GE IC693ALG221J

  • Product Introduction: This is the “J” revision of the IC693ALG221 2-channel analog input module for the GE Fanuc 90-30 PLC platform. The “J” suffix indicates a specific hardware revision, typically associated with updated component sourcing, improved connector types, or enhanced diagnostic features. Functionally it is identical to the ALG221 but may include improved terminal connections, better LED visibility, or updated firmware for compatibility with newer 90-30 CPU revisions. It accepts both voltage (0-10V, 0-5V, 0-1V) and current (0-20mA, 4-20mA) signals with 12-bit resolution.

Description

GE IC693ALG221J

  • Technical Specifications:
    • Channels: 2 independent analog input channels
    • Input Type: Voltage or Current — software selectable
    • Resolution: 12-bit (4096 counts)
    • Accuracy: Plus or minus 0.2% of full scale
    • Linearity: Plus or minus 0.1% of full scale
    • Sampling Rate: 10 samples per second per channel
    • Isolation: 500V RMS channel-to-channel, 500V RMS channel-to-bus
    • Power Consumption: Approximately 1.5W
    • Operating Temperature: 0°C to 60°C
    • Input Impedance: 10 megohms (voltage), 250 ohms (current)
  • Functional Features:
    • Same 2-channel mixed-signal capability as ALG221
    • Enhanced LED indicators for improved diagnostics
    • Updated terminal design for easier wiring (J revision often improves terminal access)
    • Compatible with all 90-30 CPUs including latest firmware revisions
    • Backplane-powered
  • Application Scenarios:
    • Same as ALG221: mixed-signal machine control, process monitoring
    • Applications requiring the latest revision for regulatory compliance
    • Retrofit projects where newer revision is required
  • Performance Parameters:
    • Common Mode Rejection: Greater than 90dB
    • Bus Speed: Genius Bus, 10Mbps
    • MTBF: Greater than 150,000 hours
  • Material Composition:
    • Housing: UL94 V-0 ABS/polycarbonate blend
    • PCB: 4-layer FR-4 with updated components
    • Connectors: Gold-plated backplane connector, improved screw terminals
    • Isolation: Standard opto-isolators
  • Structural Features:
    • Same IC693 half-width form factor as
    • 2 green LEDs with improved brightness
    • Updated screw terminals for easier field wiring
    • DIN-rail mountable
  • Working Principle:
    • Identical to ALG221: voltage signals are buffered and digitized by 12-bit ADC; current signals are converted via 250 ohm shunt resistor then digitized. Digital values are transmitted to CPU via Genius Bus with optical isolation.
  • Installation Requirements:
    • Same as ALG221
    • Verify chassis supports “J” revision module (most do)
    • Use shielded twisted-pair cable
  • Usage Precautions:
    • Same as ALG221
    • The “J” revision terminals may have different torque specifications — check the datasheet
    • Do not mix revisions in the same chassis unless confirmed compatible
