Type
Mass Flow Controller Module
ADC Native Resolution
14-bit
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
15 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
14-bit
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 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)
Operating Temperature
0 - 55°C
