Programmable Logic Control

 

Nowadays , PLC is widely employed in the marine electronic equipments , as simple as TV lifter and BW pump control , as complicated as PTO hydraulic control and electric broad control , with our highly familiar logic knowledge , projects can be started from sketch , design implementation , flow simulation and finally in field hot test.

Sailing boat PTO hydraulic pump needs a very special PLC to monitor , sense and control the basic operations of the thruster up/down , port/starb trim , engage/disengage , oil alarm , pump pressure step etc.

Even black water pump PLC needs to monitor tank level , pump running current , level alarm , auto /manual mode selection.
