About the GE Mark IV/V

GE Mark IV and Mark V Speedtronic systems still control a large installed base of Frame and LM gas turbines. The hardware is legacy, so board-level failures, power-supply ageing and revision mismatches are common reasons operators need a verified spare quickly.

AGO Aviation supports Mark IV and Mark V users with part-number-led sourcing of DS3800, DS3820 and related control cards, power supplies and interface modules. We confirm the board revision, slot and system configuration before quoting.

Part families we source

  • •DS3800 and DS3820 control, I/O and communication cards
  • •Power supplies, relay modules and interface hardware
  • •Mark IV and Mark V processor and memory boards
  • •Related sensors, cables and termination components

How we verify before quoting

  • •Board number, revision and slot checked against the installed Mark IV/V rack before quotation.
  • •Configuration and firmware context reviewed where the board stores site-specific logic.
  • •Photographs and connector details requested when the original label is damaged.

Frequently asked questions

Do you supply DS3800 and DS3820 cards?

Yes. We source DS3800, DS3820 and related Mark IV/V control cards, subject to verification of the board revision, slot and system configuration.

Can you help when the board label is unreadable?

Send clear photographs of the board, connectors and any visible markings. Our team will compare them with available records and propose the most likely reference for verification.

Why is revision matching important for Mark IV/V boards?

Different revisions and configurations may not be interchangeable in a legacy rack. We confirm the installed revision and slot before quoting so the replacement matches the system.
