Technical Parameters Category Parameter Specification / Description General Model 67CFR-226 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 "-226" code. This typically indicates a specific range, commonly 3 to 60 psig (0.2 to 4.1 bar). Performance Output Pressure Range 0 to 60 psig (0 to 4.1 bar) - *This is the key specification defined by the -226 code.* Accuracy ±0.5% of span (typical) Supply Pressure Effect ±0.2 psig for a 50 psig supply change Flow Capacity (Cv) Specific to the "-226" configuration. Likely a standard capacity for general instrument air applications. 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
