  • Introduction
  • Specifications
DG□ series control point adjustment is a control point unit of DDZ-Ⅲ type of electric unit combination instrument. It includes constant current given, ratio given and alarm given.
DGA-2000S constant current adjustment can offer DC 4～20mA constant current. It can be use as an external offset of ratio control point adjustment and other operating unit. In addition, if required the executing agency action precise, it can be used as an operator to connect with electrical converter or electric valve positioner directly.
DGB series ratio control point adjustment is mainly applied used in two or more flow parameters required to maintain a certain percentage of the control system to operate ratio of input signal and output 4～20mA signal.
DGJ series alarm is mainly used to measure and alarm if the signal is out of limit. It also can indirectly drive the implementing agencies to carry out location-type regulation, or interlocking control.
