Note 2) 4 to 2 ma DC is not possible with the 2-wire type. Power supply voltage (24 VDC or to 5 VDC) is required. Note 3) Value for the state with no over current circuit included. If an allowance is provided for an over current circuit, the input impedance varies depending on the input power supply. This is 35 Ω or less for an input current of 2 ma DC. Note 4) Either analog output or switch output must be selected. Furthermore, when switch output is selected, either NPN output or PNP output must also be selected. Use caution that the preset input type is not equipped with an output signal function. Note 5) Please contact SMC regarding indication with other units of.

3 Electronic Vacuum Regulator Series ITV29 Working Principle Working Principle Power supply Input signal q Vacuum r Diaphragm Pressure display i Control circuit Output signal w Atmospheric Atmospheric u Pressure sensor e Pilot chamber When the input signal increases, the vacuum solenoid valve q turns ON, and the atmospheric w turns OFF. Because of this, VAC. and the pilot chamber e are connected, the in the pilot chamber e becomes negative and acts on the top of the diaphragm r. As a result, the vacuum valve t which is linked to the diaphragm r opens, VAC. and OUT. are connected, and the set becomes negative. This negative feeds back to the control circuit i via the sensor u. Then, a correct operation works until a vacuum proional to the input signal is reached, and a vacuum is obtained which is always proional to the input signal. Block Diagram VAC.
