*1: Refer to the figure for the relationship between the set pressure and input signal.
*2: 2-wire type 4 to 20 mA is not available. Power supply voltage 24 V DC is required.
*3: Select one of either analog output or switch output. If switch output is selected, select either NPN output or PNP output. When measuring analog output from 1 to 5 V DC with a load impedance of less than 100 kΩ, an analog output accuracy of within ±6% (full span) may not be available.
*4: Adjustment of numerical values such as the zero/span adjustment is set based on the minimum unit for the output pressure display. The unit cannot be changed.
*5: The above characteristics are confined to the static state. When air is consumed on the output side the pressure may fluctuate.
*6: This product does not conform to the High Pressure Gas Safety Law (Japan).
Working principle diagram
When the input signal rises, air supply solenoid valve (1) turns ON, and exhaust solenoid valve (2) turns OFF. Therefore, supply pressure regulated by built-in regulator (3) passes through air supply solenoid valve (1) and is applied to pilot chamber (4). The pressure in pilot chamber (4) increases and operates on the upper surface of diaphragm (5).
As a result, air supply valve (6) linked to diaphragm (5) opens, and a portion of the supply pressure becomes output pressure.
This output pressure feeds back to control circuit (8) via pressure sensor (7). Here, a correction 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.
