Key Features

1. High-Density 16-Channel Design
   • Integrates 16 independent single-ended current input channels in a compact half-height form factor, optimizing cabinet space and reducing system costs.
   • Supports simultaneous sampling of multiple field signals, ideal for large-scale process monitoring applications.
2. High Precision & Reliability
   • 16-bit ADC resolution ensures accurate capture of subtle signal changes, critical for precise process control.
   • ±0.1% FS accuracy and excellent linearity minimize measurement errors in industrial environments.
   • Rugged industrial-grade construction with wide temperature tolerance (-40°C to +70°C) delivers stable performance in extreme conditions (dust, moisture, vibration).
3. Flexible Signal Compatibility
   • Accepts industry-standard 4–20 mA and 0–20 mA current signals, compatible with most industrial sensors (temperature, pressure, flow, level) and transmitters.
   • Supports both 2-wire and 3-wire transmitter wiring, adapting to diverse field installation requirements.
4. Advanced Diagnostics & Protection
   • Built-in diagnostic functions detect overrange, underrange, open-circuit, and short-circuit conditions, enabling real-time fault alerts and quick troubleshooting.
   • High isolation (250 VAC continuous) protects the PLC backplane and other modules from electrical noise, voltage spikes, and ground loops, enhancing system safety.
5. Easy Integration & Maintenance
   • Seamless compatibility with GE Fanuc Genius I/O networks and Series 90-30/90-70 PLCs, enabling plug-and-play installation via the Field Control backplane.
   • Modular design simplifies system expansion and replacement, reducing maintenance time and downtime.
   • No user calibration required; factory-calibrated for immediate deployment.
