Key Features:
- 16-channel high-density design maximizes I/O points in limited cabinet space, reducing per-point cost
- Channel-level open-circuit diagnostics for precise fault detection and predictive maintenance, minimizing mean time to repair (MTTR)
- Configurable input filtering suppresses mechanical contact bounce to prevent false triggers
- Supports full redundancy integration for SIL2/SIL3 safety instrumented systems (SIS)
- Hot-swappable for module replacement during system operation
Applications:
- Oil and gas, chemical, and power generation industries for critical process control
- Machine control systems for monitoring limit switches, emergency stop buttons, and safety interlocks
- Modernization of legacy Bailey INFI 90 control systems
