Flowserve Digital Positioner Logix 3400MD is a digital Foundation Fieldbus positioner with state-of-the-art piezo technology to provide superior performance and reliability. ITK 6.1 certified. Flowserve Digital Positioner Logix 3400MD is equipped with ValveSight Diagnostics function.
This advanced valve/actuator/positioner diagnostic equipment can issue an alarm when it detects abnormal conditions that can cause valve failure.
• Installation ease assured by automatic calibration and tuning
• Faster diagnostic feedback and summaries made possible by burst mode
• Easily configured using local buttons, FF handheld or ValveSight software
• Function blocks for AO, PID, DI, DO, input selector and output splitter
The Logix 3400MD digital positioner includes FOUNDATION fieldbus electronics for operating in a Fieldbus network as an H1device. It features standard fieldbus function blocks with manufacturer specific additions for enhanced operation. This Logix 3400MD digital positioner is a Link Master device, which means it can function as the backup Link Active Scheduler in a fieldbus network.
In addition to providing the Fieldbus Interface the Logix 3400MD digital positioner can also perform loop control functions. In conjunction with other FOUN DATION fieldbus compliant devices, its function block set allows the formation of an extensive set of basic control applications.
The Logix 3400MD digital positioner in conjunction with any valve will, in essence, form a Fieldbus valve. When configured in conjunction with an Honey well ST3000 fieldbus transmitter a complete control loop can be configured.
