Technical Parameters Category Parameter Specification / Description General Model 67CF-1663-38501 Type Digital Pressure Reducing Regulator Product Line FIELDVUE Primary Protocol HART Input & Control Input Signal 4 to 20 mA DC, two-wire Supply Pressure (Max) 400 psig (27.6 bar) Setpoint Range (P2) Defined by the "1663" configuration. This code typically corresponds to a specific range, likely covering a common span like 3-60 psig or 3-115 psig. Performance Output Pressure Range 0 to 100 psig (0 to 6.9 bar) Accuracy ±0.5% of span (typical) Supply Pressure Effect ±0.2 psig for a 50 psig supply change Flow Capacity (Cv) Defined by the "1663" configuration. Environmental Ambient Temperature -40°F to 175°F (-40°C to 80°C) Enclosure Rating Type 4X, 6 (IP66/67) Hazardous Area Certifications FM/CSA & ATEX/IECEx: Explosion-proof & Intrinsically Safe
