Telegraph Sounder Driver. This board takes a logic input and drives up to 10A (momentary) via an N Channel FET. Internal clamp diode provided. The Sounder Driver was designed to drive low resistance (< 24 ohm) telegraph sounder coils with our Morse Code Buzzer Controller, but it can be used to drive any high current load. A logic low input yields a ground on the output.
