Description
🔹 Product Description
The VMIC VMIVME-2128 is a 128-bit high-voltage digital output board with Built-in-Test (BIT) for VMEbus-based industrial and embedded control systems. The board provides 128 high-voltage output channels with high-current sinking capability and is designed for interfacing VMEbus controllers with external loads and field devices. It supports VMEbus-compatible A24/A16 addressing and 8-, 16-, or 32-bit data transfers.
The VMIVME-2128 incorporates automatic surge-current shutdown, thermal shutdown protection, output clamp diodes for inductive loads, and built-in diagnostic logic. Depending on the output configuration, the board can support external output voltages from 5 V through 48 V, with a maximum output voltage specification reaching 55 V.

🔹 Application
The VMIVME-2128 is intended for VMEbus control systems requiring a large number of discrete high-voltage outputs. It can interface with external industrial loads, actuators, relays, indicators, and other field devices where high-current sinking outputs are required.
Its Built-in-Test logic supports diagnostic testing of onboard active components, while output data registers provide read-back capability. A front-panel Fail LED provides an additional diagnostic indication.
🔹 Electrical Characteristics
The output stage supports different configurations. With the electronic-switch option and pull-up resistors, documented output-voltage configurations include 5 V, 12 V, 24 V, and 48 V, with up to 600 mA sink current. The absolute maximum output voltage varies by configuration and reaches 55 V for the 48 V option.
🔹 Replacement Notes
The original VMIVME-2128 / VME-2128 has reached end-of-life. Abaco Systems identifies the VME-2128A as its form-fit-function replacement. For an existing system, however, the original VMIVME-2128 may still be required where the installed software, cabling, connector arrangement, and system configuration depend on the original board.
Before replacement, verify the board revision, VMEbus address configuration, output-voltage configuration, connector wiring, external power arrangement, and load requirements.
