Key Features:
- High-density 16-channel design in a single-width module to reduce cabinet space and per-point cost while maintaining precision
- Intelligent diagnostics including per-channel LED indicators, wire break detection (below 2.5 mA), over/under-range alarms, and module status LEDs
- HART transparency enables asset management tools to communicate with smart field devices via DCS without multiplexers
- SIL 2 capability for functional safety applications like burner management or pressure interlocks when used in certified architectures
- High common mode rejection ratio (CMRR) to eliminate ground loop errors from nearby variable frequency drives
- Low drift (less than 0.05% per degree Celsius) for consistent signal accuracy across temperature changes
Applications:
- Process control in chemical, pharmaceutical, mining, power, and petrochemical industries
- Monitoring of temperature, pressure, flow, and level signals from industrial sensors and transmitters
- Functional safety systems requiring SIL 2 compliance
- Data collection for batch processing and quality control in manufacturing
