Multipurpose isolation type signal acquisition module with open circuit and short circuit detection function

The utility model relates to a multipurpose isolation type signal acquisition module with an open circuit and short circuit detection function. The multipurpose isolation type signal acquisition module is used for simultaneously realizing open circuit, short circuit and existence detection of various signals. Comprising an open circuit acquisition circuit, a short circuit acquisition circuit, a multipurpose signal acquisition circuit, a main control circuit, a display circuit, a communication circuit and upper computer software. The open-circuit acquisition circuit is used for detecting an open-circuit fault of the detected circuit; the short-circuit acquisition circuit is used for detecting a short-circuit fault of the detected circuit; the multipurpose signal acquisition circuit is used for detecting whether the detected circuit has an output signal or not; the three acquisition circuits transmit detection results to the main control circuit; the main control circuit records a detection result and sends the
