SCF8C-J-AS. Control para bombas Jacking según la norma australiana AS 2941
SCF8C-J-AS son instrumentos completos, de uso sencillo, automáticos y configurables, útiles para la gestión del funcionamiento de bombas Jacking hasta 7,5 kW entornos con circunstancias diversas.
Los controladores SCF8C-J-AS gobiernan el encendido y paro de la bomba Jacking y las protegen mediante la acción de diferentes alarmas, visualizan los valores e informaciones más relevantes y gestionan la comunicación tanto con los elementos de contorno como con los vigilantes remotos.
