CS.JH-SX series D/A converter is installed in driver’s cabin. It is used specially for connecting DF16 sensor with ENG, EGS, EGZ series single/double speedometer. It consists of DC/DC power board, BWA6 F/I board and BI6 mileage frequency divider board. It converts the frequency signal of the sensor into a linear current of 0-20mA or 4-20mA. ENG, EZG, EGS and EGZ speedometers display the locomotive running speed (when there is one engine and two speedometers, speedometer I and speedometer II are used in series). BI6 board carries out mileage frequency division according to the average wheel diameter, drives the speedometer, and implements mileage accumulation. It has characteristics such as simple and reliable, good interchangeability and so on. It can be used in various types of locomotives in domestic and aboard.
