More Information

Overview Manuals Output Groups Load Review Acceptance Application
  • Thirty-two 24 VDC digital output points
  • Four grouped banks support dense actuator wiring
  • Individual LEDs assist commissioning and fault isolation

DO321 gives a legacy rack controller a dense bank of switched machine outputs.

Grouped field power means a supply or common problem can affect multiple channels and should be checked before changing the card.

The execution recorded in Revision remains the controlling reference for sourcing and replacement decisions.

Availability, condition, price, and shipping time for DO321 are confirmed during quotation.

Description
DO321 provides thirty-two discrete output points for high-density machine actuator control.

The board receives command data from the rack controller and distributes 24 VDC switching signals to grouped field loads with individual state indication.

Replacement work should retain the documented execution, rack slot, field-power grouping, connector pinout and the current demand of every connected coil or relay.

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.
What load information is needed before ordering KEBA DO321?
List the voltage, steady and inrush current, load type and channel grouping for all connected coils, lamps, relays and valves.
Can KEBA DO321 be selected from the base number alone?
Use the base model for the product record, then match the complete installed label because its execution can define board and connector compatibility.
Why can several KEBA DO321 outputs fail together?
A shared group supply, common return, connector seating issue or upstream fuse can remove an entire group even when individual commands are present.
How should KEBA DO321 be tested after replacement?
With motion inhibited, command each output separately, compare its LED with field voltage and load response, and then test interlocks under supervised operation.
What precautions apply when KEBA DO321 drives solenoids?
Confirm coil current and suppression, avoid disconnecting energized inductive loads and check that the field supply can handle simultaneous inrush.
Does KEBA DO321 require an external communication cable?
No separate fieldbus cable terminates on the output card; commands arrive through the host rack backplane.
Which evidence best prevents a wrong KEBA DO321 replacement?
Provide the complete installed label, front and rear images, connector and terminal photographs, rack position and the machine electrical drawing.
