GE IS200TBAOH1C Mark VIe | New Surplus Stock

Description

Product Introduction

The IS200TBAOH1C is the revision C version of the turbine bearing analyzer output module. GE added output loop diagnostics—open circuit and overload detection—so you know when your output signal path is compromised. It’s the most advanced bearing analyzer output module in the Mark VIe line.

The “TBAOH1C” designation tells you this is the revision C output module. The module has eight isolated analog outputs (4–20 mA) that can drive up to 750 Ω loads. It has 12-bit resolution, improved accuracy, and built-in output loop diagnostics. All outputs are isolated to 2,500 V.

Key Technical Specifications

Quality Inspection Process (SOP Transparency)

The TBAOH1C gets the full test regimen plus diagnostics verification—our 28-point inspection verifies accuracy, load drive, and output 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 “–TBAOH1C” clearly.

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

Live Functional Test. Mark VIe test rack with a precision current meter, load bank, and diagnostic test jig.

• Output test: Command 4 mA, 12 mA, and 20 mA—verify accuracy.
• Load test: Verify the outputs can drive up to 750 Ω.
• Open circuit detection: Open the loop—verify detection.
• Overload detection: Overload the output—verify detection.
• 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 output accuracy, load test, diagnostics, isolation test, and a photo.

Field Replacement Pitfalls

The TBAOH1C has diagnostics—installation mistakes are similar to other versions.

Output Load—750 Ω Maximum. The outputs can drive up to 750 Ω. Use an external amplifier if your load is higher.

Diagnostics—Enable Them. The output diagnostics detect open circuits and overloads. Keep them enabled.

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

Output Range—Program It. Set the output range to match your monitoring system.

ESD. The output circuits are sensitive. Strap up.

New Original vs. Refurbished: Why It Matters

The TBAOH1C has advanced diagnostics—refurbishers often can’t verify the diagnostic features.

What “New Original (New Surplus)” means. This IS200TBAOH1C 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 TBAOH1C may not detect an open circuit. I’ve tested refurbished TBAOH1C units where the diagnostics failed. Failure rate on refurbished output modules runs 4× higher than new.

Real cost of a refurbished failure. An output loop is open—the diagnostics don’t detect it—external monitor shows a wrong reading—operator misses a bearing issue—bearing failure—100,000. The refurbished module saved you 700. The failure cost you 142× that.

What we provide as proof. For every IS200TBAOH1C we ship: a photo of the OEM packing slip, serial traceability to GE’s records, a full test report that includes output accuracy, load test, output 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 output 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, precision current meter, load bank, diagnostic test jig, hi-pot tester).

• Output accuracy—4 mA: Output 4.00 mA—within ±0.05%.
• Output accuracy—12 mA: Output 12.01 mA—within ±0.05%.
• Output accuracy—20 mA: Output 20.00 mA—within ±0.05%.
• Load test: 750 Ω load—output maintained accuracy.
• Open circuit detection: Detected.
• Overload detection: Detected.
• Isolation test: 2,500 V RMS—no breakdown. Insulation resistance >100 MΩ.
• Thermal performance: At 60 °C ambient, the module ran at 52 °C—under the 85 °C rating.
• Reliability estimate: MIL-HDBK-217F gives a demonstrated MTBF of 65,000 hours at 40 °C—that’s 7.4 years.
