IS215VPROH1B | GE VPRO Processor Module | Original Packaging

Description

Product Introduction

The GE IS215VPROH1B is a VMEbus 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.

What sets the VPROH1B revision apart is its 128 MB SDRAM and 64 MB flash memory, dual-core processing capability, and enhanced diagnostics. This translates to faster application load times, more headroom for complex control algorithms, and improved fault tolerance through hardware-based watchdog monitoring. For system integrators maintaining or upgrading Mark VIe cabinets, this board is the direct OEM replacement for the primary control processor.

Key Technical Specifications

Key Selling Points & Differentiators

• Double Memory Capacity: 128 MB SDRAM and 64 MB flash—supports larger application code, more data logging points, and faster execution of complex turbine models.
• Fault-Tolerant Design: Hardware watchdog timer ensures deterministic recovery from software faults.
• Performance Headroom: The extra memory reduces page faults and swapping, resulting in more deterministic scan times—critical for protection functions.
• 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.
• 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.

Frequently Asked Questions (FAQ)

Q: What is the difference between IS215VPROH1B and IS200VPROH1B?

A: The IS215VPROH1B is a newer revision with improved diagnostics and firmware compatibility. Verify with your existing system before replacing. In most cases, they are interchangeable, but confirm with the board’s firmware requirements.

Q: What is the difference between IS215VPROH1B and IS215VPROH1A?

A: The H1B revision includes enhanced diagnostics and minor performance improvements over H1A. Check your existing board—if you have H1A, verify compatibility. In most cases, H1A and H1B are interchangeable, but confirm with the board’s firmware requirements.

Q: Can I replace an H1 board with an H1B?

A: Yes—with a firmware caveat. The H1B will physically fit in the same VME slot and has the same connector pinout. However, you must be running Mark VIe Toolkit v6.0 or higher. If you’re running an older toolkit, the board will not boot properly.

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: How do I know this isn’t a counterfeit or a refurbished board?

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. Our QC process includes a visual inspection against GE’s known PCB marking standards.

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 IS215VPROH1B 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.
