IS215VPROH2BC | Mark VIe Turbine Controller | New Surplus

Description

Product Introduction

The GE IS215VPROH2BC is a VMEbus high-performance processor board from the Mark VIe Speedtronic series, purpose-built as the primary computational engine for heavy-duty turbine control in power generation and oil & gas applications. This board executes turbine protection logic, speed/load control, and sequence-of-events recording—the core intelligence of the Mark VIe control system. The “BC” suffix indicates a conformal coated board with enhanced moisture and contaminant resistance for harsh environments, combined with the high-performance H2B revision features.

What sets the VPROH2BC revision apart is its 400 MHz PowerPC processor, 256 MB SDRAM, 128 MB flash memory, dual Gigabit Ethernet ports, advanced diagnostic capabilities, and the acrylic conformal coating that protects critical processor and memory circuitry from humidity, salt spray, and airborne particulates. This translates to faster application execution, significantly more headroom for complex control algorithms, improved data logging, and faster communications—all with environmental protection for demanding installations. For system integrators requiring the highest performance with environmental protection, this board is the direct OEM solution.

Key Technical Specifications

Key Selling Points & Differentiators

• Conformal Coated for Harsh Environments: The “BC” suffix provides acrylic coating that protects critical processor and memory circuitry against humidity, salt spray, and airborne contaminants—ideal for offshore platforms, coastal plants, and high-humidity installations.
• Faster Processor: 400 MHz vs. 300 MHz—33% faster execution for complex control algorithms.
• Double Memory Capacity: 256 MB SDRAM and 128 MB flash—twice the memory of H1B.
• Gigabit Ethernet: Dual 10/100/1000Base-T ports for faster communications and data transfer.
• Performance Headroom: Increased memory and processing power reduce page faults and enable more deterministic scan times.
• Live Test Verified: Every board undergoes a 48-hour burn-in running actual turbine simulation loops. We log all Ethernet handshakes, VME arbitration cycles, and I/O scan times. Coated boards are visually inspected for complete coverage and absence of bubbles.
• 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.
• Configuration Backup Service (Free): Upon request, we extract and archive your existing board’s firmware version and application config before shipment.

Frequently Asked Questions (FAQ)

Q: What does the “BC” suffix mean on IS215VPROH2BC?

A: The “BC” indicates conformal coating combined with the H2B high-performance revision. Specifically, it means the board has an acrylic conformal coating (0.02–0.05 mm) applied to the entire PCB assembly for moisture and contaminant protection, along with all H2B features (400 MHz processor, 256 MB SDRAM, dual Gigabit Ethernet). The coating adds protection; the H2B features provide high-performance processing capability.

Q: What is the difference between IS215VPROH2B and IS215VPROH2BC?

A: The H2B is non-coated; the H2BC has conformal coating. The coating protects against humidity, salt fog, and chemical vapors. If your cabinet is in a coastal area, offshore platform, or high-humidity environment, the BC variant is strongly recommended. In a clean, climate-controlled room, the H2B is sufficient and costs less. If your existing board is coated, you must replace it with a coated board (BC) because the uncoated version will fail faster in that environment.

Q: Does the conformal coating affect processor performance or thermal dissipation?

A: No. The coating is applied after functional testing, so it does not affect the electrical characteristics of the processor or memory circuits. Performance and thermal characteristics are identical to the non-coated H2B. The coating only provides environmental protection.

Q: Can I replace an H1B board with an H2BC?

A: Yes—with a firmware caveat. The H2BC will physically fit in the same VME slot and has the same connector pinout. However, you must be running Mark VIe Toolkit v6.5 or higher. Additionally, your application from H1B may need to be recompiled for the H2B platform. We strongly recommend testing in a spare rack before production deployment.

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.

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, you’ll need to reload from your backup file.

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

A: We stock these on the shelf—usually ship within 24 hours. For international orders, add 3–5 days for customs. If you need expedited (overnight air), coordinate with our logistics team.

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

A: To be direct: no. The IS215VPROH2BC 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.

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

A: If the board passes our QC test but doesn’t clear your turbine fault, accept a return within 30 days provided no physical damage. We charge a 15% restocking fee if the fault was due to application mismatch. We’ll diagnose with you before shipping.
