ОПИСАНИЕ ПРОДУКТА
SIEMENS 7MB2001-0EA00-1DA0 - Electro-Pneumatic Valve Positioner
This device is an electro-pneumatic valve positioner from the SIEMENS SIPART PS2 series, engineered for precise control of linear and part-turn actuators in process automation. It converts an electrical 4-20 mA setpoint signal into a proportional pneumatic output pressure to accurately position a final control element, providing continuous position feedback via a 4-20 mA signal. This unit features intrinsic safety explosion protection and HART communication, making it suitable for robust field operation in hazardous industrial environments.
