Speed Signal Interface

The SN74Z has the following features when used as a Speedometer interface. Input Source Options : Three wire pulse signal generator input source. Built-in Vehicle Speed Sensor (VSS) input source. Work with most Tremec transmissions, Later model 700R4’s. Typically a sine wave signal Two wire pulse signal generator input source Classic Instruments SN96 or SN95 Typically a sine wave signal One wire ECM signals input source Typically a 5 volt square wave Output. The output can be selectable between either 8000 pulse per mile or 16000 pulse per mile Outputs a 12V square wave, 50% duty cycle 8000 pulse per mile cruise control output. Additional Benefits: Three different calibration options Instant: drive 30 MPH and press the calibration button Real-Time: press and the hold the calibration button to match the speedometer reading to the actual vehicle speed Marked Mile: Drive a measured mile to calibrate the speedometer Input signal can range from 2000-200,000 pulses per mile State of the art signal averaging software that ensures smooth pointer operation, even in fluctuating signal conditions. Noise-reducing, filtered power output for powered speedometer signal generators.
