Features & Benefits
- The Logix 500+ allows for fast commissioning, accurate and reliable control, and powerful diagnostic features that provide easy ways to determine when maintenance is required
- Logix 500+ limit switch kits are available to provide you with an independent verification of the position of the feedback shaft
- Auxiliary cards expand the possibilities of communication and control; up to 2 cards can be used at one time
- When using sweet natural gas, use threaded exhaust ports to exhaust gas to a safe environment
- Users can now obtain a new level of detailed real time diagnostic information with ValveSight DTM software
- The rugged, modular design provides protection from dirt and water ingress (IP 65/66), impact and vibration
- One-button setup automatically configures the zero, span and gain of the positioner for most valves in less than 60 seconds
- On-board pressure sensors that enable operators to identify and assess the severity of developing problems so action can be taken before a critical event
- Broad application versatility with industry-leading communication technologies, including analog or HART
- Optional module to remotely locate the positioner from the control valve
