GE IC694ALG222 Product Specification
Product Overview
The GE IC694ALG222 is a high-precision analog input module designed for GE’s RX3i PAC (Programmable Automation Controller) system. It converts real-world analog signals (e.g., voltage) into digital data for processing by PLCs, making it essential for monitoring and controlling industrial processes. With support for 16 single-ended or 8 differential input channels, this module adapts to diverse applications, from factory automation to power generation.
Rated for 0–10 VDC (unipolar) and -10–+10 VDC (bipolar) inputs, the GE IC694ALG222 offers a resolution of 2.5 mV (0–10 VDC) and 5 mV (-10–+10 VDC) . It processes signals with ±0.25% full-scale accuracy at 25°C and maintains ±0.5% accuracy across the operating temperature range (0°C to 60°C) . The module’s update rate is 6 milliseconds for single-ended channels and 3 milliseconds for differential channels, ensuring real-time responsiveness in critical systems like turbine control or chemical dosing.
Physically compact (263 × 58 × 28 mm) and lightweight (0.43 kg), the GE IC694ALG222 integrates seamlessly with RX3i racks (e.g., IC694CHS790) and requires an external 24 VDC power supply connected via the TB1 terminal block . Its field-to-backplane isolation of 250 VAC (continuous) and 1500 VAC (1-minute surge) safeguards against voltage spikes, while CE and UL certifications ensure compliance with global safety standards .

IC694ALG222
Main Features and Advantages
Dual Wiring Configurations: The GE IC694ALG222 supports both single-ended and differential wiring. Single-ended mode is ideal for cost-effective applications with low electromagnetic interference (EMI), while differential mode enhances noise resistance in high-interference environments like steel mills or mining operations .
High Precision and Speed: With 12-bit resolution and fast update rates, the module ensures accurate real-time data acquisition. Its ±0.25% accuracy at 25°C minimizes measurement errors, critical for processes like pharmaceutical mixing or oil refining where precision directly impacts product quality .
Robust Design: Built to withstand industrial conditions, the GE IC694ALG222 operates reliably in extreme temperatures and humidity. Its isolation features protect against voltage surges, reducing downtime caused by equipment failures .
Flexible Power Supply: While requiring an external 24 VDC power source, the module efficiently distributes energy, with low power consumption ensuring compatibility with standard industrial power systems .
Diagnostic Capabilities: LED indicators for power (P/S) and module status (OK) provide quick visual checks, simplifying maintenance and troubleshooting. The module’s RS485 interface (via the RX3i backplane) enables remote monitoring of input values and fault conditions .
