GE IC693ALG391 Product Specification
Product Overview
The GE IC693ALG391 is a 2-channel analog current output module engineered for GE Fanuc Series 90-30 PLC systems, designed to convert digital signals into precise analog current outputs for industrial automation control. With support for 0–20 mA and 4–20 mA output ranges, this module delivers 12-bit resolution (5 µA per bit for 0–20 mA; 4 µA per bit for 4–20 mA) and ±0.1% full-scale accuracy at 25°C, ensuring reliable performance in applications such as process control, valve regulation, and sensor actuation .
Featuring a 5 ms update rate for both channels, the GE IC693ALG391 enables real-time adjustments in dynamic systems, while its 1500 VDC isolation between field and logic sides safeguards against electrical noise and surges . The module accepts ±24 VDC power from the backplane or an external user-supplied source, with a low power consumption of 30 mA from +5 VDC and 215 mA from +24 VDC . Its hot-swap capability allows maintenance without system downtime, reducing operational disruptions in continuous production environments like oil refineries or pharmaceutical plants .
Constructed with a flame-retardant ABS casing, the GE IC693ALG391 withstands harsh conditions (0°C to +60°C operating temperature, 5–95% non-condensing humidity) and integrates seamlessly into IC693CHS397 and IC693CHS391 racks via a snap-fit mechanism . The module’s terminal block connectors support easy wiring, while LED indicators (Module OK, Power OK) provide real-time status monitoring for efficient diagnostics .
