Key Features

1. 64-Channel Optical Isolation
   • 64 independent optically isolated inputs eliminate electrical interference between field devices and the control system.
   • High-voltage isolation (up to 2,500 Vrms) protects against transient surges and ground potential differences.
2. Flexible Input Configuration
   • Multi-voltage compatibility (5/12/24/48 VDC) supports diverse field sensor and switch types.
   • Jumper-selectable positive/negative true logic adapts to various signal conventions.
   • 16 digital filter settings optimize signal integrity for fast or slow input transitions.
3. VMEbus Compliance & Integration
   • 6U double-height form factor fits standard VMEbus enclosures.
   • A16:D16/D08 slave interface ensures seamless compatibility with VMEbus-based CPUs and systems.
   • DIP-switch configurable base address enables easy system integration without firmware changes.
4. Robust Industrial Reliability
   • Wide operating temperature range (-20°C to +85°C) supports extreme industrial environments.
   • Ruggedized PCB and components withstand shock, vibration, and humidity (5%–95% non-condensing).
   • Built-In Test (BIT) functionality validates circuit integrity during power-up and operation.
5. Real-Time Monitoring & Diagnostics
   • Front-panel LED indicators display real-time input status and fault conditions for quick troubleshooting.
   • Supports remote monitoring and diagnostics via the VMEbus, enabling proactive maintenance.
