    connecting the computer to measurement tools and sensors ulilized in students’ demonstration experiment and practical work

    > Technical features

    The measurement block admits simultaneous connection to 2 physical sensors. The #1 and #2 channels are intended to measure voltage and connect sensors of temperature, pressure, humidity, anglar speed, conductivity, pH, magnetic field, optoelectric time sensors and some others.
    Measurement range, (–5.. - 10) V
    Voltage measurement accuracy, up to 1%
    Input resistance, 10 kOhm
    Time measurement accuracy, 0.0002 s

    The #3 channel is intended to connect extender which may hold up to two sensors. External device (e.g. electromagnet) can also be controlled via the extender.

    External device features
    Input current, up to 0.45 A
    Supply voltage, up to 12 V
