NV6a Filtering signal conditioner for sensor signal matching to a 4…20mA, 2-wire interface Features • • • • • • low noise and low drift 2-wire connection – power supplied by current loop loop current limitation integrated reverse polarity protection highly stable sensor supply voltage protection against reverse polarity of sensor connection • • • • • zero position and gain adjustable via potentiometers electronic components hermetically sealed optionally frequency programmable, active rd 3 order low pass filter optional high pass filter different connector options Description The NV6a amplifies, filters and normalizes the output signals of SEIKA sensors. The symmetrical output signal enables unproblematic subsequent signal processing on the basis of 4…20mA current loop technology. The NV6a does not require a separate supply voltage, as the internal operating voltage feeds off the current loop. The NV6a furthermore provides a highly stable 5V sensor supply voltage with short circuit current limitation. Multiple internal switching variants allow for optimal adaptation of signal processing parameters, such as settling time, filter cut-off frequencies and amplification and zero point adjustment, to the measuring task. Application The NV6a has its application anywhere a SEIKA sensor is, without much expenditure and under optimal compatibility, to be connected to measuring equipment operating on 4…20mA, 2-wire current loop basis and subsequent adjustment of amplification and zero position are necessary. Typical applications are the coupling with memory programmable control systems and the signal transmission over long distances with little transmission line setup.

Attention! Sensor GND and NV6a GND (both at same potential) must be isolated from current loop! In a multiaxial arrangement (e.g. SW3), all sensor grounds must be isolated from each other. When ordering, look for “Sensor internally insulated, compatible with NV6a”! This restriction is not applicable to signal conditioners with voltage output (NV4a, NV8a, NG..U, etc.)! Since the supply voltages for the NV6a and the sensor feed off the current loop (they require at least 3mA), a terminal voltage of 8V to the NV6a must be guaranteed in order to ensure proper functionality even for the maximum loop current of approx. 24mA (highest voltage drop across load resistance).
