Smart Electro Pneumatic Positioner YT3300 Valve Positioner

The Electro-Pneumatic Positioner YT-3300

The Electro-Pneumatic Positioner YT-3300, a remarkable lineup within the realm of industrial automation, is a group of highly advanced intelligent valve positioners. Engineered with state - of - the - art technology and precision - focused design principles, these valve positioners play a pivotal role in a wide range of industrial processes.

Design features

• Auto calibration. Simple menu structure with options to auto-calibrate all parameters or zero and end points only.

• LCD display. Alphanumeric digital display for process values and calibration.

• Partial Stroke Test (PST). Fully-adjustable Partial Stroke Test. All functionality can be performed and selected locally, through push buttons, or remotely with communication protocol.

• Analogue Output. Analogue and digital feedback signals with 4-20 mA, mechanical and proximity switch options.

• PlD control. Pre-calibrated and user-configurable variables via front panel pushbutton menu.

• Auto/manual switch. Enables closed-loop automatic valve position control or manual positioning via the A/M switch. The manual mode is useful for troubleshooting, calibration, system testing or as a manual bypass.

• HART communication. Allows commands, position feedback and diagnostics to be sent digitally over the current loop.

• Profibus Process Automation (PA). Manages equipment via a process control system in process automation applications. The PA variant is designed for use in hazardous areas (Ex zones 0 and 1). The Physical Layer, with over the bus power, limits current flows so that explosive conditions are not created, even if a malfunction occurs.The number of devices attached to a PA segment is limited by this feature. However, PA uses the same protocol as DP, and can be linked to a DP network using a coupler device. The much faster DP acts as a backbone network for transmitting process signals to the controller. This means that DP and PA can work tightly together, especially in hybrid applications where process and factory automation networks operate side by side.

• Foundation Fieldbus. A bi-directional communications protocol used for communications among field devices and the control system. lt utilises twisted pair or fibre media to communicate between multiple nodes (devices) and the controller. The controller requires only one communication point to communicate with up to 32 nodes, this is a significant improvement over the standard 4-20 mA communication method which requires a separate connection point for each communication device on the controller system.

• Front panel pushbuttons for configuration. Four robust and positive acting pushbuttons for field configuration.

• Non-contact sensor for increased performance for high frequency operating valves and an enhanced lifetime.
