Abaco Systems / VMIC VMIVME-1110-0-12-10-1-1 64-Bit High-Voltage Digital Input Board

The Abaco Systems / VMIC VMIVME-1110-0-12-10-1-1 is a 64-bit high-voltage digital input board engineered for VMEbus-based systems requiring monitoring of diverse signal sources and input voltage ranges. The board provides 64 digital input channels with configurable signal conditioning, supporting current sink and voltage source configurations alongside selectable input filtering and hysteresis for clean, reliable signal acquisition.

– Technical Specifications

• Input Channels: 64 digital inputs
• Data Transfer: 8-, 16-, and 32-bit transfers supported; jumper-selectable for supervisory or nonprivileged short I/O memory space access
• Signal Sources: Electronic switching circuits, standard logic circuits, mechanical switch contacts, relay contacts, Opto 22 type signal conditioning modules
• Input Signal Conditioning: Current sink or voltage source configurations; jumper-selectable with multiple filter options and built-in hysteresis
• Address Mapping: Two sets of board address switches for Control and Status Register (CSR) and I/O addresses; up to 13 jumpers for flexible short data I/O address selection; independently selectable CSR address with contiguous memory mapping
• Form Factor: Double Eurocard
• Connectors: High reliability DIN-type I/O

– Key Features

• Built-in-test (BIT) logic for fault detection and isolation
• Front panel Fail LED for rapid fault identification
• Test mode bits enabling tri-state outputs of CMOS test registers
• Selectable half-board test mode for live operation on remaining channels
• Megamodule family membership enabling common programming features across compatible boards

– Typical Applications

Multiplexed signal monitoring in industrial control systems, real-time telemetry acquisition, discrete event logging, and systems requiring simultaneous acquisition from both current-sinking and voltage-sourcing transducers.

– Compatibility & Integration

Fully VMEbus specification compatible with support for both supervisory and nonprivileged access modes. The board integrates into Megamodule-based systems leveraging standardized programming interfaces and address mapping schemes.
