Product introduction
ABB EDP300 Digital Positioner PositionMaster EDP300
Overview
Overview
The PositionMaster EDP300 is an electronically configurable positioner with communication capabilities designed for mounting to pneumatic linear or part-turn actuators. It features a small and compact design, a modular construction, ABB EDP300 Digital Positioner and an excellent cost-performance ratio.Fully automatic determination of the control parameters and adaptation to the final control element yield considerable time savings and an optimal control behavior.
Pneumatics
An I/P module with subsequent pneumatic amplifier is used to control the pneumatic actuator. The well-proven I/P module proportionally converts the permanent electrical setpoint signal from the CPU into a pneumatic signal used to adjust a 3/3- way valve.ABB EDP300 Digital Positioner The air flow for pressurizing or depressurizing the actuator is continuously adjusted. As a result, excellent control is achieved. When reaching the setpoint, the 3/3-way valve is closed in center position to minimize the air consumption.ABB EDP300 Digital Positioner Four different pneumatics versions are available: for singleacting or double-acting actuators, each with “fail-safe” or “failfreeze”
function.
“Fail-safe” function
If the electrical supply power fails, the positioner output 1 is depressurized, and the pneumatic actuator’s return spring moves the valve to the defined safe position.ABB EDP300 Digital Positioner In case of a double-acting actuator the second output 2 is additionally pressurized.
“Fail-freeze” function
If the electrical supply power fails, the positioner output 1 (and 2, if applicable) is closed and the pneumatic actuator stops(“freezes”) the valve in the current position.ABB EDP300 Digital Positioner If the compressed air supply power fails, the positioner depressurizes the actuator.
Use
The positioner has a built-in LCD indicator with a multi-line LCD display and 4 operating buttons for commissioning,configuration, and monitoring during live operation.ABB EDP300 Digital Positioner Alternatively, the appropriate DTM/EDD can be used via the available communication interface.
Communication
The positioner supports HART5 and HART7 communication.
Inputs / Outputs
In addition to its input for the analog position setpoint, the positioner is equipped with a digital input which can be used to activate control system functions in the device. A digital output allows you to output collective alarms or fault messages.
Modular design
The basic model can be enhanced at any time by retrofitting optional equipment. Option modules for analog and digital feedback, an emergency shutdown module, and pressure sensors for valve diagnostics can be installed.
A module for a universal analog input can also be installed to which any device supplying a 4 … 20 mA signal can be connected.
Additionally, a mechanical position indicator, proximity switches or 24 V microswitches are available for indicating the position independently of the mother board function.
Diagnostics
The positioner has three optional pressure sensors which can be used for reliable diagnostics of the valve, the pneumatic drive, and the positioner.
