Features
Description
Even with large changes in the unit power supply, the NV4a will act very stable both for offsetting the sensors zero point and for supplying an stable +/-4 VDC output that is linear with the sensors working range.
Application
The NV4a is used everywhere where a SEIKA sensor should be combined with a user-specific
demand for high voltage output / special wishes for filtering of
the sensor signal, plus where a non-stabilized 8...30VDC supply can be an advantage for the system.
For 0..5VDC output, please have a look at NV8a
For 4..20mA output, the NV6a is the correct solution.
