NELES® ND7000 DIGITAL VALVE CONTROLLER - 2

TECHNICAL DESCRIPTION The ND7000 is a 4-20 mA powered microcontroller- based digital valve controller. The device contains a Local User Interface (LUI) enabling local configuration. A PC with FieldCare software can be connected to the ND7000 itself or to the control loop. The powerful 32-bit microcontroller controls the valve position. □ Valve position with contactless sensor □ Actuator pressures, 2 independent measurements □ Spool valve position Self-diagnostics guarantees that all measurements operate cor- rectly. After connections of electric signal and pneumatic supply the micro...
