This unit
The Abaco Systems / VMIC VMIVME-2528-110 is a 128-bit TTL digital I/O board engineered for VMEbus systems requiring high-density interfacing of digital devices and sensors. Packaged in a double Eurocard (6U) form factor, this board delivers 128 individually configurable I/O points across sixteen 8-bit ports, each addressable on 8- or 16-bit boundaries. The architecture supports both non-privileged and supervisory short I/O transfers, with twelve DIP switches enabling flexible address map selection within the short data I/O space.
Technical Specifications
- I/O Channels: 128 TTL-compatible input/output points organized as sixteen 8-bit ports
- Data Transfer: 8-bit and 16-bit transfers supported
- Form Factor: Double Eurocard (6U) per VMEbus specification (ANSI/IEEE STD 1014-1987, IEC 821, IEC 297)
- Output Current Sink: 24 mA
- Output Current Source: 6.5 mA
- I/O Connector: 64-pin DIN 41612 with alternating ground pins
- Operating Temperature: 0 to 55 °C
- Logic Configuration: High-true or low-true selectable; individual port direction controlled via jumpers
- Power-up Behavior: All outputs initialize in tristate mode; any write to the final port releases tristate
Key Features
- Individual port direction control jumpers for flexible input/output assignment
- Twelve DIP switches for unlimited short address map configuration
- Real-time loopback functionality for diagnostic and verification use
- Tristate management with automatic release on first port write
- Addressable to any location within short supervisory or short non-privileged I/O map
Typical Applications
- Industrial automation and process control
- High-channel-count data acquisition systems
- Digital sensor and device interfacing
- VMEbus-based instrumentation and test systems
