GE IS200TBAIH1CDC Mark VIe | New Surplus Stock

Description

Product Introduction

The IS200TBAIH1CDC is the most advanced bearing analyzer input module in the Mark VIe line—revision C enhanced filtering, improved sensor diagnostics, extended-temperature rating, and conformal coating. It combines the best of all versions: the filtering and diagnostics of the H1C, the cold-rated performance of the extended-temp series, and the ruggedness of conformal coating. If your bearing health monitoring needs to be accurate and reliable in any environment, this is the module.

The “CDC” suffix tells you this is the revision C version with extended-temperature components and conformal coating. The input amplifiers are cold-rated. The diagnostics work at –40 °C. The board has conformal coating. The rest is the same: eight inputs, 16-bit resolution, 2,500 V isolation.

Key Technical Specifications

Quality Inspection Process (SOP Transparency)

The TBAIH1CDC gets the full thermal chamber treatment plus diagnostics tests—our 32-point inspection verifies accuracy, filtering, and diagnostics at –40 °C and +70 °C.

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 “–TBAIH1CDC” clearly.

Visual Inspection. Magnifying lamp, full board scan. Conformal coating must be continuous. The cold-rated amplifiers and diagnostic circuits are visually confirmed. 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, diagnostic test jig, and Tenney chamber.

• Cold soak (4 hours at –40 °C): Accuracy test—within ±0.25%. Filtering test—noise rejected. Sensor diagnostics—open, short, degradation detected.
• Hot soak (4 hours at +70 °C): Same tests—specs must hold.
• Isolation test: 2,500 V RMS—no breakdown.
• Thermal cycle: 3 cycles from –40 to +70 °C.
• 24-hour soak at 50 °C.

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, thermal cycle log, and a photo.

Field Replacement Pitfalls

The TBAIH1CDC handles temperature extremes and advanced 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 work at –40 °C. Keep them enabled.

Cold Temperature Input Drift—The “CDC” Holds Accuracy. The cold-rated amplifiers maintain accuracy at –40 °C. But the field sensor might drift—use a sensor rated for –40 °C.

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

ESD. The input circuits are sensitive. Strap up.

New Original vs. Refurbished: Why It Matters

The TBAIH1CDC has cold-rated amplifiers, diagnostic circuits, and conformal coating—refurbishers can’t add these.

What “New Original (New Surplus)” means. This IS200TBAIH1CDC came from GE’s factory with all the enhancements. We break the seal only for testing.

Refurbished risk in plain terms. A refurbisher may buy a standard TBAIH1A, clean it, and sell it as a “CDC.” At –40 °C, the standard amplifiers drift and the diagnostics fail. I’ve tested refurbished “CDC” units that were actually standard TBAIH1As—they failed the cold soak accuracy and diagnostics tests. Failure rate on refurbished extended-temp bearing analyzer modules runs 5× higher than new.

Real cost of a refurbished failure. A vibration signal drifts at –35 °C—bearing damage goes undetected—bearing failure—100,000. The refurbished module saved you 1,100. The failure cost you 90× that.

What we provide as proof. For every IS200TBAIH1CDC 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, thermal cycle log, 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 extended-temperature advanced diagnostics testing, and a 12-month warranty.
