Technical Specifications / Parameters Parameter Specification Model Fisher easy-Drive 200R (PROFIBUS PA) Type Digital, Electric, Motor-Driven Positioner for Rotary Valves Mounting Direct mounting on rotary actuators following VD/VDE 3845 (NAMUR) standard. Fieldbus Protocol PROFIBUS PA per IEC 61158-2 and IEC 61784-1, supporting Profile 3.02. Supply Pressure (Air Supply) 19 to 100 psig (1.3 to 7.0 bar) Output Pressure Equal to supply pressure (A Single-outlet design that pressures and exhausts one actuator chamber). Air Consumption Steady State: < 0.001 SCFM (< 0.02 NLPM) During Stroking: Varies with speed and actuator size. Air Flow Capacity (Cg) 0.45 Ambient Temperature Range -40°F to +185°F (-40°C to +85°C) Position Sensing Technology Non-contact, magneto-resistive. Enclosure Rating IP66/67 (NEMA 4X) Hazardous Area Approvals ATEX, IECEx, FM/CSA for Intrinsically Safe (IS) and Non-incendive (NI) applications. Materials Housing: Aluminum (Polyamide for IS versions); Sensing Shaft: Stainless Steel. Diagnostics Valve signature, step response, travel and pressure trends, performance alerts.
