TISSIN TS900RC35S3A Electro-pneumatic Valve Positioner

The TISSIN TS900RC35S3A Electro-Pneumatic Valve Positioner is a smart electro-pneumatic device that translates a 4–20 mA DC control signal into precise movement of a rotary pneumatic actuator to position globe, butterfly, ball, and other pneumatically actuated valves. It is used in industrial process control to achieve accurate valve modulation in chemical processing, oil and gas, power generation, water treatment, and manufacturing facilities, and supports new installations, retrofit projects, and replacement of existing positioners. Key specifications include a 4–20 mA input signal with 500 Ω input impedance, supply pressure from 0.14 to 0.7 MPa (20–100 PSI), air connection 1/4 in. NPT (or PT 1/4 depending on configuration), conduit connection 1/2 in. NPT (or M20 depending on configuration), enclosure rating IP66 / NEMA 4X, aluminum die-cast housing, ambient operating temperature −30°C to +80°C, linearity ±0.5% F.S., and repeatability ±0.3% F.S.; it is compatible with rotary pneumatic actuators and used for pneumatic control valve positioning and process control in refineries, petrochemical plants, power stations, water and wastewater facilities, pharmaceutical production, and food and beverage processing. Common replacements include Siemens SIPART PS2 6DR5 Series, ABB EDP300 Series, and Fisher FIELDVUE DVC6200.
