The IS200AEPAH1BHC Multiport Interface Assembly Explained

The IS200AEPAH1BHC is an AEPA-series interface board from GE's Speedtronic Mark VIe line, listed here as a multiport interface PC board and supplied together with an IS210BPPCH1AC I/O pack processor. The listing also cross-references the IS215WEPAH2BA pitch board it works alongside. AEPA is GE's abbreviation for Alternative Energy Power Assembly — the naming used for boards in the wind-turbine and alternative-energy branch of the Mark VIe platform. In that architecture the AEPA board provides the field-side interface and signal conditioning, while the BPPC processor mounted on it supplies the compute and network side of the node.

Supplying the two halves together matters, because a functioning Mark VIe node needs both: the application-specific interface board and a healthy processor to run it and carry its traffic. If you are replacing only one half, identify which half actually failed before you buy.

Before You Order: Isolating an AEPA Fault from the Processor

On an alternative-energy node, the fault almost always falls into one of two buckets — the communication/compute side or the field/interface side. Sorting them first saves an unnecessary board:

• Node will not come online. A pack that never reports usually points to the BPPC processor, its power feed, or the IONet path — the cable, switch, or network leg — rather than the interface board.
• Specific signals wrong. If the node is communicating but individual channels read incorrectly, suspect the AEPA interface board, its connectors and protective devices, or the field wiring feeding it.
• Power. Confirm the assembly is actually powered through its connector before condemning either board; a lost feed can mimic a dead processor.
• Field devices. Encoders, actuators, and sensors out in the machine fail far more often than the board and produce identical-looking alarms.

Read the processor LEDs and the diagnostic alarms in ToolboxST against GEH-6721 before pulling hardware. In a triple-redundant (TMR) layout, confirm which of <R>, <S>, or <T> is actually faulted rather than replacing all three.

How the BPPC Processor Rides on the AEPA Board

The IS210BPPCH1AC that ships with this assembly is the generic compute core; the AEPA board it mounts on is the application-specific part. Two Ethernet ports on the processor connect the pack to IONet, the Mark VIe I/O network, with the second port providing a redundant path. The BPPC is the C-generation I/O pack processor — newer than the earlier BPPB, used in systems on ControlST V04.04 or later, and it is a standard (non-safety) pack; GE's Mark VIeS safety processors instead carry an S-group suffix.

Decoding IS200AEPAH1BHC and Its Companion Part Numbers

The primary number splits into the assembly designator (IS200), the functional acronym (AEPA), a hardware group (H1), and a revision suffix (BHC). The companion parts follow the same logic: IS210BPPCH1AC is the BPPC processor, and IS215WEPAH2BA is a WEPA (Wind Energy Pitch Axis) board. Because a wind node is built from several matched boards, always record every number on the assembly. Our GE Speedtronic Part Number Decoder explains each field, and the Mark V vs Mark VI: DS200 to IS200 guide gives the wider lineage.

Details That Speed Up Your Quote

To match this multi-board assembly correctly, send us:

• Every full part number on the node — the AEPA, the IS210BPPCH1AC processor, and any WEPA board — each with its suffix.
• The revision codes on the board labels, with a photo of the labels if you can.
• Turbine model and whether the platform is Mark VI or Mark VIe.
• Quantity and how urgent the situation is.
