The ND7000 is a 4 to 20 mA powered microcontroller- based digital valve controller.
The device contains a Local User Interface (LUI) enabling local configuration.
The powerful 32-bit microcontroller controls the valve position.
Self-diagnostics guarantees that all measurements operate correctly.
ND7000 diagnostics includes four Offline Tests.
The test results can be compared with earlier tests.
