GE Fanuc RX3i IC694ALG220 | -10 to +10V Analog Card

Product Overview

The GE Fanuc IC694ALG220 provides high-precision analog data acquisition for the PACSystems RX3i platform. This 100% Brand New original module interfaces directly with field sensors to measure voltage signals across a wide range of -10 to +10 Volts. With four independent channels, the IC694ALG220 converts continuous analog signals into digital values for logic processing, making it an essential component for monitoring pressure, temperature, and position in complex industrial automation architectures.

Technical Specifications

Engineering Advantages

• High-Precision Signal Processing: The IC694ALG220 delivers superior accuracy when interpreting variable voltage signals. This precision allows the PACSystems RX3i CPU to make micro-adjustments in PID loops, ensuring stable operation in sensitive chemical and power generation processes.

• Bipolar Voltage Versatility: By supporting a full -10V to +10V range, this module accommodates a vast array of industrial sensors. You can integrate bipolar actuators and sensors without adding external signal conditioning hardware, reducing total system cost.

• Robust Noise Immunity: The module incorporates advanced filtering circuitry to reject electromagnetic interference (EMI). This ensures that signal integrity remains intact even when installed in cabinets alongside high-frequency variable speed drives or heavy switchgear.

• Seamless RX3i Integration: Designed for the high-speed RX3i backplane, the module transfers analog data with minimal latency. The system automatically recognizes the module through the hardware configuration tool, allowing for rapid deployment and diagnostic monitoring.

• Compact Footprint: Despite its four isolated channels, the module occupies only a single slot. This high-density design enables engineers to maximize I/O capacity in standard RX3i racks, ideal for space-constrained offshore or mobile skid applications.

FAQs

• Does the IC694ALG220 support current inputs like 4-20mA?

  This specific module targets voltage inputs (-10 to +10V). To process 4-20mA current signals, you would typically require a different module, such as the IC694ALG221, or use high-precision external shunt resistors.

• Can I use this module in an older Series 90-30 rack?

  No. The IC694 series specifically targets the PACSystems RX3i universal backplane. While it shares some visual similarities with the older IC693 series, it utilizes the advanced RX3i bus for higher throughput and diagnostics.

• How do I troubleshoot a specific channel?

  The module communicates diagnostics directly to the RX3i CPU. You can monitor individual channel health and over-range/under-range conditions through the programming software or by checking the status LEDs on the front faceplate
