ABB EDP 300 Valve positioner

The PositionMaster EDP300 is an electronically configurable positioner with communication capabilities, designed for mounting on pneumatic linear or part-turn actuators. It features a compact design, modular construction, and an excellent cost-performance ratio. Fully automatic determination of the control parameters and adaptation to the actuator allow for considerable time savings as well as optimum control behaviour. The extended diagnostics feature of the PositionMaster EDP300 provides the user the opportunity to perform selectable valve performance diagnostics and to schedule Control Valve preventive maintenance as determined by the results to ensure increased system availability and to minimize unforeseen cost intensive failures. In this document we provide examples of typical online and offline tests that can be performed by the EDP300 positioner:

• Stainless steel housing
• Non-contact position sensor
• High air capacity
• Operation with natural gas
• Extended diagnostics
• Graphical display
• Universal analog input
• Analog HART communication
• Easy plug in modules
• Worldwide Intrinsic Safety approvals
• Remote sensor version
  – Advanced vibration resistance 2 g, 300 Hz
  – Protection class IP 67
