GE IC694ALG233 Analog Input Module
Product Overview
The GE IC694ALG233 is a 16-channel analog input module designed for GE’s RX3i PACSystems, a robust platform widely used in industrial automation. This module converts real-world analog signals—such as temperature, pressure, and flow—into digital data that PLCs can process. It plays a crucial role in monitoring and controlling complex industrial processes, making it ideal for applications requiring high-density analog input capabilities. As part of the IC694 Series, the GE IC694ALG233 integrates seamlessly with RX3i backplanes (e.g., IC694CHS790) and works alongside CPUs like the IC694CPU331 to enable precise automation.
The GE IC694ALG233 supports a variety of input ranges, including ±10 V DC, ±5 V DC, ±1 V DC, ±0.5 V DC, ±0.2 V DC, and 4–20 mA. Each channel offers 16-bit resolution and ±0.05% accuracy, ensuring highly precise measurements. The module features optical isolation (250 V AC continuous) to protect against electrical noise and ground loops, a critical feature in industrial environments with heavy machinery. Its scanning rate of 10 milliseconds allows real-time data acquisition, enabling quick responses to process changes.
Designed for flexibility and scalability, the GE IC694ALG233 can be installed in any I/O slot of an RX3i rack. It requires an external +24 V DC power supply (connected via the backplane’s TB1 terminal block) and supports configuration through GE’s Proficy Machine Edition software. This module is particularly useful for retrofitting legacy systems, as it maintains compatibility with earlier GE platforms while leveraging the RX3i’s advanced communication capabilities.
