GE IC693ACC302B

  • Product Introduction: This is the “B” revision of the IC693ACC302 analog input module for the GE Fanuc 90-30 PLC platform. It is functionally identical to the standard ACC302 but includes updated firmware, improved component tolerances, and enhanced diagnostic capabilities. The “B” suffix typically indicates a hardware revision with better temperature stability and tighter accuracy specifications. It accepts 4-20mA current loop signals and provides 16-bit resolution for precision process measurement. This module is used in the same applications as the ACC302 but offers improved long-term stability for critical process control loops.

    • Span Drift: Less than 0.005% of full scale per degree Celsius (improved)
  • Functional Features:
    • Same 4-channel configuration as with enhanced accuracy
    • Improved diagnostic LED indicators for channel fault detection
    • Enhanced firmware for faster register update times
    • Better long-term stability for continuous process monitoring
    • Software-configurable input range (mA, mV, ohms)
    • Backplane-powered design
    • Compatible with all 90-30 CPUs and CIMPLICITY software
  • Application Scenarios:
    • Critical process control loops requiring high accuracy
    • Pharmaceutical manufacturing process monitoring
    • Food and beverage process instrumentation
    • Power plant boiler and turbine monitoring
    • Precision chemical dosing systems
    • Custody transfer flow metering
  • Performance Parameters:
    • Input Impedance: 250 ohms
    • Common Mode Rejection: Greater than 110dB (improved)
    • Noise Rejection: Greater than 85dB normal mode
    • Bus Speed: Genius Bus, 10Mbps
    • MTBF: Greater than 250,000 hours
  • Material Composition:
    • Housing: U94 V-0 polycarbonate (same as ACC302)
    • PCB: 4-layer FR-4 with tighter tolerance components
    • Connectors: Gold-plated edge connector, screw terminals
    • Isolation: Enhanced opto-isolators with better CTR (Current Transfer Ratio)
  • Structural Features:
    • Identical form factor to
    • 4 green LEDs with improved brightness for better visibility
    • Same screw-terminal field connections
    • DIN-rail or chassis mount
  • Working Principle:
    • Identical to ACC302: 4-20mA current flows through a 250 ohm shunt resistor, converting to 1-5V. A 16-bit ADC samples and converts to digital. The improved components reduce drift and noise, providing more stable readings over time and temperature variations.
  • Installation Requirements:
    • Same as ACC302
    • Ensure chassis firmware supports the “B” revision for full diagnostic capability
    • Use shielded twisted-pair cable
    • Single-point ground the shield
  • Usage Precautions:
    • Same as
    • Take advantage of the improved accuracy by calibrating in software
    • The “B” version is not backward-compatible with older firmware that expects standard ACC302 behavior — verify CPU firmware version before installation
