SD8421 Pulse Shaper and Divider.
The SD8421 pulse shaper and amplifier was designed for Veeder-Root, Kienzle and Motometer Tachographs requiring a dual signal asynchronous pulse. The SD8421 can also divide the speed signal by a factor of 2, 4, or 8, as required, by simply moving a shunt.
SD8421 converts a sine, square or triangular signal to a square wave signal at host voltage.
Ideal for getting out of range speedometers and tachometers within range.
Works equally well on speed or RPM signals.
