GE Fanuc IC694ALG233 Analog Current Input Module – Product Description

Product Overview

The GE Fanuc IC694ALG233 is a high-density current input module designed for accurate measurement in demanding industrial environments. It converts real-world analog signals from sensors and transmitters into stable digital data for RX3i PLC processing. Moreover, engineers rely on this module when consistent performance and predictable system behavior are essential for large control architectures.

Its 16-channel structure offers excellent scalability for process plants and factory systems that require dense measurement points. In addition, the module supports multiple current ranges, which gives field technicians the flexibility to standardize instrumentation without adding additional hardware. Therefore, it becomes a reliable choice for facilities upgrading legacy analog systems to modern PACSystems platforms.
