Description
GE Fanuc IC670ALG310-JA Analog Output Module
1. Product Description
The GE Fanuc IC670ALG310-JA is a high-performance analog output module designed for industrial automation systems, part of the Genius Field Control and RX7i PACSystem families. Its core function is converting digital signals into precise analog voltage/current outputs (e.g., -10V to +10V voltage or 0–20.48mA current), making it ideal for controlling valves, motors, and actuators. With 8 isolated channels (2 groups of 4), it offers robust interference protection and flexible scaling. The -JA suffix denotes factory-calibrated voltage-source configuration. The module integrates seamlessly with GE’s control systems, delivering reliability in harsh industrial environments.

3. Advantages and Features
- Isolated Channel Design: Two isolated groups of 4 channels minimize ground loop interference.
- Flexible Configuration: User-configurable voltage/current outputs per channel, with 3 predefined scaling options + 1 custom setting.
- Diagnostic Capabilities: Real-time fault detection (over/under range, open circuit, power loss) and alarm triggers for proactive maintenance.
- Industrial Ruggedness: Wide temperature range (-20°C to +60°C) and compact design for harsh environments.
- Field Calibration: Flash memory stores calibration data for easy reconfiguration or factory reset.
4. Application Fields and Use Cases
Industries: Manufacturing, energy, chemical processing, water treatment.
Scenarios: Motor speed control, valve positioning, closed-loop temperature/pressure regulation.
Case Study: A chemical plant used the IC670ALG310-JA to control reactor pressure valves. Its 14-bit resolution and fast response (1.5ms) ensured precise pressure regulation, reducing downtime by 15% compared to legacy systems.

6. Selection Recommendations
- Compatibility: Ensure compatibility with Genius Field Bus Rev 2.0+ and GE’s I/O systems (e.g., RX3i).
- Environment: Choose based on temperature (-20°C to +60°C) and vibration requirements.
- Budget: Balance channel count (8 channels) and features (calibration, isolation) against cost.
7. Precautions
-
Power Stability: Use a stable 18–30V DC external power supply to avoid output fluctuations.
-
Wiring: Use shielded cables for analog signals; verify terminal block polarity.
-
Calibration: Perform annual checks; store calibration data in the module’s flash memory.
-
Hot Swap: Ensure proper grounding when replacing modules in live systems.
