GE IS215WETAH1BB / IS200WETAH1AGC – WETA I/O Terminal Board for Mark VI/VIe and EX2100 Systems

The IS215WETAH1BB and IS200WETAH1AGC are part of GE’s WETA series, used widely in Mark VI/Mark VIe turbine controls and EX2100 excitation cabinets. In practical terms, this board serves as a robust I/O interface and signal conditioning layer—bringing field wiring into the control system in a clean, maintainable way. One thing I appreciate is how the WETA typically keeps signal integrity solid under electrical noise, which is common around generators and turbine auxiliaries.

From my experience, the “IS215” variant is a later hardware generation that aligns well with Mark VIe panels, while the “IS200” is the base hardware common in Mark VI. The two listed together usually indicates compatible revisions for different installed bases—handy if you manage mixed fleets or are planning phased replacements.

Key Features

• GE Mark VI/VIe & EX2100 compatibility – Typically used as a field I/O/terminal and conditioning board within turbine and excitation cabinets.
• Drop-in service replacements – IS215WETAH1BB and IS200WETAH1AGC are commonly paired for mixed installed bases, simplifying maintenance planning.
• Stable signal conditioning – Designed to handle noisy plant environments, helping reduce nuisance trips and erratic readings.
• No separate external power – Powered via backplane or I/O interface; cuts wiring complexity.
• Rugged terminal connectivity – Field-proven screw or plug-in terminals for fast, reliable installation and service.
• Revision-coded hardware – H1 hardware group; the BB/AGC codes help matching with controller firmware and cabinet drawings.

Technical Specifications

Application Fields

These boards show up in a few familiar spots:

• Gas/steam turbine control panels (Mark VI/Mark VIe)
• EX2100 excitation systems for generators
• Balance-of-plant I/O aggregation where robust terminal interfacing is needed

A maintenance engineer told us, “Swapping an IS200WETAH1AGC with the IS215WETAH1BB went smoothly—wiring stayed the same, and the controller came up clean after a routine checkout.” That seems to be the typical experience when revisions are matched to the cabinet drawings.

Advantages & Value

• Reliability – Industrial-grade design that typically holds up well in generator halls and turbine compartments.
• Compatibility – Suitable for existing Mark VI/VIe and EX2100 cabinets; reduces redesign or rewiring risk.
• Lifecycle savings – Like-for-like replacement limits downtime and engineering effort during outages.
• Technical support – Assistance with cross-references, revision matching, and installation checks before you schedule the outage.

Installation & Maintenance

• Cabinet environment – Install in a clean, ventilated control cabinet. Keep ambient within 0–60 °C and avoid condensation.
• Wiring practices – Use correct gauge and ferrules; separate low-level analog from high-voltage or contact switching leads to minimize noise.
• Grounding & shielding – Follow GE drawings for shield terminations; improper shields are a common cause of erratic readings.
• ESD safety – Handle boards with ESD protection; avoid touching components and edge fingers.
• Revision matching – Verify H1 and revision codes (BB vs. AGC) against your BOM and controller firmware notes before energizing—this avoids avoidable startup delays.
• Routine care – Periodic dust removal with dry air, torque-check terminal screws during outages, and record signal baselines to catch drift early.

Quality & Certifications

• Manufactured under ISO 9001 quality systems (supplier/manufacturer level)
• CE conformity and UL recognition typically apply at the system/cabinet level; board revisions are designed to meet those requirements when installed correctly
• RoHS status may vary by revision; we can check your exact part code if needed
• Warranty: 365 days
