For Q-Line system applications, Westinghouse 2840A21G03 provides the function of a QAO Card.
Within the control architecture, this product serves the equipment role stated in its description and should be selected by exact model identity rather than by appearance or a broadly similar name. Its role should remain distinct from that of similarly named assemblies.
For system maintenance, this product is associated with the Q-Line family and the circuit breakers category. Configuration and compatibility should be confirmed for the exact system in which it will be used. The plant's maintenance records should support final product selection.
In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. This helps preserve the function assigned to the installed control node.
DCS Center can repair your 2840A21G03 part or offer an exchange for quick turnaround. This Westinghouse Q-Line unit New, Remanufactured or Repaired is fully warranted by DCS Center.
