Collection: GE Series 90-20 / 90-30 / 90-70

The GE Series 90-20, 90-30, and 90-70 PLCs were key components in industrial automation, now considered legacy products by GE (now Emerson).

• 90-20: A compact, cost-effective PLC for small applications with basic I/O and programming capabilities.
• 90-30: A versatile mid-range PLC offering modular design, a wide range of I/O, and advanced programming features for medium-sized tasks.
• 90-70: The most powerful PLC in the series, designed for large, complex applications with high processing power, large memory, and extensive communication options.

Each model served different scales of automation, with the 90-20 being the most cost-effective and the 90-70 designed for the most demanding, large-scale applications.
