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 appropriate 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. Easy DIP switch configuration for tuning mode and other common settings. For custom settings, tuning sets can be modified with a handheld or with ValveSight software, to accommodate a wide range of actuator sizes and types.

The Limitorque LRP provides durable functionality and prolonged service life through unique features such as piston support rods within the actuator, ensuring that side loads generated by the pistons are transmitted through bearings in the end cap and not the body. This eliminates the need for the body to be used as a loadbearing surface and promotes longer service life. The support rod design of the Limitorque LRP actuator distinguishes it from the standard rack and pinion design and offers reliable operation, performance stability and longer service life.
