    AC Current Measurement Interface UD-ACI330

    The UD-ACI330 AC Current Measurement Interface was developed especially for measuring the AC current in circuits with motors, heating and others. Employing components from the best electronic manufucturers in the world and digital measurement technology, the ACI330 is a precise and robust module for the industrial environment.

    The models UD-ACI330/01 and UD-ACI330/05 must be used in conjunction with a Current Transformer (C.T.) with secondary nominal currents of 1A and 5A, respectively. With this topology, any primary current flowing in the primary circuit can be measured with precision and safety.

    On the other hand, the model UD-ACI330/20 can be connected directly to the current line with a maximum capacity of 13. Arms. In this case, no C.T. is needed.

    The analog output signal provided by the UD-ACI330 is in the format of 0 – 10 V or 4 – 20 mA, being suitable for use with PLC’s.

    Please, read in the datasheet more application information about this product.

    Voltage-to-Frequency and Current-to-Frequency Converter

    The C450 is a voltage-to-frequency and current-to-frequency converter that generates a precise train of pulses whose frequency is linearly proportional to an input control analog signal.

    The C450 may be employed to perform the following functions: a) Step-motor speed control by means of an analog signal; b) Transmission of analog signals over great distances by converting them previously to a train of pulses; c) Analog signals reading in fast digital inputs of PLC’s and CNC’s.

    Potentiometric Transducer Interface

    Potentiometric Transducer Interface

    The Potentiometric Transducer Interface model UD-A440 was especially designed for isolate a potentiometric transducer from the analog input of PLC’s/CNC’s, avoiding the non-linear error caused by a direct connection. Besides linearizing the transducer response, the A440 supplies a very stable and precise reference voltage of 10.000 Vdc to make your measurements absolutely reliable.

    SHORT-CIRCUIT PROTECTION: The 10.000 V reference voltage is fully protected against short-circuits, a situation that may occur if the is the cursor terminal is inverted with the ground terminal at the transducer.

    HIGH SPEED RESPONSE: The UD-A440 responds with high speed to any position change of the transducer (up to 4000 m/s). Even the position of the transducer changes very rapidly, the output signal of the A440 will be precisely in phase with the analog voltage at the input.
