PIB101C 3BD91299‑B ALSTOM T3000 Analog Interface Module

Product Description
3BD91299‑B (full model PIB101C-3BD91299-B) is Alstom T3000 turbine control system analog input/output interface board. It serves as the signal interface between T3000 controller and field transmitters, actuators and sensors. It collects analog process signals and outputs analog control commands for turbine valve position regulation. This PCB board is widely used in steam/gas turbine control cabinets of thermal power and combined cycle power plants. The T3000 platform is legacy Alstom turbine control system, now under GE Vernova.

Key Features

• 8 analog input channels and 6 analog output channels, 4-20mA / ±10V signal type
• Dual redundant channel design, fault diagnosis for open circuit, short circuit and overrange
• High precision signal sampling for pressure, temperature, vibration and valve position feedback
• Backplane communication interface to exchange data with T3000 CPU rack
• Onboard watchdog and self-test, LED status indicators for channel and module health
• Rack-mounted PCB card, designed for turbine cabinet with high vibration and temperature resistance
• Original production discontinued; only surplus new old stock and refurbished spare parts available for power plant maintenance

Application Scenarios

• Alstom / GE T3000 steam turbine and gas turbine control systems
• Combined cycle power plant, thermal power generation turbine control cabinet
• Boiler and turbine analog signal acquisition and valve control loops
• Power plant unit retrofit, spare replacement for legacy T3000 control system

FAQ

Q: What system does PIB101C 3BD91299-B belong to?
A: It belongs to Alstom T3000 turbine control system, used for turbine analog I/O signal processing.

Q: What signals does this module process?
A: 4-20mA analog input from field sensors, analog output for control valve drive command.

Q: Is this module hot-swappable?
A: Not hot swap. Rack power needs to be isolated before removing and replacing the board.
