GE IS215WEMAH1A (WEMA+BPSP Integrated I/O Main Control Board | Mark VIe Wind Special)

GE IS215WEMAH1A (WEMA+BPSP Integrated I/O Main Control Board | Mark VIe Wind Special)

1、 Product basic information
Brand: GE General Motors | Series: Mark VIe Wind (Wind Power Specific Control System) | Full Name: WEMA+BPSP Integrated Analog I/O Assembly Board
IS215=assembly version (equipped with sub card BPPS); IS200WEMAH is a bare substrate model
The original factory has stopped production, only new inventory/dismantled spare parts are circulating, and the 1.5MW wind power model comes with standard board cards for the cabin cabinet
core positioning
The main control of the wind turbine cabin collects analog signals and uses a local logic control board to collect cabin temperature, vibration, wind speed, pitch hydraulic pressure, and generator winding temperature measurement signals. It outputs 4-20mA control pitch, hydraulic valve, and cooling fan, and is used in conjunction with the IS210AEPSG power supply and IS210AEBIH communication card on the same frame.

2、 Key hardware parameters
table
Project parameter specifications
Signal channel multi-channel RTD platinum resistance temperature measurement, 4-20mA/0-10V analog input; 0-20mA analog output, relay switch output
Backplane bus VME bus, rack backplane is powered by AEPS power card DC5V
Simulation accuracy ± 0.1% FS full scale, input circuit isolated 2500VAC anti-interference
Working environment -30 ℃~+65 ℃; Storage -40 ℃~+85 ℃, full board with three anti coating (moisture-proof, salt spray, outdoor wind power environment)
External dimensions 264mm × 213mm, standard VME card specification, rack rail insertion and installation
Net weight of the board is approximately 1.35kg
Communication board with Ethernet+RS485, Modbus TCP/RTU, docking with upper level ControlST software for debugging and fault recording
3、 Model Swap and Derivative Versions
IS215WEMAH1A: B upgraded version, fully compatible with hardware pins, can directly replace IS215WEMAH1A (the most commonly used replacement spare part on the market)
IS200WEMAH1AEA: Bare substrate (without BPPS sub board), BPPS small board needs to be installed to be equivalent to IS215WEMAH1A function
Same series supporting boards: IS210AEPSG1B (rack power supply), IS210AEBIH1B (bridge communication card), IS210AEDBH (digital board)
4、 Application scenarios
GE 1.5MW doubly fed onshore wind turbine generator set (main): equipped with a main control cabinet in the engine room, with full acquisition and control of the pitch system and generator status;
Small gas turbine, distributed self owned power plant Mark VIe control system BOP auxiliary control acquisition;
The photovoltaic power station’s energy storage inverter is equipped with a DCS signal acquisition cabinet.
5、 Key points of malfunction and replacement
Fault symptoms: abnormal temperature measurement, analog output drift, network port disconnection. Priority should be given to replacing this card;
Replacement priority order: IS215WEMAH1BA>Original A-version>Refurbished parts, firmware version can be refreshed online through ControlST for compatibility.
