This utility model provides an engine speed signal isolation and branching module, belonging to the field of engine testing technology. This module solves the problems of signal interference and signal degradation when testing engine speed, phase, and other signals. The module's signal input unit connects the sensor signal terminal to the input terminal of the signal isolation unit. The output terminal of the signal isolation unit connects to the input terminals of the signal inverting unit and the signal output unit. The output terminal of the signal inverting unit connects to the input terminal of the signal output unit, and the output terminal of the signal output unit connects to the input terminal of the testing equipment. The isolation power supply unit converts the sensor power supply into an isolated power supply output. This module has the function of isolating and branching the speed sensor output signal, eliminating signal interference, preventing signal degradation, and simultaneously outputting in-phase and in-phase signals. The module uses a multiplexing method internally for high reliability, and adopts a non-destructive connection method to avoid damaging the wiring harness, thus improving work efficiency.
