Sensor-CASSY

LD DIDACTIC GmbH
Summary as PDF

Description

Cascadable interface for measured-value recording.

  • for connection to the RS-232 serial interface of a computer, another CASSY module or the CASSY display
  • Sensor-CASSY and Sensor-CASSY USB can be used mixed
  • fourfold electrically isolated (inputs A and B, relay R, voltage source S).
  • cascading of up to 8 CASSY modules possible (to multiply the inputs and outputs)
  • up to 8 analog inputs per Sensor-CASSY retrofittable using sensor boxes
  • automatic sensor box detection by CASSY Lab (524 200) - plug and play -
  • microprocessor-controlled via the CASSY operating system (complete with software update functionality for fast, easy performance enhancements)
  • can be set up as a benchtop, console or demonstration unit (also suitable for CPS/TPS panel frames)
  • voltage supply 12 V AC/DC via cannon plug or an adjacent CASSY module

Note: also available with USB port (524 010USB)

Technical Data
  • 5 analog inputs (any two inputs A and B usable simultaneously)
    2 analog voltage inputs A and B on 4-mm safety sockets
    Resolution: 12 bits
    Measuring ranges: ± 0,3/1/3/10/30/100 V
    Measurement error: ± 1 % plus 0.5 % of range end value
    Input resistance: 1 MΩ
    Scanning rate: max. 200,000 values/s (= 100,000 values/s per input)
    Number of measured values: nearly unlimited (depends on PC) up to 100 values/s, at higher measuring rate max. 32,000 values (= 16,000 values per input)
    1 analog current input A on 4-mm safety sockets
    Measuring ranges: ± 0.1/0.3/1/3 A
    Measurement error: voltage error plus 1 %
    Input resistance: < 0.5 Ω (except under overload)
    See voltage inputs for further data
    2 analog inputs at sensor box connector sites A and B
    (All CASSY sensor boxes and sensors can be connected)
    Measuring ranges: ± 0.003/0.01/0.03/0.1/0.3/1 V
    Input resistance: 10 kΩ
    See voltage inputs for further data
    The technical data will change according to a connected sensor box. In this case, the CASSY Lab automatically detects the possible measurement quantities and ranges when a sensor box is attached.
  • 4 timer inputs with 32-bit counters at sensor box site (e.g. for BMW box, GM box or timer box)
    Counting frequency: max. 100 kHz; time resolution: 0.25 µs
    Measuring time between two events at same input: min. 100 µs
    Measuring time between two events at different inputs: min. 0.25 µs
    Memory: max. 10,000 time points (= 2,500 values per input)
  • 1 changeover relay (with LED to indicate switching state)
    Range: max. 100 V / 2 A
  • 1 analog output (PWM-output) (pulse-width modulated, switchable voltage source, LED switching state indicator, e.g. for holding magnet or supplying the experiment)
    Variable voltage range: max. 16 V / 200 mA (load ≥ 80 Ω)
    PWM range: 0% (off), 5-95% (1% resolution), 100% (on)
    PWM frequency: 100 Hz
  • 12 digital inputs (TTL) on sensor box sites A and B (at present only used for automatic sensor box detection)
  • 6 digital outputs (TTL) on sensor box sites A and B (at present only used for automatic switching of the measuring range of a sensor box)
  • 1 serial interface RS232 (subD-9) for connection to a computer
  • 1 CASSY bus for connecting additional CASSY modules
  • Dimensions: 115 mm x 295 mm x 45 mm
  • Weight: 1 kg
