IS200AEADH3ADA: The Input Terminal Board Side of the AEAD Family

Terminal boards are where a control system physically meets the plant — the landing point for the wiring that runs out to sensors and equipment. The IS200AEADH3ADA is the H3A configuration of GE's AEAD family at revision DA, and it is the variant that surplus catalogs consistently list as an Input Terminal Board. The AEAD acronym itself belongs to the Mark VIe wind era of GE's IS200 hardware: the same family's H1A group is cataloged as the Input/Output Grid Fork module for wind turbine and balance-of-plant control, while the H3A and H4A groups carry the terminal board role. Because everything with an IS200 prefix tends to get shelved under Mark VI — as this listing's title does — treat the full part number, not the shelf label, as the source of truth.

We will be straight with you: GE's own documentation for this board shipped with the original equipment and is scarce on the open web, so this page sticks to what is verifiable — the family, the function class, the numbering, and how to buy it without guessing.

Field Wiring First: What to Rule Out Before Swapping a Terminal Board

Input terminal boards get blamed for a lot of faults they did not commit, because every field problem passes through them. Before ordering, spend an hour proving where the fault actually lives:

• Terminations. A loose screw, a cold-flowed lug, or corrosion at the landing point produces the same open circuit as a failed board trace. Retorque and inspect the suspect points — in wind-site cabinets, vibration works terminations loose over years.
• The signal itself. Lift the wire and measure the sensor or contact at the terminal. If the signal is absent at the landing point, the problem is out in the field, and a new terminal board will change nothing.
• The mating connection. Terminal boards hand their signals onward through connectors and cables to the processing electronics. A half-seated connector or damaged cable mimics a board failure precisely; reseat before you replace.
• The electronics downstream. If the signal is good at the terminal and the connection is sound, the fault may sit in the module that reads this board — not the terminal board itself. Swap-testing there first is cheaper than guessing.

When the terminal board is genuinely at fault — burned channel, damaged trace, failed onboard component — replacement beats repair, especially on conformally coated hardware.

Why the H3A Group Designation Matters

Within the AEAD family, the H-group is the difference between distinct physical boards: H1A is the grid fork I/O module; H3A and H4A are the input terminal board configurations. They share four letters and nothing you can interchange. Order the group your cabinet actually holds — IS200AEADH3A here — and match the DA revision against your installed unit or site records. The general decoding pattern (IS200 + function code + H-group + revision) is laid out in our GE Speedtronic Part Number Decoder.

New Surplus, Factory Packaged: What NSFP Buys You

This unit is NSFP — new surplus in its factory packaging, never fielded. For a terminal board, that means unworn terminations and no history of overtightened screws, lifted pads, or previous repair work, which is exactly what you want at the point where every field wire lands. Condition and warranty for this specific unit are stated in the table at the bottom of this page.

Building a Complete Quote Request

Five things let us confirm the match and quote in one pass:

• The full number with revision — IS200AEADH3ADA
• A photo of the label on your installed board
• The system it serves (wind turbine or balance-of-plant equipment) and the control generation per your documentation
• Quantity — and whether a shelf spare should ride along
• Urgency: forced outage or planned work
