Description
ABB CMA121 SYNPOL D Extended Controller Panel Unit
Product Overview
ABB CMA121 is an extended controller panel unit for SYNPOL D system, usually combined with CMA120 basic panel to expand human-machine interaction functions. This panel adds more parameter display channels and operation keys, monitors more operating data of generator sets synchronously, and supports auxiliary operation commands such as grid connection and voltage regulation. It is widely used in marine power stations, diesel generator synchronization and excitation control cabinets, serving as supporting HMI spare parts for SYNPOL D power station control systems.
