Key Features

1. High-density integrated design
    
   16-channel single module reduces cabinet I/O slot occupation, lower spare parts inventory cost compared with 8-channel modules.
2. Native HART all-in-one function
    
   No additional HART expansion card required; simultaneously collect analog process value and digital instrument diagnostic information, realize intelligent field device management.
3. Complete self-diagnosis system
    
   Real-time detection of loop open circuit, short circuit, over-range, module communication failure, channel abnormal alarm, fault status uploaded to Experion SCADA system.
4. Redundancy support
    
   Can be paired with redundant IOTA terminal base to realize full channel redundancy, suitable for high-reliability critical process loops.
5. Hot plug & play maintenance
    
   Module can be replaced online without stopping the whole controller, minimize production downtime during maintenance.
6. Wide signal compatibility
    
   Adapt to 2-wire loop-powered transmitters and self-powered voltage signal sensors, covering pressure, temperature, flow, liquid level all standard process measuring instruments.
