The PositionMaster EDP300 is a digital positioner for pneumatic linear or rotary actuators, with HART5® and HART7® communication, a compact aluminum or stainless steel 1.4404 (316L) housing, and IP65/NEMA 4X rating. It supports single or double-acting actuators with fail-safe or fail-freeze functions, operates on supply pressures of 1.4 to 10 bar, and delivers 40 kg/h air capacity. It meets ATEX, IECEx, cFMus, NEPSI, KOSHA, and PESO certifications for explosive atmospheres, qualifies for SIL2, and complies with DNV for maritime use. Mounting follows DIN/IEC 534 for linear and VDI/VDE 3845 for rotary actuators. Operating temperature range is −40 to 85 °C with an integrated LCD and four pushbuttons for commissioning and diagnostics.
The PositionMaster features a small and compact design, a modular construction, and an excellent cost-performance ratio. Fully automatic determination of the control parameters and adaptation to the positioner allow for considerable time savings as well as optimum control behavior. Because of its properties, the positioner is suited for even the most challenging operating conditions.
