Principle of operation: The transducer signal measured at the converter input is converted into a standardised output signal that is proportional to the input and lends itself to further customised processing, for instance, in a machine controller. General notes on Type VF5.. Description VF5.. • Signal input for a NORIS standard frequency signal Input signal The NORIS standard signal corresponds to a rectangular voltage with • Suitable to evaluate sensors of the FT.. and FA.. series an amplitude that corresponds to • Input range: 0 ... 10.000 Hz (according to type) the operating voltage applied. This • Maximum range frequency between: 50 ... 100 Hz (VF500..), results in a signal that is immune to interference and tolerates consider- (Factory-set frequency adjustment) able changes in the operating volt- To avoid triggering errors the frequency full range set in factory must be the highest frequency of the measuring chaine. age. The operating voltage required by the sensor is provided by the measuring transducer. Electric isolation The operating voltage and sensor input are electrically isolated from the output signal. Therefore, multiple operation of amplifiers and evaluation devices is possible at the same operating voltage and from only one sensor. Operating status display by LED The green LED will be lit when the operating voltage is applied and the device is working normally. Output signal The output signal generated is a standardized voltage of 0 ... 10 V/DC or 2 ... 10 V/DC or, respectively, a standardized current of 0 ... 20 mA or 4 ... 20 mA. The output signal follows the input signal strictly linearly (deviation < 0.1%). The output signal can be used to supply additional devices, such as indicating instruments and limit-value switches. Attention should be paid to the maximum driver ca
