    Rotation Monitor DSM5000A

    The Rotation Monitor DSM5000A was designed to receive the signals generated by proximity or magnetic sensors installed on a spinning axis to measure its rotation. With two redundant sensor inputs, the DSM5000A outputs voltage (0 – 10V) and current (4 – 20 mA) proportional signals plus two digital signals to monitor the status of the rotation sensors and a relay alarm output.

    For use in every situation where monitoring the rotation is a critical task, the DSM5000A can be field programmed to the full scale rotation range as desired. A rotation level can also be programmed to activate the alarm relay by means of the front keyboard.

    The 4-digit display allows the reading of the input signals as frequency or as RPM. The module is powered by 24 Vdc. DIN rail mounting. 


    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 resistances and others. Employing components of 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 13.5 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.





    Frequency-to-Voltage Converter CFV300AuP Precision

    The Precision Frequency-to-Voltage/Current Converter uses digital technology and is capable of converting ultra-low/low frequency signals, eliminating the ripple generated in conventional circuits. 0-10V or 4 – 20 mA output. The full scale range can be factory set from 5 to 50000 Hz. Excellent linearity and precision. Mounts on DIN rail.


    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 to 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 cursor terminal is inverted with the ground terminal at the transducer during installation.

    HIGH SPEED RESPONSE: The UD-A440 responds with high speed to any position change of the transducer (up to 2000 mm/s). Even if 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.
