(Maximum stations) Example) IITV--7 Note) A DIN rail with the length specified by the number of stations is attached to the manifold. For dimensions of the DIN rail, refer to the external dimensions. How to Order Manifold Assembly (Example) Indicate the part numbers of electro-pneumatic regulators and options to be mounted below the manifold part number. Example) Due to the common supply/exhaust feature, note that different pressure range combinations are not available. IITV- set (Manifold part no.) ITV-MS sets (Vacuum regulator part no. (, stations)) ITV-ML set (Vacuum regulator part no. ( stations)) Indicate part numbers in order starting from the first station on the D side. Note) Combination with having different pressure ranges is not available due to common supply/exhaust features. The asterisk ( ) specifies mounting. Add an asterisk ( ) at the beginning of electro-pneumatic regulator part numbers to be mounted.

3 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.
