GE Fanuc IC697ALG230 Analog Input Base Conversion Module

Technical Specifications

The GE Fanuc IC697ALG230 serves as a primary analog data acquisition interface for the Series 90-70 PLC range. This module converts field-level analog signals into digital values for the central processor. It provides eight differential input channels with high accuracy and noise rejection. Furthermore, this base module allows for significant hardware expansion via secondary modules. It specifically supports industrial voltage ranges and standard current loops like 4-20 mA. This component is essential for monitoring temperature, pressure, and flow in large-scale automation. Its modular design ensures long-term scalability for complex control architectures.

Expansion and System Scalability

The IC697ALG230 acts as a foundation for much larger input systems. Users can connect up to seven expansion modules to this base unit. Specifically, it works with IC697ALG440 voltage expanders and IC697ALG441 current expanders. This configuration allows a single slot to eventually manage up to 120 analog channels. Furthermore, the module integrates easily with existing Series 90-70 racks and power supplies. Programming occurs through standard MS-DOS or Windows-based configuration software. Consequently, engineers can define unique parameters for each channel independently. This flexibility simplifies the management of diverse sensor types in one system.

Installation and Maintenance

The hardware features a removable 40-terminal connector block for simplified field wiring. This design allows for module replacement without disconnecting individual field wires. Furthermore, the unit fits into a single slot of any IC697 PLC backplane. The module operates reliably in temperatures ranging from 0°C to 60°C. It complies with international safety standards to ensure workplace security. Because it uses a rugged mechanical housing, it withstands vibration in factory settings. This module remains a dependable choice for legacy system support and modern industrial upgrades.
