus.It has built-in sensor failure detection function to monitor encoder cable breakage and signal loss.It supports configurable SSI frame format and clock rate.It adopts signal isolation to resist field electromagnetic interference.It acts as high-precision position feedback acquisition component for Kemro K2 modular control system.

Installation

Insert SM250/A into the designated rack slot and lock the latch.Complete SSI encoder cable wiring according to wiring drawing.Check 24V power polarity and cabinet grounding before power-on.

Interface

‑24Vdc power input terminal

‑4 groups SSI encoder signal port

‑Kemro K2 backplane gold finger connector

‑Channel status and fault LED indicator

Circuit feature

Built-in ESD and surge suppression circuit,differential SSI signal transmission,signal isolation design,strong anti-interference performance for industrial cabinet environment.

Feature

SM250/A is obsolete KEBA series spare part.Typical failures include position reading jumping,signal loss,encoder communication failure,connector oxidation.Check module circuit,SSI signal channels and gold fingers before replacement.This module must match Kemro K2 series rack system,direct substitution without inspection is not recommended.

Diagnostic

When encoder cable break,signal attenuation or internal hardware fault occurs,the module triggers protection and lights up fault LED.

Built‑in function:4-channel SSI encoder signal acquisition,absolute position reading,sensor fault detection,status monitoring,self-diagnosis and fault alarm,used as KEBA Kemro K2 series SSI interface module spare replacement.

Product Brief

SM250/A is KEBA old industrial rack 4-channel SSI encoder interface 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.
