GE IC693ALG391F Analog Current Output Module
Product Overview
The GE IC693ALG391F is a high-precision 2-channel analog current output module designed for GE Fanuc’s Series 90-30 PLC platform, now under Emerson Automation Solutions. As part of the IC693 Series, this module converts 12-bit digital signals into analog current outputs, enabling precise control of actuators, valves, and variable-speed drives in industrial automation systems. With support for 0–20 mA and 4–20 mA output ranges, the IC693ALG391F is ideal for applications requiring seamless integration with process instruments, such as flow meters, pressure transducers, and temperature controllers.
Featuring a 12-bit resolution (5 µA per bit for 0–20 mA), the IC693ALG391F delivers an absolute accuracy of ±8 µA at 25°C for 0–20 mA outputs and ±0.1% of full scale for 4–20 mA outputs, ensuring reliable performance in critical control loops 715. Its 5 ms update rate ensures real-time responsiveness, while 1,500 V RMS isolation between field and logic sides mitigates electromagnetic interference (EMI) in high-noise environments like manufacturing plants or oil refineries . The module incorporates MOV (Metal Oxide Varistor) surge protection on high-power terminals, safeguarding against voltage spikes caused by inductive loads or transient electrical noise 17.
In automation systems, the IC693ALG391F integrates with Series 90-30 CPUs (e.g., IC693CPU340, IC693CPU364) and Genius Bus Interface Units (BIUs) to provide analog control signals for process optimization. Its compact DIN rail-mount design (125 mm × 48 mm × 45 mm) and lightweight construction (0.35 kg) simplify installation in crowded control panels, while a flame-retardant ABS housing ensures durability in temperatures ranging from 0°C to 60°C and 95% non-condensing humidity . Though discontinued by GE, the IC693ALG391F remains critical for legacy systems, offering cost-effective scalability where upgrading to newer platforms is impractical. By combining high-resolution signal conditioning, rugged isolation, and deep integration with Series 90-30 components, this module enhances system precision and reduces downtime in mission-critical operations.

Maintenance suggestions:
Perform quarterly visual inspections to check for loose connections or physical damage, retightening terminals to 5 lb-in torque as needed. Test surge protection components annually using a multimeter to ensure MOVs are functional. Replace the module every 7–10 years (or sooner if physical damage is detected) to maintain signal integrity. Store spare IC693ALG391F modules in anti-static packaging at 10–30°C with <60% humidity, testing functionality biannually .
