Siemens 6DR5510-0NG00-0AA0 PS2 Positioner

Siemens SIPART PS2 6DR5510-0NG00-0AA0 is a smart electropneumatic positioner that provides precise position control for pneumatic actuators in process applications. The PS2 PA SA variant supports PROFIBUS-PA communication and is designed for single-acting operation on pneumatic linear and part-turn actuators. Housed in a Makrolon polycarbonate enclosure, the unit features electrical connection via M20x1.5 and pneumatic port G 1/4, with no limit monitor and no option module included. This version is without explosion protection (non-Ex), and in normal operation offers a fail-safe depressurization of the actuator in the event of loss of electrical power. The 6DR5510-0NG00-0AA0 order code corresponds to this configuration, and the device is typically deployed to couple valve positioning with fieldbus control networks in process plants. Typical applications include valve actuation and process control in chemical, oil and gas, and refining operations, where robust, bus-enabled positioning supports accurate flow control, repeatable travel, and reliable integration with PLC and process-control systems.
