Values may vary depending on actuator configuration and operating environment.
The positioner receives a 4–20 mA command signal from the control system. Internal digital controls compare the signal with feedback from the valve stem or shaft, adjusting pneumatic output to move the valve to the required position. The Logix 3800E model additionally captures diagnostic information including cycle count, travel deviation, air usage patterns, and position errors to support predictive maintenance strategies and reliability programs.
Can the Logix 3800 and 3800E be used on rotary valves?
Yes, both models work with rotary actuators using mounting kits.
Is HART communication available on both models?
Yes, HART support is standard for remote access and diagnostics.
What is the difference between Logix 3800 and 3800E?
The 3800E offers extended diagnostics and enhanced monitoring, providing more data for maintenance planning.
Are these models suitable for control valve retrofits?
Yes, they are widely used for upgrading pneumatic or older digital positioners.
Do these positioners support predictive maintenance?
The Logix 3800E includes diagnostics that support predictive strategies when integrated with monitoring systems.
