GE IC693ACC302A

  • Product Introduction: This is the “A” revision of the IC693ACC302 analog input module for the GE Fanuc 90-30 PLC platform. The “A” version is typically an earlier production revision with standard accuracy specifications. It is functionally equivalent to the ACC302 and ACC302B but may have slightly wider accuracy tolerances and different component sourcing. It provides 4 channels of 4-20mA analog input with 16-bit resolution and is used in general-purpose process control applications where the highest accuracy is not critical.

    • 4 green LED indicators
    • Screw-terminal field wiring
    • DIN-rail mountable
  • Working Principle:
    • Identical to ACC302: 4-20mA current is converted to voltage via internal 250 ohm resistor, sampled by 16-bit ADC, and transmitted to CPU via Genius Bus.
  • Installation Requirements:
    • Same as ACC302
    • Mount in IC693 or IC695 chassis
    • Use shielded twisted-pair for analog signals
    • Ground shield at one end only
  • Usage Precautions:
    • Same as ACC302
    • The “A” version uses standard components — do not assume it has the improved drift specifications of the “B” version
    • Calibrate zero and span in software for best results
