XIonghua - Model XHPS-20P - Water Supply and Drainage Controller
XHST/20P the controller is designed for water supply and drainage . It is small in size and visual to display,easy to operate. With professional software knowledge, the user can modify the parameter directly to adapt to the different requirements of the work set. 5 input points ; high level,median level ,low level and 2 fault signal 4 output points : control the pump and output the operating signal, the contacts load of the relay is 250V2A The program of the controller has the automatic removing rust function, the rotation working time of the pumps can be changed,automatically switch to another pump as one pump breakdown,level signal delay function . The ordinary control boxes have no these functions Memory storage (10years)/mechanical life The liquid level detection adopts the low voltage sampling, which avoid the oxidation of the strong voltage signal to level switch contacts. This can prolong the using life of the float and ensure the reliable of the whole equipment.
