General Electric IC694ALG223 Input Module

The GE PACSystems IC694ALG223 serves as a high-density solution for analog signal acquisition. This module integrates seamlessly into RX3i and Series 90-30 PLC environments. It provides sixteen single-ended channels for monitoring industrial current loops.

Operational Overview

This unit converts external analog signals into digital data for the controller. It supports multiple current ranges including 0-20 mA and 4-20 mA. Additionally, an enhanced 4-20 mA mode offers superior error detection. The module uses a 12-bit converter to ensure high-fidelity data processing.

Technical Capabilities

• High Resolution: Delivers precise measurements with increments as small as 4 μA.
• Rapid Updates: Achieves a fast 13 ms conversion rate for all active channels.
• Signal Integrity: Features common-mode rejection exceeding 70 dB to filter electrical noise.
• Fault Monitoring: Detects open-wire conditions specifically in the enhanced 4-20 mA range.
• Power Management: Monitors external loop power to ensure constant system availability.
• Calibration: Every unit undergoes factory calibration for immediate field deployment.
