Description

The 9191-30390 (complete catalog number 919130390) is an industrial control circuit board manufactured by ABB, serving dual roles as both a system power module and a control interface board-2-4. This versatile component is primarily associated with ABB’s Advant OCS and Advant 800xA distributed control systems, as well as K-TRON loss-in-weight feeder applications-1-2-8.

Engineered for harsh industrial environments, the 9191-30390 integrates power conversion, signal processing, and communication capabilities into a single compact board. Its wide-range 100-240V AC/DC input, robust 4.2A overload capacity, and extended operating temperature range make it suitable for demanding applications in chemical processing, power generation, and material handling-4-13.

Application Scenarios

In a chemical plant running an ABB Advant 800xA DCS, the 9191-30390 resides in the control cabinet, converting incoming AC power into stable DC for system components while handling communication tasks between the controller and field devices. When one of these boards failed after 15 years of service, the plant faced a critical situation: without this module, an entire reactor control loop lost power and communication. Sourcing a tested 9191-30390 replacement restored the system within hours, avoiding an estimated $150,000 in production loss.

For material handling operations using K-TRON loss-in-weight feeders, the 9191-30390 serves as the power and control core-1-4. Its patented screw speed modulation algorithm improves feeder accuracy at low rates (below 60 rpm) by predicting periodic pulsation and compensating in real time-1. This capability directly addresses a long-standing pain point in precision feeding applications where material flow inconsistency can compromise product quality. The module’s integrated refill control simplifies feeder hopper management, reducing operator intervention-1.

System integrators maintaining legacy ABB installations value the 9191-30390 for its ability to bridge older Advant and Bailey INFI90 systems with modern communication protocols-2-13. The RS-485 interface with Modbus support allows these vintage DCS platforms to exchange data with contemporary HMIs and SCADA systems, extending the useful life of existing infrastructure while deferring costly full-scale upgrades.
