⚙️ Emerson 1C31110G01 Ovation Digital Input Module
High-density digital signal acquisition for Emerson Ovation distributed control systems. The 1C31110G01 converts field-level discrete signals—limit switches, push buttons, proximity sensors—into controller-readable data with millisecond response times.
🎯 Real-World Applications
Valve Position Feedback: Monitor open/closed status of motor-operated valves in pipeline networks. Each input channel confirms actuator position, enabling automated sequencing and preventing deadhead conditions.
Emergency Shutdown Systems: Interface with safety-rated sensors (flame detectors, gas monitors, E-stop buttons) to trigger protective actions. Configurable input filtering rejects nuisance trips while maintaining SIL-rated integrity.
Production Line Monitoring: Track part presence, conveyor jams, and quality gates across manufacturing cells. Timestamp each state change for OEE analysis and root-cause diagnostics.
💡 Intelligent Input Processing
Unlike basic I/O cards, the 1C31110G01 features programmable debounce filters that eliminate contact chatter from mechanical switches. Adjustable time constants (1-100ms) match sensor characteristics, reducing false alarms in high-vibration environments like compressor stations.
Diagnostic LEDs on each channel provide instant visual feedback—green for active high, off for low, red for wire-off faults. Technicians troubleshoot wiring errors without laptop tools, cutting commissioning time by 40%.

🔧 System Integration
Mounts directly to Ovation controller chassis via high-speed backplane. Auto-discovery protocol eliminates manual addressing—controller firmware detects module type and allocates I/O tags automatically. Hot-swap capability allows replacement during operation without process shutdown.
Compatible with: Ovation 3.5+ controllers, WinTools configuration software, and third-party SCADA via OPC DA/UA gateways.
