Key Parameters & Specifications 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, 0-100 mV, etc. Input Impedance ~850 ohms at 20 mA (for 4-20 mA, 2-wire). Varies for other signals. Power Supply For 2-wire 4-20 mA, the loop power supply is typically 12-45 VDC, depending on load. Pneumatic Output Output Pressure Ranges Multiple standard ranges, e.g.: • 3-15 psig (0.2-1.0 bar) • 3-27 psig (0.2-1.9 bar) • 6-30 psig (0.4-2.1 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 (including linearity, hysteresis, and dead band). Sensitivity Typically 0.05% of span. Air Consumption (Static) Very low (e.g., < 0.2 SCFH) when output is stable. Air Flow Capacity (Dynamic) Very high. Up to ~30 SCFM (approx. 50 m³/h) to quickly fill and exhaust actuator volumes. Environmental & Physical Enclosure Rating NEMA 4X (IP66) - Weatherproof, watertight, and corrosion-resistant. Ambient Temperature Range Standard: -40°F to 180°F (-40°C to 82°C). Extended: -50°F to 225°F (-46°C to 107°C) with specific options. Material Aluminum enclosure with corrosion-resistant epoxy coating. Stainless steel hardware. Mounting Directly to actuator (with bracket) or via 1/2" NPT conduit connection. Approvals Intrinsic Safety & FM/ATEX Available with appropriate intrinsic safety barriers or as an entity-approved device (FM, CSA, ATEX).
