Claims (1)
の入力ラインと、その弁により制御される物理量
の測定値と設定目標値の偏差を検出するＰＩＤ調
節計の出力ラインの間に、調節自在の設定電圧と
上記出力ラインを経た信号のいずれかを選択的に
導入する切換回路を設けるとともに、弁の開閉を
指示する操作指令が発せられた初期のみ上記設定
電圧を導入させその初期経過後は上記出力ライン
を経た信号を導入させる切換制御部を設けたこと
を特徴とする電動操作器。 A freely adjustable set voltage is installed between the input line of the motor drive unit that controls the valve opening and the output line of the PID controller that detects the deviation between the measured value of the physical quantity controlled by the valve and the set target value. In addition to providing a switching circuit that selectively introduces either the signal passed through the above output line or the signal passed through the above output line, the above set voltage is introduced only at the initial stage when an operation command to open/close the valve is issued, and after that initial period, the above output line is switched on. An electric operating device characterized in that it is provided with a switching control section that introduces a signal that has passed through.
