Key Parameters Category Parameter Name Description & Typical Values Electrical Input Input Signal Standard: 4-20 mA DC (2-wire). Other Options: 10-50 mA, 1-5 VDC, etc. Input Impedance ~850 ohms at 20 mA (for 4-20 mA, 2-wire). Power Supply For 2-wire 4-20 mA, the loop power supply is typically 12-45 VDC. Pneumatic Output Output Pressure Ranges Multiple standard ranges, e.g.: • 3-15 psig (0.2-1.0 bar) • 6-30 psig (0.4-2.1 bar) • Other ranges up to 120 psig (8.3 bar) Air Supply Pressure Must be at least 3-5 psi (0.2-0.35 bar) above the maximum required output pressure. Typical max supply: 20 to 150 psig (1.4 to 10.3 bar). Performance Accuracy Typically ±0.5% of span. Sensitivity Typically 0.1% of span. Air Consumption (Static) Very low (e.g., < 0.5 SCFH) when output is stable. Air Flow Capacity (Dynamic) Very High. Up to ~30 SCFM (approx. 50 m³/h). Environmental & Physical Enclosure Rating NEMA 4X (IP66) - Weatherproof, watertight, and corrosion-resistant. Ambient Temperature Range -40°F to 180°F (-40°C to 82°C). Material Aluminum enclosure with corrosion-resistant coating. Mounting N480: Side-mounted on actuator yoke. N481: Bottom-mounted to actuator. Approvals Intrinsic Safety Available with appropriate intrinsic safety barriers (FM, CSA, SAA).
