Deep Sea Electronics DSE103 Speed Switch Control

Deep Sea Electronics DSE103 MKII Speed Switch Control Module monitors the speed of an engine by detecting pulses from a magnetic pick-up device or alternative output.
Independent relays can be operated at different speed settings. The relays can be set between 0-400% of the engines rated running speed. This flexibility allows the module to be used for multiple application types including under/over speed and crank disconnect.
