IS200VPROH1BCD | Mark VIe Processor Board | OEM New

Description

Product Introduction

The GE IS200VPROH1BCD is a VMEbus processor board from the Mark VIe Speedtronic series, purpose-built for heavy-duty turbine control in power generation and oil & gas applications. This board acts as the primary computational engine executing turbine protection logic, speed/load control, and sequence-of-events recording. The “BCD” suffix indicates an extreme environment conformal coated board with the highest level of moisture, chemical, and particulate protection available in this series.

What sets the H1BCD revision apart is the updated boot flash, increased SDRAM density, and the industrial-grade urethane conformal coating that provides maximum protection in the harshest operating conditions. This coating is rated for continuous exposure to high humidity, salt fog, chemical vapors, and airborne particulates—common in offshore platforms, coastal desalination plants, chemical processing facilities, and pulp and paper mills. For system integrators maintaining legacy Mark VIe cabinets in aggressive environments, this board is the direct OEM replacement—no adapter frames or firmware recompilation required if you match your existing revision level.

Key Technical Specifications

Key Selling Points & Differentiators

• Extreme Environment Coating Advantage: The “D” suffix provides the thickest, most robust industrial urethane coating (0.08–0.15 mm) rated for continuous exposure to high humidity, salt fog, chemical vapors, and airborne particulates. This is the preferred variant for offshore platforms, coastal installations, desalination plants, chemical processing, pulp and paper mills, and mining operations where environmental contaminants are severe.
• Revision H1BCD Advantage: Newer boot flash supports firmware updates without requiring a PROM burner. Earlier VPRO boards (H0xxx) needed external programming hardware.
• Live Test Verified: Every board undergoes a 48-hour burn-in running actual turbine simulation loops, not just a POST. We log all Ethernet handshakes, VME arbitration cycles, and I/O scan times. Coated boards are visually inspected for complete coverage, thickness consistency, and absence of bubbles, voids, or pinholes using magnification and UV light.
• 90-Day Warranty: Covers functional defects. If it fails under normal operating conditions, we replace it. No restocking fee for verified returns.
• OEM Traceability: All units come from audited surplus channels with original GE anti-static bags and serialized labels. No clones, no pull-and-refurbish from unknown sources.
• Configuration Backup Service (Free): Upon request, we extract and archive your existing board’s firmware version and application config before shipment, so you have a fallback if your new board needs the same image.
• Direct Drop-In: Matches existing Mark VIe backplane pinout and VME slot spacing. No mechanical modifications required—your cable harnesses and I/O terminations stay untouched.

Frequently Asked Questions (FAQ)

Q: What is the difference between IS200VPROH1BCA, H1BCB, H1BCC, and H1BCD?

A: The suffix letters indicate coating type and thickness. Here’s the breakdown:

• H1BCA: Non-coated—suitable for clean, climate-controlled environments
• H1BCB: Standard acrylic coating (0.02–0.05 mm) for moderate humidity protection
• H1BCC: Heavy urethane/acrylic coating (0.05–0.13 mm) for harsh environments with high humidity, salt fog, or chemical vapors
• H1BCD: Extreme industrial urethane coating (0.08–0.15 mm) for severe environments with continuous chemical exposure, salt spray, and particulates

Electrically and functionally they are identical—same processor, same memory, same firmware. The coating adds protection; it does not change performance. If your existing board is H1BCD, you must replace it with H1BCD because the thinner-coated or non-coated versions will fail faster in that environment. Conversely, in a clean room, the H1BCA is sufficient and costs less.

Q: Does the extreme coating affect heat dissipation or board fit?

A: Good question. The coating adds about 0.12 mm to the board thickness, which does not affect VME slot fitment—clearances are designed for it. Heat dissipation is marginally reduced (approximately 3–4% higher junction temperatures), but the board is rated for 0 to +55°C ambient with the coating applied. We’ve tested this on our burn-in racks; temperature rise is within GE’s specified limits. Do not remove the coating or scrape it off—it voids the warranty and compromises protection.

Q: I have an IS200VPROH1BCD with a different prefix or revision—can I just swap this in?

A: If your current board is exactly H1BCD, yes—direct swap. If you have H1B, H1C, or H1A (different revision levels), you need to check your Mark VIe Toolkit version first. Newer boards might not boot with firmware older than v5.8. In our experience, always pull a firmware version log from your existing board before swapping. We can guide you through that command-line check.

Q: Is this board hot-swappable?

A: No. The Mark VIe VME backplane does not support live insertion. You must de-energize the rack, ground yourself, and wait 30 seconds for bulk capacitors to discharge. We’ve seen field crews try to pull a VPRO while the cabinet was still on auxiliary power—it took out the backplane driver chips. Don’t risk it.

Q: How do I know this isn’t a counterfeit or a refurbished board sold as “new”?

A: We photograph each unit’s OEM packaging, serial number label, and anti-static bag before shipment. You’ll receive those images with your packing slip. Also, our QC process includes a visual inspection against GE’s known PCB marking standards—copper trace thickness, solder mask color, and component date codes. For extreme coated boards, we also check coating thickness with a micrometer at multiple points, inspect under UV light (urethane fluoresces), and perform a solvent resistance test on a small non-critical area. Counterfeits usually have mismatched font styles, uneven coating thickness, or visible bubbles. We reject about 18% of inbound stock for coating irregularities alone.

Q: Will I lose my turbine protection settings when I replace the board?

A: Yes and no. Application logic and setpoints are stored in the application flash and in the separate memory on the I/O boards, not primarily on the VPRO. However, the VPRO does hold the executive firmware and the boot configuration. If your old board is dead and you can’t extract the configuration, we can send you a blank board and you’ll need to reload from your backup file (.hex or .bin). If you don’t have a backup, we can, in some cases, transplant the flash ICs—but that’s a last-resort service, not covered under standard warranty.

Q: What is the typical lead time for this part?

A: We stock these on the shelf—usually ship within 24 hours of order placement and payment confirmation. For international orders, add 3–5 days for customs. If you need expedited (overnight air), we can do that, but you’ll need to coordinate with our logistics team for the cut-off time.

Q: Does this board work with the newer Mark VIeS (SIL-rated) cabinets?

A: To be direct: no. The IS200VPROH1BCD is not SIL-certified. It’s meant for standard Mark VIe industrial control. The SIL-rated systems use the IS220VPRO (with different component ratings and a separate safety watchdog). Mixing them violates your site’s safety integrity level. If you’re in a SIL environment, we can source the correct variant but it will have a different model number and longer lead time.

Q: What’s your return policy if it doesn’t solve my fault code?

A: If the board is electrically functional (passes our QC test) but doesn’t clear your turbine fault, we’ll accept a return within 30 days provided the board is still in anti-static packaging and shows no physical damage. We do charge a 15% restocking fee if the fault was due to your application mismatch (e.g., wrong firmware version). We’ll work with you over the phone or email to diagnose the fault before we ship, so we can avoid that scenario. Our goal is to get you running, not to ship boxes back and forth.
