Overview
The ABB 720087 (also designated AE 25020 K3) is a turbine controller card module engineered for integration into ABB STAL turbine control systems. This PLC processor card provides precise control and monitoring capabilities for steam turbines, gas turbines, and hydro turbine applications. Built on proven ABB turbine automation technology, the 720087 module addresses critical turbine control requirements including valve positioning, speed detection, protection logic, and supervisory control.
Key Features
- Purpose-built card module for ABB STAL turbine control platforms
- Supports valve positioning, speed detection, and turbine protection functions
- Din-rail compatible mounting in standard module mounting units
- Configured via PC-based software applications with hardwired I/O signal interface
- Proven technology deployed globally in steam, gas, and hydro turbine installations
- Integrated single-vendor solution for comprehensive turbine automation
Technical Specifications
The ABB 720087 module is designed as a single printed circuit board that occupies one slot in a standard module mounting unit (MMU). Configuration is managed through onboard jumpers, switches, and DIP settings on both the circuit board and termination unit. The module interfaces with field devices via a cable-connected termination unit.
Typical Applications
- Steam turbine throttle and control valve positioning
- Gas turbine fuel valve and inlet guide vane control
- Hydro turbine speed and load regulation
- Turbine protection and overspeed prevention
- Supervisory control and condition monitoring
- Integration into ABB DCS platforms and SCADA systems
