520MD-Website • Easy commissioning with fast, simple configuration • Self-calibration and auto-tune with adjustable gain selector • Industry standard HART communications • Low air consumption • Two-stage control design for faster response times and tighter control. • Standard Diagnostic functionality through ValveSight™ software

The Logix® 520MD Series digital positioner combines superior positioning and tuning functions with convenient setup and powerful diagnostic tools. The Logix 520MD positioner uses a multi-variable gain tuning algorithm which allows the positioner to make large step changes with minimal overshoot while achieving the resolution to respond to very small step changes. The Auto-tune procedure cycles the actuator to produce a measured response and selects gain values that provide
