*1) The min. supply vacuum pressure should be 13.3 kPa less than the max. vacuum pressure setting value.
*2) DC4 to 20 mA is not possible with the 2-wire type. Power supply voltage (DC24 V or DC12 to 15 V) is required.
*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 350 Ω or less for an input current of DC20 mA When measuring ITV analog output from DC1 to 5 V, if the load impedance is less than 100 kΩ, the analog output monitor accuracy of within ±6% (full span) may not be available. The product with the accuracy of within ±6% is supplied upon your request. Output pressure remains unaffected.
*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.
*5) Please contact VPC regarding indication with other units of pressure.
*6) Refer to the table below for communication specifications.
