The invention provides an emergency trip control module of a steam turbine, and relates to the technical field of steam turbine control. The emergency trip control module comprises a pressure transmitter, a stop valve, a high-pressure elbow, a seamless steel pipe and a DCS cabinet, wherein the end, close to the stop valve, of the seamless steel pipe is connected with the high-pressure elbow, the end, far away from the seamless steel pipe, of the high-pressure elbow is connected with the stop valve through a pipeline, the end, away from the high-pressure elbow, of the stop valve is connected with the pressure transmitter, and the pressure transmitter is connected with the DCS cabinet through a cable. According to the emergency trip control module, the increased pressure transmitter can record ASP oil pressure fluctuation trend through a DCS system to facilitate the analysis after an ASP switch makes an alarm, and when the switch and a pressure representation value are deviated, the pressure transmitter can ser
