ABB CMA150 (3DDE300410) SYNPOL D Analog Input Board

Product Description

The ABB CMA150 (3DDE300410) is an analog signal acquisition board for the ABB SYNPOL D generator protection and control system. It collects AC voltage, AC current and other analog measurement signals from generator instrument transformers, converts them into digital data for the main control board CMA127 to calculate electrical parameters and execute protection logic. It works with CMA127, CMA123 and other modules to complete generator monitoring and protection functions.
