Brief introduction
ACD-2K Digital pressure controller increases the alarm and control function on the basis of ACD-201. It has the local display and alarm relay contact output, can set the top and bottom alarm limitation and control return difference, and then output by relay. Signal isolation technique to forbid interference. It has the advantage of high control precision, quick response speed, stable performance, little volume and easy installation. It is the ideal replace product of electric contact gauge.
