GE IC670ALG230K Field Control Analog Input Module
Product Overview
The GE IC670ALG230K is a high-performance 8-channel analog input module designed for GE Fanuc’s Field Control Series, a cornerstone of industrial automation systems. As part of the IC670 Series, this module bridges the gap between analog field devices (e.g., pressure transmitters, flow meters) and digital control systems, converting 0–20 mA or 4–20 mA current signals into 12-bit digital data for PLCs or other host systems. Its single-ended input configuration and 5.0 µA resolution ensure precise data acquisition in critical processes, while 1500 VAC isolation safeguards against electrical noise and transient spikes.
The IC670ALG230K operates with a compatible Bus Interface Unit (BIU) such as the IC670GBI002 or IC697GBI102, which handles signal scaling and communication with the host. This modular design reduces panel space by integrating terminal blocks directly into the module, freeing up to 30% of cabinet space compared to traditional I/O systems 5. Its 24 VDC power supply supports both module operation and powering field devices, simplifying wiring in distributed control systems.
In automation workflows, the IC670ALG230K excels in applications requiring real-time monitoring of analog parameters, such as pressure in oil refineries, temperature in power plants, or flow rates in water treatment facilities. Its open-circuit detection and overrange fault protection minimize downtime by alerting technicians to wiring issues or sensor failures 16. Though part of a legacy series, the GE IC670ALG230K remains a trusted choice for retrofitting or maintaining industrial infrastructure, offering reliable performance in harsh environments (0°C to 60°C) with CE certification for safety compliance.

Main Features and Advantages
High-precision analog conversion:
The IC670ALG230K’s 12-bit resolution and 5.0 µA sensitivity enable accurate measurement of small signal variations, critical for applications like chemical dosing or turbine vibration monitoring. Its 60 µs conversion time ensures real-time data updates, reducing latency in closed-loop control systems.
Integrated fault detection:
Built-in diagnostics identify open circuits, overcurrent conditions, and signal overrange, providing actionable alerts to technicians. For example, if a pressure transmitter fails, the module flags the fault, allowing immediate replacement without system shutdown 16.
Space-saving design:
By eliminating the need for external terminal blocks, the IC670ALG230K streamlines panel layouts, ideal for compact control cabinets in packaging machinery or skid-mounted systems. Its DIN rail mounting further simplifies installation in confined spaces.
Rugged industrial durability:
Rated for 0°C to 60°C operation and protected against dust and moisture, the module withstands extreme conditions in oil rigs, steel mills, and wastewater treatment plants. Its 1500 VAC isolation ensures immunity to ground loops and voltage surges common in heavy industrial environments.
Flexible compatibility:
Works seamlessly with GE Fanuc’s Genius I/O Series and Series 90-30/70 PLCs, as well as third-party systems via the Genius Bus. This universality allows retrofitting legacy systems or integrating with modern control architectures without hardware replacements.
Low power consumption:
Drawing just 51 mA from the BIU power supply, the IC670ALG230K minimizes energy usage, making it suitable for remote or energy-constrained applications like solar farms or offshore platforms.
Application Areas
The GE IC670ALG230K is widely deployed in industries requiring precise analog signal management:
- Oil and Gas:
Monitors pressure and flow rates in pipelines, calibrates level transmitters in storage tanks, and interfaces with gas chromatographs for process analysis. Its fault detection capabilities prevent safety incidents caused by sensor malfunctions 13. - Power Generation:
Measures temperature and vibration in steam turbines, controls boiler feedwater flow, and integrates with SCADA systems for grid stability. Its high resolution ensures accurate load balancing in power plants 12. - Water and Wastewater:
Converts signals from pH sensors, dissolved oxygen meters, and sludge density transmitters, enabling closed-loop control of chemical dosing and filtration processes. Its compact design fits into decentralized pump station control panels 12. - Manufacturing:
Monitors conveyor belt tension, adjusts motor speed via VFDs, and verifies paint thickness in automotive assembly lines. Its real-time data output supports predictive maintenance strategies 16.
Specific applications include commissioning new process control systems, resolving intermittent sensor faults, and performing routine health checks on I/O modules during scheduled maintenance.

Installation and Maintenance
Pre-installation preparations:
Verify the IC670ALG230K is compatible with your BIU (e.g., IC670GBI002) and host system. Ensure the 24 VDC power supply meets the module’s requirements (18–30 VDC). Connect the module to the BIU using the IC670HHC005 interface cable, securing all connections to prevent vibration-induced dislodging. Configure input ranges (0–20 mA or 4–20 mA) via the BIU software, then power on the system to initialize communication.
Maintenance suggestions:
Clean the module’s vents quarterly to prevent dust accumulation, which can cause overheating. Inspect wiring connections for corrosion or loose terminals, particularly in humid environments. Replace the module if diagnostic LEDs indicate internal faults (e.g., constant red “FAULT” light). For long-term storage, keep the IC670ALG230K in a dry, temperature-controlled environment (10–30°C) to avoid component degradation. Calibrate the module annually using GE’s IC670ALG230 calibration tool to ensure accurate signal conversion.
