Bettico 16 Channel Sensor Signal Interface

General Features of the Bettico 16 Channel Sensor Signal Interface

  • 12 volt DC powered, reverse connection protected
  • Provides two 40-pin IDC Ribbon cable headers for connection to A to D adapter
  • Provides one 40-pin IDC Ribbon cable header featuring 16 conditioned analog voltage signals proportional to sensor signals for connection to an analog input device such as a stand alone-strip chart recorder
  • 16 sensor input channels, configured for customer requirements – typically 8 analog and 8 rate channels, 4/12 and 6/10 variations immediately available
  • Features of each analog sensor input channel:
    1. Accepts 4 to 20 milliamp sensor signal, current source or current sink
    2. Provides 24 volts transmitter excitation power, current limited
    3. Provides RFI and EMI filtering
    4. Provides conditioned, zero-offset 4 to 20 milliamp repeater signal outputs for connecting additional devices
    5. Provides front panel sensor zero control
    6. Provides front panel log/calibrate selection switch to allow operator to simulate zero and full scale sensor conditions in the calibrate position or real sensor signals in the log position
    7. Provides precision 4 and 20 milliamp reference signals for calibration purposes via a front panel lo-cal/hi-cal selection switch
  • Features of each frequency sensor input channel:
    1. Accepts 0 to 2,000 pulses-per-second (Hz) input signals
    2. Provides two-wire RFI and EMI filtering
    3. Provides differential noise canceling
    4. Provides both power supply and optical signal isolation between the sensor and the system to prevent interference between systems connected to a sensor
    5. Provides conditioned pulse type repeater signal outputs for connecting additional devices
    6. Provides front panel log/calibrate selection switch to allow operator to simulate zero and full scale sensor conditions in the calibrate position or real sensor signals in the log position
    7. Provides precision low (0 Hz) and up to 2,000 Hz reference signals for calibration purposes via a front panel lo-out/hi-in calibration/level selection switch. The “hi” reference signal value is determined by the setting of 4 front panel digital selector switches that allow the operator to simulate practically any full-scale process value sensor signal frequency. (Frequency = 250,000/switches’ value)
    8. Provides signal level discrimination selection via the front panel lo-out/hi-in calibration/level selection switch. The lo-out position is for tach generator signals and discriminates against low level signals while the hi-in position engages a high gain amplifier to allow detection of magnetic pickup level signals.
