6 Series ITV Working Principle When the input signal rises, the air supply soloenoid valve q turns ON. Due to this, part of the supply pressure passes through the air supply solenoid valve q and changes to output pressure. This output pressure feeds back to the control circuit r via the pressure sensor e. Here, pressure corrections continue until output pressure becomes proportional to the input signal, enabling output pressure that is proportional to the input signal.

Additionally, refer to page 8 as maximum set pressure differs on unit of standard measure. Note ) -wire type 4 to ma is not available. Power supply voltage (4 VDC or to VDC) is required. Note ) Select either analog output or switch output. Further, when switch output is selected, select either NPN output or PNP output. Note 4) Adjustment of numerical values such as the zero/span adjustment or preset input type is set based on the minimum units for output pressure display (e.g. to MPa). Note that the unit cannot be changed. Note ) The minimum unit for.9 MPa ( psi) types is psi. Note 6) 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 current. This is Ω or less for an input current of ma DC.

15 Electro-Pneumatic Regulator Series ITV// Working Principles When the input signal rises, the air supply solenoid valve q turns ON, and the exhaust solenoid valve w turns OFF. Therefore, supply pressure passes through the air supply solenoid valve q and is applied to the pilot chamber e. The pressure in the pilot chamber e increases and operates on the upper surface of the diaphragm r. As a result, the air supply valve t linked to the diaphragm r opens, and a portion of the supply pressure becomes output pressure. This output pressure feeds back to the control circuit i via the pressure sensor u. Here, a correct operation functions until the output pressure is proportional to the input signal, making it possible to always obtain output pressure proportional to the input signal.

32 Series ITV9 Working Principle When the input signal rises, the air supply soloenoid valve q turns ON. Due to this, part of the supply pressure passes through the air supply solenoid valve q and changes to output pressure. This output pressure feeds back to the control circuit r via the pressure sensor e. Here, pressure corrections continue until output pressure becomes proportional to the input signal, enabling output pressure that is proportional to the input signal.

39 Electronic Vacuum Regulator Series ITV9 Working Principle Working Principle Power supply Input signal q Vacuum pressure solenoid valve r Diaphragm Pressure display i Control circuit Output signal w Atmospheric pressure solenoid valve Atmospheric pressure u Pressure sensor e Pilot chamber When the input signal increases, the vacuum pressure solenoid valve q turns ON, and the atmospheric pressure solenoid valve w turns OFF. Because of this, VAC. and the pilot chamber e are connected, the pressure in the pilot chamber e becomes negative and acts on the top of the diaphragm r. As a result, the vacuum pressure valve t which is linked to the diaphragm r opens, VAC. and OUT. are connected, and the set pressure becomes negative. This negative pressure feeds back to the control circuit i via the pressure sensor u. Then, a correct operation works until a vacuum pressure proportional to the input signal is reached, and a vacuum pressure is obtained which is always proportional to the input signal.
