System compatibility

DO272/A belongs to KEBA Kemro K2 control system family,matched with KEMRO-BUS-8 backplane,CPU modules and power modules.Widely applied in injection molding,die-casting machine control cabinets.This is a discontinued legacy digital output module for equipment maintenance spare replacement.

Function

DO272/A serves as KEBA rack 14-channel digital output module.It receives control commands from main CPU and outputs 24Vdc switching signals to drive field solenoid valves and actuators.The 14 outputs are divided into two groups,each channel supports short-circuit detection and overcurrent protection,able to cut off faulty channel independently.It adopts galvanic isolation design to protect the backplane circuit from field surge interference.It feeds channel operating status and fault information back to the main controller via backplane bus.It acts as high-density field digital output driving component for Kemro K2 modular control system.

Installation

Insert DO272/A into the designated rack slot and lock the latch.Complete field output wiring according to wiring drawing.Check 24V power polarity and cabinet grounding before power-on.

Interface

‑24Vdc power input terminal

‑Field digital output terminal block

‑Kemro K2 backplane gold finger connector

‑Channel status and fault LED indicator

Circuit feature

Built-in ESD and surge suppression circuit,galvanic isolation design,independent channel protection,strong anti-interference performance for industrial cabinet environment.

Feature

DO272/A is obsolete KEBA series spare part.Typical failures include single channel no output,channel burnout,short-circuit protection trip,connector oxidation.Check module circuit,output channels and gold fingers before replacement.This module must match Kemro K2 series rack system,direct substitution without inspection is not recommended.

Diagnostic

When channel short-circuit,overcurrent or internal hardware fault occurs,the module triggers protection and lights up fault LED.

Built‑in function:14-channel digital signal output,field actuator driving,per-channel short-circuit detection,overcurrent protection,status monitoring,self-diagnosis and fault alarm,used as KEBA Kemro K2 series digital output module spare replacement.

Product Brief

DO272/A is KEBA old industrial rack high density 14-channel digital output 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.
