- 2-wire type 4 to 20 mA DC is not available. Power supply voltage (DC 24V or DC 12~15V) is required.
- Select either analog output or switch output. Further, when switch output is selected, select either NPN output or PNP output. When measuring NITV analog output from 1 to 5 VDC, 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.
- 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. 10~5000 mbar). Note that the unit cannot be changed.
- 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 350Ω or less for an input current of 20mA DC.
- Proportional pressure regulator adopts electrical proportional method to achieve stepless control of outlet pressure. It can realize remote control and program control.
- Compared with hydraulic proportional valves, proportional pressure regulators are small in size, light in weight, compact in structure, light in weight and low in cost.
- The control of proportional pressure regulator is continuous control, and its characteristic is that the output quantity changes with the change of input quantity (current value or voltage value), and there is a certain proportional relationship between the output and input.
- Proportional pressure regulator has many types, which can be used with various electrical equipment and computers to control various electro-hydraulic systems. High control precision, flexible installation and strong anti-pollution ability.
