Key Features

1. Integrated 4-In/2-Out Analog Current-Source Design
   • Combines four 4–20 mA current inputs and two 4–20 mA current outputs in one compact block, reducing hardware complexity and cabinet space.
   • Each input provides 24 VDC loop power for direct connection to 2-wire transmitters (e.g., pressure, temperature, flow sensors) without external power supplies.
2. High Precision & Signal Integrity
   • Delivers ±0.1% input accuracy and ±0.15% output accuracy with 12-bit resolution, ensuring reliable, repeatable measurements and control.
   • Features 1500 V RMS isolation between channels, groups, and the Genius bus, eliminating ground loops and protecting against electrical transients in harsh industrial environments.
3. Software-Configurable & Scalable
   • Supports user-defined linear scaling to convert raw analog values into engineering units (e.g., °C, bar, m³/h) via configuration software.
   • Connects seamlessly to the Genius distributed I/O network, allowing expansion of analog I/O points across large plants without rewiring the main PLC panel.
4. Comprehensive On-Board Diagnostics
   • Detects input open wire, overrange/underrange, and high/low alarm conditions.
   • Monitors output feedback errors and internal faults, reporting status to the PLC for predictive maintenance and quick troubleshooting.
5. Rugged Industrial-Grade Construction
   • Operates reliably in extreme temperatures (-40°C to +70°C) and high humidity, suitable for outdoor and harsh process environments.
   • Requires no user calibration during installation or maintenance, reducing downtime and service costs.
