Schneider MD40A - 24 Valve Actuator Product Description​ Part Number: 875 - 1039 - 000​ The Schneider MD40A - 24 Valve Actuator is a high - performance device designed for reliable operation in various applications.​ Power Supply​ It offers flexibility in power input with options for 24 V AC (+20%) at 50 - 60 Hz or 24 V DC (+20%). This wide range of power compatibility ensures it can be easily integrated into different electrical systems.​ Power Consumption​ In Operation: Consumes only 4 W at nominal torque, making it energy - efficient during active use.​ At Rest: Reduces power draw to 2 W, further optimizing energy usage. For wire sizing, it has a rating of 6.5 VA.​ Connection Cable​ Comes with a 1 - m (3.3 - ft) long connection cable featuring 4×0.75 mm (AWG 18) wires. This cable is suitable for stable signal and power transmission.​ Control Signals​ Control Signal X: Operates with a 0 - 10 V DC signal. The input resistance is 100 k Ohm, and the operating range is 2 - 10 V DC (with a ±5% tolerance for setting the angle of rotation).​ Position Feedback Y: Provides a 2 - 10 V DC feedback signal (max. 1 mA), enabling accurate monitoring of the actuator's position.​ Mechanical Specifications​ Direction of Rotation: Reversible, controlled by a 0/1 switch at the switch position.​ Angle of Rotation: Can achieve a maximum of 95 degrees, which is adjustable by mechanical stops for precise operation.​ Torque: Delivers a minimum torque of 40 Nm (360 in - lb) at nominal voltage, ensuring reliable valve operation.​ Running Time: Completes its operation in 150 s.​ Position Indication: Features a mechanical position indication for easy visual monitoring.​ Manual Override: Equipped with a gearing latch that can be disengaged with a pushbutton, which is self - resetting. It also has a manual locking feature for added safety and convenience.​ Environmental Specifications​ Ambient Temperature:​ Operation: Can function in temperatures ranging from - 30 to +50 °C (-22 to +122 °F), making it suitable for a wide variety of environments.​ Storage: Can be stored in temperatures from - 40 to +80 °C (-40 to +176 °F).​ Sound Power Level: Produces a maximum sound power level of 45 dB (A), ensuring quiet operation.​ Maintenance and Weight​ Maintenance: Is maintenance - free, saving you time and cost in the long run.​ Weight: Weighs approximately 1.7 kg (3.8 lb), making it relatively lightweight and easy to install and handle.​
