Product Details：

KEBA DO272A is a 14-channel galvanically isolated digital output expansion module of KEBA KeConnect and Kemro K2 series, widely used on ENGEL hydraulic injection molding machines and die-casting automation equipment. It is the commonly written shorthand version of DO272/A, used to convert control commands from the master CPU into stable switching signals for on-site actuators, including hydraulic solenoid valves, contactors, solid state relays and indicator lights. It is ideal for injection molding machines that require abundant output points for multi heating zones and multiple hydraulic axes.

This module communicates with the main controller via proprietary Kemro K-Bus backplane. It receives logic instructions for clamping, injection, holding pressure, plasticizing, ejection and lubrication sequences. Each channel is rated 2A at 50% simultaneity and equipped with fast shutdown circuit specially optimized for inductive coil loads, which absorbs reverse electromotive force generated by solenoid valves and extends actuator service life. The 14 output channels are divided into independent groups with separate protection. If short-circuit or overload happens on one channel, only the corresponding group will cut off output, while other channels keep working normally.

Orange LED status indicators are arranged on the front panel for each channel, allowing maintenance engineers to read output status and locate faults quickly on site. Engineers can configure signal mapping and parameter assignment through KEBA engineering software. Built-in continuous channel diagnosis and bus watchdog circuit monitor data integrity constantly. When communication interruption, overcurrent or hardware abnormality is detected, alarm information will be uploaded to the HMI to prevent unexpected mold movement. The PCB adopts conformal coating treatment, with good shock resistance and EMC immunity, adapting to dusty and oil mist workshop environment.

It adopts standard rack plug-in structure and matches Kemro K2-200 / K2-400 backplane system. This DO272A is an e

nd-of-life spare part from KEBA factory, and it is supplied in the aftermarket as a high-point-count replacement spare part for legacy ENGEL injection molding machines. Technicians can replace the faulty module safely after power cut without modifying the original field wiring and control program.

It is a popular high-density I/O spare part in industrial automation aftermarket, supporting rich actuator drive points for complex injection molding sequential control chains.

Key specifications：KEBA DO272A digital output module,14 channels,24VDC,2A per channel at 50% simultaneity,galvanic isolation,fast shutdown for inductive loads,rack plug-in mounting,IP20.
