GE IS200TBAOH1CCB Mark VIe | New Surplus Stock

Description

Product Introduction

The IS200TBAOH1CCB is the most advanced bearing analyzer output module in the Mark VIe line—revision C diagnostics, 750 Ω load drive, extended-temperature performance, and conformal coating. It retransmits vibration and temperature signals to external systems with accuracy and reliability, even when the cabinet sits outside in the cold.

The “CCB” suffix tells you this is the revision C output module with extended-temperature components and conformal coating. The output drivers are cold-rated parts that maintain their accuracy and drive capability at –40 °C. The diagnostics (open circuit and overload detection) work at temperature extremes. The board has conformal coating. The rest is the same: eight outputs, 12-bit resolution, 2,500 V isolation.

Key Technical Specifications

Quality Inspection Process (SOP Transparency)

The TBAOH1CCB gets the full thermal chamber treatment—our 30-point inspection verifies accuracy, load drive, 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 “–TBAOH1CCB” clearly.

Visual Inspection. Magnifying lamp, full board scan. Conformal coating must be continuous. The cold-rated output drivers and diagnostic circuits are visually confirmed. The 96-pin backplane connector shows zero wear.

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

• Cold soak (4 hours at –40 °C): Output accuracy test—4 mA, 12 mA, 20 mA—within ±0.20%. Load test—750 Ω load—output maintains accuracy. Diagnostics—open circuit and overload detection work.
• 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 output accuracy at extremes, load test, diagnostics, isolation test, thermal cycle log, and a photo.

Field Replacement Pitfalls

The TBAOH1CCB handles temperature extremes—installation mistakes are similar to other output modules.

Output Load—750 Ω Maximum. The outputs can drive up to 750 Ω at –40 °C. Use an external amplifier if your load is higher.

Diagnostics—Enable Them. The diagnostics work at –40 °C. Keep them enabled.

Cold Temperature Output Accuracy—The “CCB” Holds Accuracy. The cold-rated output drivers maintain accuracy at –40 °C. But the receiving device might drift—use a device rated for –40 °C.

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

ESD. The output circuits are sensitive. Strap up.

New Original vs. Refurbished: Why It Matters

The TBAOH1CCB has cold-rated output drivers, diagnostics, and conformal coating—refurbishers can’t add these.

What “New Original (New Surplus)” means. This IS200TBAOH1CCB 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 TBAOH1A, clean it, and sell it as a “CCB.” At –40 °C, the standard output drivers drift and the diagnostics fail. I’ve tested refurbished “CCB” units that were actually standard TBAOH1As—they failed the cold soak accuracy and diagnostics tests. Failure rate on refurbished extended-temp output modules runs 5× higher than new.

Real cost of a refurbished failure. A vibration signal is off at –35 °C—external monitor shows the wrong reading—operator misses a bearing issue—bearing failure—100,000. The refurbished module saved you 800. The failure cost you 125× that.

What we provide as proof. For every IS200TBAOH1CCB we ship: a photo of the OEM packing slip, serial traceability to GE’s records, a full test report that includes output accuracy at –40 °C and +70 °C, 750 Ω load test, 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 output testing, and a 12-month warranty.
