This product selection AX series safety relays for optimum design, in view of the turn point machine characteristics, realized speed the construction of the rail circuit training, joint the actual, the application of the flexible, high reliability, is the rail transit kind professional training for electrical device of choice.

Electric turn point machine is rail control system of actuators, and the matching speed rail circuit mainly divided into three parts, namely indoor rail control circuit, rail action circuit and rail said circuit, the five wire circuits, indoor and outdoor contact with 5 lines of root cable named respectively X1 to X5.

Along with our country electrified railway and the rapid development of urban rail traffic, to adapt to the need for speed, from introduces the equipment and technology, digesting modified from the ac regulated quickly replaced early point machine of the type of regulated dc point machine, and the domestic main lines of the application type turn point machine.
