Functional Description

The VMIVME‑2170A module consists of:

• VMEbus interface logic with address decoding and transfer control

• Four 8‑bit output registers for structured digital I/O

• Optocoupler array providing isolation between outputs and the VMEbus

Optical isolation prevents ground loops and reduces susceptibility to electrical noise, making the board ideal for industrial environments with high electromagnetic interference.

The board operates within the VMEbus short I/O address space and supports both supervisory and non‑privileged I/O data transfers.

Typical Applications

The VMIVME‑2170A is commonly used in:

• Industrial automation and process control systems requiring robust digital outputs

• PLC and embedded VMEbus systems interfacing with actuators, relays, or digital sensors

• Systems where signal isolation is essential due to electrical noise or mixed‑voltage environments

• Legacy or retrofit applications where standard VMEbus boards are required for compatibility

Its design emphasizes stable and reliable digital output performance across varied industrial sectors.

Installation & Integration

To ensure correct operation:

• Install the board in a compatible VMEbus chassis supporting double Eurocard modules.

• Configure the onboard DIP switches to set the desired VMEbus address.

• Provide an appropriate external pull‑up supply voltage based on the system’s logic level requirements.

• Ensure secure mechanical and electrical connections to avoid noise or signal loss.

Integration with system software typically requires compatible device drivers that support VMEbus I/O operations.
