Product Details

ABB CMA136 3DDE300416 is a communication and relay terminal board for ABB Synpol D generator control and protection systems. The communication and relay terminal board provides multiple serial interface ports to realize data exchange between the main control unit, operator panel and external monitoring equipment, and also handles relay signal routing and terminal connection for generator interlock signals. This ABB CMA136 board integrates multiple DB9 serial connectors and field wiring terminals, converting internal system bus signals into standard serial communication signals for external connection. The Synpol D serial interface unit adopts galvanic isolation design to suppress electromagnetic interference in power plant cabinets and protect internal control circuits. It has built-in self-diagnostic function to monitor communication link status and terminal wiring faults, and feed back alarm information to the main controller once communication interruption or wiring failure occurs. It works together with CMA131 operator panel, CMA132 relay board and other modules to complete generator monitoring, excitation regulation and power protection functions. Widely used in thermal power, hydropower and marine generator control cabinets, it is essential spare part for Synpol D system maintenance and renovation. DIN rail mounting structure enables convenient installation and quick field replacement.
