GE IS200TBAIH1C Mark VIe | New Surplus Stock

Description

Product Introduction

The IS200TBAIH1C is the revision C version of the turbine bearing analyzer input module. GE added improved self-diagnostics, sensor health monitoring, and enhanced filtering to give you proactive maintenance capabilities. If you’ve got a turbine where bearing health is critical, this is the module that helps you catch problems before they become failures.

The “TBAIH1C” designation tells you this is the revision C bearing analyzer input module. The module has eight isolated inputs for accelerometers, proximity probes, and 4–20 mA temperature sensors. It has 16-bit resolution, enhanced filtering, and improved sensor diagnostics that detect open circuits, shorts, and sensor degradation. All inputs are isolated to 2,500 V.

Key Technical Specifications

Quality Inspection Process (SOP Transparency)

The TBAIH1C gets the full test regimen—our 30-point inspection verifies accuracy, filtering, and the improved diagnostics.

Incoming Verification. OEM packing slip matched to GE’s serial database. We log the serial and photograph the anti-static bag before cutting. The holographic GE label gets a UV check. The PCB edge must read “–TBAIH1C” clearly.

Visual Inspection. Magnifying lamp, full board scan. The diagnostic circuits are inspected. The 96-pin backplane connector shows zero wear.

Live Functional Test. Mark VIe test rack with a signal generator (accelerometer simulator, proximity probe simulator, 4–20 mA source), reference meter, and diagnostic test jig.

• Accuracy test: Simulate signals—verify accuracy.
• Filtering test: Inject noise—verify filtering.
• Sensor diagnostics test: Open circuit—detected. Short circuit—detected. Sensor degradation—detected.
• Isolation test: 2,500 V RMS—no breakdown.
• 24-hour soak.

Electrical Parameters. Insulation resistance: 500 VDC via Megger MIT420, >20 MΩ. Ground continuity: <0.1 Ω.

Firmware Verification. Read the FPGA firmware via ToolboxST—verify the checksum.

Final QC & Packaging. The QC report includes accuracy, filtering, sensor diagnostics, isolation test, and a photo.

Field Replacement Pitfalls

The TBAIH1C has improved diagnostics—installation mistakes are similar to other versions.

Sensor Type—Program It Correctly. Configure each input for the correct sensor type.

Diagnostics—Enable Them. The sensor diagnostics are valuable. Keep them enabled.

Grounding—Use Shielded Cable. Use shielded cable and ground the shield at one end only.

Filtering—Enable It. The enhanced filtering rejects noise.

ESD. The input circuits are sensitive. Strap up.

New Original vs. Refurbished: Why It Matters

The TBAIH1C has advanced diagnostics—refurbishers often can’t verify the diagnostic features.

What “New Original (New Surplus)” means. This IS200TBAIH1C came from GE’s factory, never mounted. The diagnostic circuits are fresh. We break the seal only for testing.

Refurbished risk in plain terms. The diagnostic circuits can degrade. A refurbished TBAIH1C may not detect sensor faults. I’ve tested refurbished TBAIH1C units where the diagnostics failed. Failure rate on refurbished bearing analyzer modules runs 4× higher than new.

Real cost of a refurbished failure. A sensor degrades—the diagnostics don’t detect it—the bearing fails—100,000. The refurbished module saved you 1,000. The failure cost you 100× that.

What we provide as proof. For every IS200TBAIH1C we ship: a photo of the OEM packing slip, serial traceability to GE’s records, a full test report that includes accuracy, filtering, sensor diagnostics, isolation test, and a sealed anti-static bag.

Pricing context. Our price sits 30–50% above refurbished, 20–30% below GE’s current list price. The delta covers our sourcing, our advanced diagnostics testing, and a 12-month warranty.

Performance Benchmarks & Test Results

Data from our Mark VIe test rack (ambient 45 °C, supply +5.0 VDC, ToolboxST v5.3, signal generator, reference meter, diagnostic test jig, hi-pot tester).

• Accuracy: Within ±0.1%.
• Filtering: Noise rejected.
• Open circuit detection: Detected.
• Short circuit detection: Detected.
• Sensor degradation detection: Detected.
• Isolation test: 2,500 V RMS—no breakdown. Insulation resistance >100 MΩ.
• Thermal performance: At 60 °C ambient, the module ran at 56 °C—under the 85 °C rating.
• Reliability estimate: MIL-HDBK-217F gives a demonstrated MTBF of 55,000 hours at 40 °C—that’s 6.3 years.
