ABB SDCS-CON-2A 3ADT309600R0002 Control Board

ABB SDCS-CON-2A 3ADT309600R0002 control board is based on the 80186EM microprocessor and the ASIC circuit DC94L01. Programs such as the system and parameter values ​​are stored in the Flash PROM D33, application functions and parameter values ​​are saved in the Flash PROM D35, and fault and alarm information are stored in the static RAM circuit. It is powered by a 1F backup capacitor and can be charged for about 30 minutes. It can last for at least 8 hours and usually for several days.

Fuctions & Features

• Storage function: System and parameter programs are stored in Flash PROM D33, and different programs can be downloaded directly; application functions and parameter values ​​are stored in Flash PROM D35; fault and alarm information, running time, etc. are stored in static RAM circuit.

• ASIC function:

1. Communication function: Communicate with control panel and field exciter through RS 485.
2. Measurement function: Complete the relevant measurement work of DCS500.
3. Monitoring function: With watchdog function to ensure the normal operation of control board program.
4. Conversion control: A/D and D/A conversion control is realized.
5. Pulse generation: Responsible for the generation of thyristor trigger pulses.

• Watchdog function: If the internal watchdog of the control board is triggered, it will disable the writing to FPROM, reset and disable the thyristor trigger control, force the digital output to a low level, and reset the programmable analog output to 0V.
