BHEL 69203IA2AA1A BHEL Control PCB Board, Turbine Control Card

Overview The BHEL 69203IA2AA1A is a BHEL original printed circuit board for turbine control automation systems. It is used for signal conditioning, data acquisition and interlock logic processing for power plant turbine control systems, widely stocked as spare for thermal power station BHEL control panels.

Features This control board adopts standard backplane bus interface, with on-board diagnostic LED indicators and signal isolation circuit. The 69203IA2AA1A supports zero/span calibration on site, and can be used for retrofitting and replacement of existing BHEL turbine automation cabinets. It is a legacy spare part for Indian power plant control systems.

Specs Model: 69203IA2AA1A Series: BHEL Turbine Control Type: Turbine control PCB board Mounting: Chassis backplane plug-in Protection class: IP20 Certifications: CE Product status: obsolete power automation spare

Principle The 69203IA2AA1A collects analog and discrete field signals from turbine sensors, converts signals into digital data, transmits data to the main controller, and executes protection interlock commands. It reports device failure and signal fault events.

Applications The 69203IA2AA1A is widely deployed in thermal power plants and BHEL turbine control cabinets. It is used for monitoring and control of steam turbine auxiliary measurement and protection signals.
