LOGIX 520MD-02-W1DEE-00F0-DA6

The Logix® 520MD digital positioner combines superior positioning and tuning functions with convenient configuration and powerful diagnostic tools. The Logix 520MD positioner utilizes a multivariable gain-tuning algorithm that allows the positioner to perform large step changes with minimal overshoot, while still responding to very small step changes. The Autotune procedure cycles through the actuator to produce a measured response and selects gain values that provide optimal actuator performance. The Auto-Tune function includes a gain modifier selector that can be used to increase or decrease the calculated gain in order to achieve optimal performance. Simple DIP switch configuration for tuning mode and other common settings. For customized configurations, tuning sets can be modified with a handheld computer or ValveSight™ software, to adapt to a wide range of actuator sizes and types.
