XHST-10/20P control for water supply and drainage equipment specially designed controller, small size, intuitive display strong function, easy to operate. No special software in the field operator can directly modify the parameters to adapt to different work-site requirements. 
 There are five input: high, medium, low level and the two fault signals; 
 There are four outputs: control pump operation and output operation signals, 
 Relay contacts with a load capacity of 250V2A; 
 Program has an automatic descaling function; pumps work in rotation time is adjustable; failure automatically switches; level signal delay functions, an ordinary circuit do not function control box 
 Low voltage level detected by sampling, to avoid the strong signal of the level switch contacts oxidation, effectively extending the life float, effectively ensure the overall reliability of the equipment.
