Description
The VMIC VMIVME-2128 is a 128-bit high-voltage digital output board designed for VMEbus-based industrial and embedded control systems. It provides 128 digital output channels through high-current sink drivers and supports output voltages in the high-voltage range required by industrial loads. The board incorporates Built-in-Test (BIT) logic for software-controlled fault isolation and includes protection features for surge current, thermal conditions, and inductive flyback.
The VMIVME-2128 uses a 6U VME form factor and supports 8-, 16-, and 32-bit data transfers. Its open-collector outputs are designed for external load switching, while the VMEbus interface provides integration with compatible VME controllers and intelligent I/O systems.

The original VMIVME-2128 documentation specifies 128 outputs, 600 mA sink drivers, 55 V breakdown capability, and VMEbus compatibility. Abaco’s current documentation for the VME-2128A successor lists a 5–55 VDC I/O voltage range, while legacy VMIVME-2128 documentation commonly specifies 5–48 VDC output operation; the exact load voltage should therefore be checked against the installed board revision and application.
⚙️ Key Features
- 128 digital outputs: Provides 128 high-voltage digital output channels for VME-based control architectures.
- High-current switching: Output drivers support up to 600 mA sink current, making the board suitable for higher-current industrial loads.

- Built-in-Test: Integrated BIT logic allows software-controlled testing of board functions and assists with fault isolation.
- Inductive-load protection: Output clamp diodes provide protection against inductive flyback.
- Thermal protection: Thermal shutdown helps protect the output circuitry during abnormal operating conditions.
- Surge-current protection: Automatic surge-current shutdown provides additional protection for output drivers.
- Fail indication: A front-panel Fail LED is provided for diagnostic indication.
- Intelligent I/O integration: The board can be used with compatible intelligent I/O controllers and VME-based automation systems.
🔧 Application
The VMIVME-2128 is designed for VMEbus industrial control systems requiring a large number of discrete outputs. Typical applications include machine control, industrial automation, test equipment, process control, legacy embedded control systems, and systems using high-current or high-voltage discrete loads.
The board is particularly useful where many output points must be controlled from a single 6U VMEbus slot. Its BIT capability and diagnostic LED can assist maintenance personnel when troubleshooting installed legacy systems.
For replacement applications, verify the exact VMIVME-2128 variant, board revision, connector arrangement, output voltage, external load requirements, and VMEbus configuration before installation.
