More Information

Overview Manuals Load Control Protection Installation Application
  • Fourteen 24 VDC digital outputs
  • 2 A point capacity at 50% simultaneity
  • Short-circuit protection and inductive-load diagnostics

DO272 controls a concentrated group of valves, relays and other DC loads from one KeConnect station.

Its diagnostic and protection functions reduce the time needed to separate wiring faults from controller faults.

The documented execution in Revision defines the current, protection and mechanical values used for this base-model page.

Availability, condition, price, and shipping time for DO272 are confirmed during quotation.

  • One-millisecond processing time
  • Permanent short-circuit protection
  • Fault detection reports channel problems
  • Fast shutdown limits inductive switching stress
  • Separate front 24 VDC field supply
  • K-bus carries logic power and data

  • Protected machine-output stations
Description
DO272 switches fourteen 24 VDC machine loads from a compact KeConnect output station.

Each channel is permanently short-circuit protected, and the module reports output faults while providing fast shutdown behavior for inductive devices.

A controlled replacement should preserve the documented execution, field-power grouping, K-bus address, load current and the suppression arrangement used by valves, contactors or relays.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can KEBA DO272 drive solenoid valves directly?
Yes, when voltage, steady current, inrush and inductive energy stay within the documented limits and the field supply and protective design are correct.
Why can a KEBA DO272 output show a short-circuit fault after replacement?
Check the load cable, common return, coil condition, field-supply polarity and connector alignment before assuming the replacement channel is defective.
Does the 2 A rating of KEBA DO272 apply to every point continuously?
The 2 A point value is specified at 50% simultaneity, so the complete load pattern and cabinet temperature must be considered rather than multiplying 2 A by fourteen.
What must be recorded before removing KEBA DO272?
Record the K-bus address, each output assignment, field-power terminals, load current, suppression components and any forced-output or diagnostic state.
How should KEBA DO272 outputs be tested safely?
Keep the machine inhibited, command one output at a time, confirm the LED and load response, and monitor current and diagnostics before restoring sequence control.
Can KEBA DO272 switch a high-energy inductive load without extra design review?
No. Compare stored energy and switching frequency with the 1 J at 0.2 Hz limit and add appropriate external suppression where the load requires it.
What panel space is required for KEBA DO272?
Allow 120 mm height, 100 mm depth and 32.5 mm overall width including the K-bus plug, plus access for front power and output terminals.
