Technical Specs

  • Type
    Mass Flow Controller Module
  • ADC Native Resolution
  • Auxiliary Power Supply
    24V ±5%, This input will be used to power MFCs connected through IO connector. Each power output to MFC should be protected separately.
  • Power Consumption
    Assuming each MFC consumes 250 mA and all AOs are fully loaded ≥24 V_IO@1.5 Amp, 24 V_CORE@ 0.15 Amp
  • Anti-alias HW Filtering
    200Hz ±20%, 6dB/octave minimum
  • Connector
    9 pin D-sub
  • Analog Input Minimum Input CMRR
    50dB, 0-1kHz
  • Analog Input Maximum Integral Non-linearity
    ±2LSB (14-bit @ 14v)
  • Analog Input Number of AO Channels
    16, Single Ended, (4 for each MFC: Valve test point, Flow signal output, Optional input, Pressure output)
  • Analog Input Voltage Range
    -2V to 14V
  • Analog Input Maximum Error Over Full Range
    ±0.05% of Full Scale (over 20°C - 30°C)
  • Analog Input Sampling Rate
    6.25 kHz (160µSec , for all 16 channels) (ADC oversampling is set to x32)
  • Analog Input Protection
    ESD to IEC 61000-4-2 ±4kV contact, short to 24V, +15V, or -15V
  • Analog Output Number of AO Channels
    4 Single Ended (1 for each MFC: Set Point Input)
  • Analog Output DAC Native Resolution
  • Analog Output Maximum Output Current
    5mA, into a 2kOhm, 10nF load
  • Analog Output Output Accuracy at 25°C Ambient
    ±0.1% of Full Scale @5v, ±0.05% of Full Scale @10v
  • Analog Output Settling Time
    ±2.5mV in 1msec into 2kOhm, 10nF load
  • Analog Output Protection
    ESD to IEC 61000-4-2 ±4kV contact, short to 24V, +15V, or -15V
  • Digital Output Maximum Voltage Drop when ON
    0.2V into 30 kOhm Impedance
  • Digital Output Number of DO Channels
    12 (3 for each MFC: valve open, valve close, flow zero)
  • Digital Output Maximum Leakage Current OFF
    30 µA
  • Digital Output Minimum available current ON
    6 mA
  • Digital Output Protection
    5V TVS, resettable Fuse (25 mA PTC)
  • Logic Level
    5V TTL tri state DO for valve override function, Active HIGH and LOW, HIGH opens MFC control valve, Low closes the valve and floating allows for set point to control, 5V TTL Active Low for valve close, Valve open or Flow zero functions referenced to signal ground
  • Minimum Input Impedance
    150 kOhm
  • Timing
    Valve override 100 msec + response time (Digital Output)
