EDP300 A1H1S2A A1R3 Intelligent locator

PositionMaster EDP300
It is a positioning instrument that can be configured electronically, with communication function Gauges are mounted on pneumatic linear or partially rotating actuators. Its design is small and compact, and can be used
Modular structure, with excellent cost performance.
The device is capable of fully automatic determination of various control parameters and can be based on the final control element
The timing is minimized and the control performance is better.
Pneumatic device An I/P with a follow-up pneumatic amplifier Module for controlling pneumatic actuators. Verified I/P modules will be proportionally
The permanent set point signal output by the CPU is converted into a pneumatic signal for tuning 3 channels 3 way valve.
The air flow for the pressurizer or reducer will be continuously regulated by the pressure, so that the jet can be obtained Out of the control effect. When the set point is reached, route 3 is 3
The central position of the valve is closed to minimize air consumption.
There are four different types of pneumatic devices available: for single-acting or double-acting actuators Each type has a “fail-safe” or “fail-hold” function.
The fail-safe function
When a power supply failure occurs, the locator outputs 1
The return spring of the pneumatic actuator moves the valve to the defined safe position.
If it is a double-acting actuator, the second output 2 is also pressurized. Fault Hold function
When a power supply failure occurs, the locator outputs 1 (and 2, if applicable) close, the pneumatic actuator stops the valve (” hold “) in the current position Buy. If the compressed air has a power supply failure, the locator will reduce the actuator. pressure Ch Controls
This locator has a built-in LCD indicator with a multi-line LCD Displays, as well as four buttons for testing, configuring, and monitoring real-time operations. Alternatively, the appropriate DTM/EDD can be used through the provided communication interface. communication
This locator supports communication between the HART5 and HART7.
Input/output
In addition to analog position set point input, the locator is also equipped with a digital input function , can be used to start the control system function of each dynamic equipment item. And use digital output work
If yes, it can output the alarm or fault information of the collection. Module design At any time, the basic model can be enhanced by retrofitting optional equipment. Optional modules can be installed for analog and digital feedback, emergency closing modules and for Pressure transducers for valve diagnosis. Universal analog input modules can also be installed in any 4… 20 mA Equipment for signal connection. Furthermore, mechanical position indicators, proximity on/off or 24 V are available Trimmer switch for indicating position independent of master function. diagnosis.
The positioner has three optional pressure transducers for reliable valve and pneumatic detection The drive device and the locator itself.
