Overview

The VMIVME 3215-000 is a rugged 6U single-slot VMEbus digital input/output module originally manufactured by VMIC / GE Intelligent Platforms, widely deployed for discrete signal control and status acquisition in mission-critical VME-based systems. It is a core I/O component for GE Mark VI gas turbine control systems, used to interface the VME controller with field switches, contact sensors, relays and solenoid actuators.

This board provides 16 optically isolated digital inputs and 16 optically isolated digital outputs, delivering high noise immunity for industrial field wiring. As an end-of-life (EOL) legacy VME hardware, brand-new original production stock is no longer available. We supply fully tested refurbished and surplus VMIVME 3215-000 spare boards for turbine control, industrial test benches and aerospace ground support equipment replacement and system maintenance projects.

All channels feature independent opto-coupler isolation, protecting the VME backplane and controller electronics from surge voltage, ground loop noise and transients from field devices. Memory-mapped register design enables simple read/write access over VMEbus for fast discrete state monitoring and control output.

Core Features

• 32 Total Discrete Channels: 16 optically isolated digital inputs + 16 optically isolated digital outputs in one 6U VME slot
• High-Voltage Optical Isolation: 2500V AC isolation per channel, eliminates ground loop interference and protects VME chassis electronics
• Dual Input Compatibility: Digital inputs support both dry contact and wet contact field sensor wiring
• Transistor Output Drivers: Each digital output channel rated up to 0.5A load capacity for driving relays, indicators and solenoid loads
• Standard VMEbus Slave Interface: Supports A16/A24 address space, D8/D16/D32 data transfers, programmable VME interrupts
• Built-In Channel Diagnostics: Onboard status registers for channel fault detection, open/short circuit monitoring and self-test capability
• Rugged 6U VME Form Factor: Single slot design, fits standard VME backplanes, shock and vibration hardened for continuous industrial operation
• Legacy System Compatibility: Native integration with GE Mark VI turbine control platform and classic VMIC VME CPU boards

Working Principle

The VMIVME 3215-000 acts as a galvanic isolation bridge between the VME control backplane and noisy field-side discrete wiring.

For input channels: Field contact or sensor signals trigger optocouplers. The board latches the digital state of each input and stores it in memory-mapped registers. The VME host controller reads these registers to monitor switch status, limit signals and equipment interlock conditions.

For output channels: The VME host writes control values to output registers. Logic signals drive optocouplers and power transistor outputs to energize field relays, solenoids or status indicators. The optical barrier physically separates the field high-side wiring from the sensitive VME backplane circuit, preventing damage from field surges and EMI noise.

Onboard diagnostic logic continuously monitors channel health and can trigger VME interrupts when fault conditions are detected.

Application Fields

• Gas Turbine Control (GE Mark VI System): Primary use case for turbine interlock signals, valve status feedback, relay drive and emergency trip discrete I/O
• Power Generation & Energy Control: Power plant auxiliary control, generator protection interlock monitoring
• Aerospace Ground Support Test Equipment: VME-based test racks, discrete signal simulation and equipment interlock control
• Automated Test Equipment (ATE): Switch matrix control, relay actuation and contact status capture
• Heavy Industrial Automation: Large machinery safety interlock systems, plant discrete monitoring and control
• Defense & Naval VME Legacy Systems: Rugged discrete I/O for mission-critical VME control platforms

Product Advantages

1. High galvanic isolation: 2500V AC opto-isolation per channel suppresses ground loops and electrical transients common in power plant environments.
2. High channel density: 16-in /16-out integrated into one single 6U VME slot, saving valuable chassis slots in compact VME racks.
3. Seamless Mark VI integration: Designed natively for GE Mark VI turbine control, no custom driver modification required for replacement spare boards.
4. Built-in diagnostic self-test: Channel-level fault reporting reduces troubleshooting downtime for critical power systems.
5. Drop-in replacement: Standard VME pinout and register mapping, simple swap for failed original VMIVME 3215-000 boards without system redesign.

FAQ

Q1: Is the VMIVME 3215-000 still manufactured new?

A: Original production is discontinued (EOL). We stock fully tested refurbished and surplus spare units for legacy system maintenance.

Q2: What is the main application of VMIVME 3215-000?

A: It is most widely used as discrete I/O board for GE Mark VI gas turbine control systems, handling interlock, trip signals and relay control.

Q3: Can this board be used outside Mark VI turbine systems?

A: Yes. It works as a general-purpose isolated digital I/O VME card for any VMEbus system, but register configuration and software drivers need custom setup for non-Mark VI applications.

Q4: What is the isolation rating?

A: Each channel features 2500V AC optical isolation between field wiring and VME side circuitry.
