 I. Function description of dvc6200: Applicable actuator: Feedback rod angle: from 40° to 20°; when the angle is greater than 20°, it is achieved through an angle amplification mechanism. ) Bypass operation: automatic/manual switch (applicable only to single-acting actuators). Supply pressure: 140 to 700 kPa (1.4 to 7.0 kgf/cm2). Single-acting and double-acting actuators. Straight-stroke actuators. Control signal input: 4-20 mA DC signal. Input impedance: up to 3000/20 mADC for AVP80 type. Output characteristic: linear. Air consumption: 4 N/minute (maximum value at 140 kPa/1.4 kgf/cm2), 5 N/minute (maximum value at 280 kPa/2.8 kgf/cm2), 6 N/minute (maximum value at 500 kPa/5.0 kgf/cm2), 10 N/minute (maximum value at 400 kPa/4.0 kgf/cm2); for double-acting actuators. Maximum supply air flow rate: 110 L/N/minute at 140 kPa/1.4 kgf/cm2 ; At 400 kPa (4.0 kgf/cm2), the output pressure is 250 L/N per minute (for double-acting actuators); the balanced pressure is 55+5% (only for double-acting actuators). Lightning protection: peak surge voltage: 12 kV ; Peak surge current: 1000A. Allowable vibration level: 2G (5 to 400 Hz) when standard mounting components are used on the DVC6200 actuator. Ambient temperature: -40°C to +80°C. Limitations on ambient humidity: relative humidity of 10% to 90%. II. The DVC6200 is easy to use and maintain: ① It has an automatic setup function; its setup software is a fully automated configuration program. Unlike other brands’ dvc6200, the SVP3000 Alphaplus does not require external devices. To carry out the basic configuration, no computer or special communicator is required; simply press the switch to run the program. ②The optimal setting for various application scenarios: forced full closure. When the input signal is below 0.5%, the dvc6200 routes power to the actuator mechanism via a bypass, ensuring reliable full closure of the valve. It is suitable for both single-acting and double-acting actuators: with the help of a double-acting amplifier, the SVP can be installed on double-acting actuators. Suitable for linear actuators. \"Note: For functions such as communication, diagnosis, and position division, the DVC6200 locator can be used.\"

Are all current DVC6200 models equipped with a linkless feedback mechanism to avoid the effects of wear and vibration?
