GE IC693ALG390 Analog Output Voltage Module – Series 90-30 PLC
When an analog output module fails on the plant floor, the consequences are immediate and costly: actuators freeze at their last commanded position, control valves lose their setpoint signal, and variable-speed drives revert to manual override. Production lines halt, process engineers scramble, and every minute of downtime translates directly into lost revenue. The GE IC693ALG390 is the precision analog output voltage module engineered to prevent exactly this scenario — delivering stable, accurate voltage signals that keep your process control loops running without interruption.
Within GE’s iconic Series 90-30 PLC platform, the IC693ALG390 occupies a critical role as the primary 8-channel analog voltage output module. The Series 90-30 system has been deployed across tens of thousands of industrial facilities worldwide — from petrochemical refineries in the Middle East to automotive assembly plants in Europe and Asia — and the IC693ALG390 remains one of its most specified analog output solutions. Its combination of multi-channel density, dual voltage range support, and seamless integration with the Series 90-30 backplane makes it an enduring choice for both new installations and legacy system maintenance.
