Tach Signal Voltage at Carol Swenson blog

Tach Signal Voltage. If your tach is a powered variety, (needs 12 volts to operate in addition to the tach signal), check for voltage at the tach. To determine which standard a motherboard uses for the tach signal, check the voltage across the pins on the motherboard fan socket with an oscilloscope; Logically, this suggests that there is a minimum voltage below which the tach signal generation. The tach signal indicates whether the fan is running and its rate of speed. The tach signal, when driven by a dc voltage, has a square. The main concern when connecting the tach to any instrumentation is the inductive ringup/flyback voltage when the transistor shuts off (and the plugs fire). The main concern when connecting the tach to any instrumentation is the inductive ringup/flyback voltage when the transistor. The tach signal is valid during phases when the input power is 12 v. Tach is an interrupt to gnd (a momentary high z state) when the field direction through the sensing region of the hall effect and coil control device.
