Product Introduction
The GE IC693ALG391 is a 2-channel analog current output module designed for the GE Fanuc Series 90-30 programmable logic controller (PLC) family. It is specifically engineered to deliver reliable current signals for field device control in process automation systems. Each channel is capable of outputting signals in the range of 4 to 20 mA, which is the industry standard for analog current control.
The module is isolated from the backplane and includes diagnostic features that help monitor system integrity. Its compact design, high accuracy, and compatibility with Series 90-30 racks make it ideal for both retrofit projects and new control system installations.
