GE IC694ALG442 Analog I/O Module
Product Overview
The GE IC694ALG442 is a mixed analog input/output module designed for GE’s RX3i PACSystems, a robust platform used in industrial automation. This module plays a crucial role in industrial control systems by converting real-world analog signals, such as temperature and pressure, into digital data that can be processed by a PLC. It also sends digital commands back to the field to control devices like valves and motors. As part of the IC694 Series, the GE IC694ALG442 integrates seamlessly with RX3i backplanes, such as the IC694CHS790, and works alongside CPUs like the IC694CPU331 to enable precise automation.
The GE IC694ALG442 features 4 analog input channels and 2 analog output channels, offering a balanced solution for systems requiring both signal acquisition and control. The input channels support various signal types, including ±10 V DC, ±5 V DC, ±1 V DC, ±0.5 V DC, ±0.2 V DC, and 4–20 mA, while the output channels can provide ±10 V DC or 4–20 mA signals. Each channel offers 16-bit resolution, ensuring high precision in both measurement and control. The module also includes optical isolation (250 V AC continuous) to protect against electrical noise, a critical feature in industrial environments with heavy machinery.
Designed for flexibility, the GE IC694ALG442 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.

High precision and accuracy: The 16-bit resolution and ±0.05% input accuracy ensure precise measurement of critical parameters, such as pressure in hydraulic systems or flow rates in chemical processes. The ±0.1% output accuracy enables precise control of devices like servo motors or variable frequency drives.
Robust isolation: Optical isolation protects the module from electrical noise and ground loops, ensuring reliable operation in noisy industrial environments. This feature is particularly important in facilities with large motors or high-power equipment.
Easy configuration and integration: The module can be configured using GE’s Proficy Machine Edition software, which provides a user-friendly interface for setting input/output ranges, scaling, and filtering. It integrates seamlessly with other RX3i modules, simplifying system integration and maintenance.
Installation and maintenance
Pre-installation preparations: Verify compatibility with your RX3i backplane (e.g., IC694CHS790) and ensure an available I/O slot. Power off the system and disconnect all power sources. Align the IC694ALG442 with the slot and push firmly until it clicks into place. Connect the +24 V DC power cable to the backplane’s TB1 terminal block, ensuring proper polarity. Use shielded twisted-pair cables for analog signals, grounding the shield to minimize noise.
Maintenance suggestions: Inspect the IC694ALG442 quarterly for loose connections or physical damage. Clean dust from vents using a dry cloth to prevent overheating. If the module’s status LED indicates a fault, power off the system and reseat the module. For persistent issues, replace it with a spare from your inventory. Store spare modules in a dry, cool environment (10–30°C) to maintain their integrity. Regularly calibrate the module using GE’s Proficy Machine Edition software to ensure accuracy over time.
