Product Details

ABB CMA132 3DDE300412 is a generator relay terminal board for ABB Synpol D generator control and protection systems. The generator relay terminal board handles digital and relay signal routing, terminal isolation and output drive for generator protection interlock signals. This ABB CMA132 board collects field status signals and transmits relay trip and interlock commands from the main control unit to on-site switchgear and auxiliary equipment. The Synpol D control terminal unit adopts galvanic isolation design to prevent external surge signals from damaging the main control hardware and improve system stability in power plant environments. It has built-in self-diagnostic function to monitor terminal wiring and internal circuit status, and output fault alarm signals for fast troubleshooting. It works cooperatively with CMA131 operator panel and other Synpol D modules to complete generator monitoring, excitation control and protection functions. Widely used in thermal power and hydropower generator control cabinets, it is an essential spare part for power system maintenance and renovation. Rack plug-in structure enables convenient installation and quick field replacement.
