GE IC693ALG223

  • Product Introduction: This is a 4-channel analog input module for the GE Fanuc 90-30 PLC platform. It is the 4-channel counterpart to the ALG221, providing 4 independent inputs that can each be configured for voltage (0-10V, 0-5V, 0-1V) or current (0-20mA, 4-20mA) signals. It offers 12-bit resolution (4096 counts per channel) and is used in applications requiring more analog inputs than the ALG221 provides but where 16-bit resolution (as in ACC302) is not required. It is a cost-effective solution for general-purpose process and machine control.

  • Working Principle:
    • Each channel independently accepts voltage or current signals. Voltage signals are buffered and fed to a 12-bit ADC. Current signals pass through a 250 ohm shunt resistor for voltage conversion before ADC sampling. The digital values are stored in internal registers and read by the CPU via the Genius Bus. Optical isolation protects the CPU from field-side electrical noise.
  • Installation Requirements:
    • Mount in IC693 or IC695 chassis
    • Use shielded twisted-pair cable for all analog signals
    • Ground cable shields at the chassis end only (single-point grounding)
    • Keep analog cables separated from digital I/O cables by at least 15cm
    • For voltage inputs, ensure source impedance is below 1k ohm
  • Usage Precautions:
    • Do not exceed 10V on any voltage input channel
    • Do not exceed 24mA on any current input channel
    • Configure each channel’s input type in software to match the field device
    • Calibrate zero and span in software for best accuracy
    • Do not run analog cables parallel to high-power AC cables
