Siemens 6DR5110-0NN00-0AA0 Valve Positioner

Siemens SIPART PS2 6DR5110-0NN00-0AA0 is a smart electropneumatic positioner that translates a 4–20 mA control signal with HART communication into precise pneumatic actuation for both linear and quarter-turn valves. The unit uses a polycarbonate enclosure and provides robust process and pneumatic connections, including 1/2" NPT process threads and 1/4" NPT pneumatic outlets, making it suitable for integration into existing valve assemblies. A key feature is non-contacting position feedback (NCS), which offers wear-free sensing and long service life. This model is the standard version without explosion protection (Ex/nEx), configured for single-acting actuators, and includes depressurization of the actuator if electrical power is lost (fail-safe). Weighing about 0.9 kg, the 6DR5110-0NN00-0AA0 is designed to pair with Siemens SIPART PS2 drives and many actuators, delivering reliable control in demanding environments such as chemical processing, oil and gas, and water treatment where rugged valve control is essential.
