Note 1: Select either analog or switch output.
Note 2: The above applies in control pressure 10 to 90 % with 24 VDC power voltage and working pressure set at the maximum control pressure 1.2 (=0.6 MPa).
Pressure may fluctuate if used for applications such as blowing only when the secondary side is a closed circuit.
Note 3: The above apply when working pressure and control pressure are maximum.
Note 4: The above apply when working pressure is maximum and the step is as follows: 50% F.S. -> 100% F.S.
50% F.S. -> 60% F.S.
50% F.S. -> 40% F.S.
Switch output: NPN or PNP open collector output, 50 mA or less, voltage drop of 2.4 V or less, PLC and relay compatible
