TopWorx PD Series Smart Valve Positioner PD100 / PD200
Description
A compact smart positioner for linear and rotary valves
The TopWorx PD Series smart valve positioner is offered as the PD100 and the PD200. It fits linear and rotary actuators, single or double acting, with direct or reverse action, and uses Hall-effect contactless position sensing. A local liquid crystal display, autocalibration and three buttons make set-up easy, and the PD200 adds HART capability with configurable alarms and magnetic buttons that can be operated with a magnetic key without removing the cover.

Ordering code
The datasheet codification builds a code such as PD200-HSNGK30000-ES from model, input and communication (C 4-20 mA for PD100, H HART 7 for PD200), feedback output (F isolated 4-20 mA feedback for PD100; S feedback plus two mechanical alarm switches for PD200), connection N (single conduit entry with 1/4 in NPT manifold), manifold G (two pressure gauges in psi), actuator type (RN rotary NAMUR adapter, K3 linear lever 12-120 mm, K4 linear lever 80-200 mm), mounting bracket (00 means none, sold separately), options and hazardous area class (GP, EN or ES). Not all combinations are compatible, so confirm with TopWorx.
Selection notes
Choose the PD100 for analog control and general purpose or non-incendive areas, and the PD200 where HART, alarms or intrinsic safety are needed. The hazardous-area marks are shown as pending on this edition of the datasheet, so verify certification status before use in a classified area. The sheet gives no actuator-size limit beyond the stroke range.

About brand
TopWorx is the valve controls and limit switch brand of Emerson, based in Louisville, Kentucky, USA. Its products mount on valve actuators to show whether a valve is open or closed, send switch or analog signals back to the control system and, in some models, operate the actuator pilot valve. Seven Star LLC, an independent supplier in Muscat, lists products from the manufacturer's manuals and datasheets and quotes against the exact model code.
TopWorx product groups
The documents on this site cover GO Switch leverless limit switches, the D-Series, TX-Series, TV-Series and K-Series discrete valve controllers, the DVR valve position monitor and the PD Series smart valve positioner. Options in these documents include GO Switch, mechanical and inductive sensors, 4-20 mA and HART transmitters, FOUNDATION Fieldbus, AS-i, DeviceNet and PROFIBUS communication, integrated pilots and explosion-protected enclosures.
Ordering TopWorx products: what we need
Send the full model code from the nameplate or the datasheet nomenclature, the actuator make, mounting pattern and size, the supply voltage and signal type, the hazardous-area certification and the quantity. Many options cannot be combined, so we confirm the code against the manufacturer's documentation before quoting.
