5850IA2CM3Y2BAA is a configured Brooks Instrument 5850i mass flow controller identifier in the Brooks 5800E elastomer-sealed mass-flow-controller/meter family. Official Brooks 5850i documentation describes a thermal mass flow controller with a flow sensor, integral control valve, and electronic control system, with selectable voltage/current command options, soft start, valve override, and 50:1 control range. Stored Sonisys auction records associate this exact configured identifier with carbon dioxide gas context, but full-scale range, calibration conditions, process connections, seal material, and configured options should be verified from the unit label or calibration paperwork
Unit-specific configuration
Observed configuration
Historical listing records identify this part as Carbon Dioxide. Exact gas, range, fittings, valve configuration, and communication interface must be verified from the physical unit label.
Configurations vary. Verify the exact unit before choosing a replacement.

Brooks Instrument 5850i mass flow controller in the 5800E elastomer-sealed mass-flow-controller/meter family
Configuration
Configured-unit rule
Gas, full-scale range, calibration conditions, process connection, seal material, signal option, and valve behavior vary by configured model code and physical unit label
Flow
5850i flow range context
5850i documentation covers low SCCM ranges through 30,000 SCCM nitrogen-equivalent context depending on calibration and configuration
Performance
5850i accuracy context
+/-1% full scale including linearity at calibrated conditions; +/-1.5% full scale including linearity for flow ranges greater than 20 SLM
5850i repeatability context
0.25% of rate
5850i control range context
50:1
Response time
Less than 6 seconds to within 2% of full-scale final value with a 0 to 100% command step
Pressure
Working pressure
1500 psi maximum
Allowable differential pressure
5 psi minimum and 50 psi maximum in the 5850i manual, with higher differential pressures configuration-dependent
Environmental
Operating ambient temperature
5 C to 65 C
Non-operating ambient temperature
-25 C to 100 C
Leak integrity
Helium leak integrity
1 x 10^-9 atm scc/sec helium
Mechanical
Standard gas connections
1/4 inch compression fittings standard; 1/8 inch compression, VCO, and VCR connections available by configuration
Electrical
Command input
Jumper-selectable 0-5 Vdc or 4-20 mAdc command input
Flow output
0-5 Vdc into 2,000 ohms or greater, with jumper-selectable 4-20 mAdc or 0-20 mAdc current output
Electrical connector
D-type 15-pin connector (DA-15P)
Power requirement
+15 to +28 Vdc, 245 mA at +15 Vdc to 370 mA at +28 Vdc
Controls
Valve behavior context
Integral control valve and control circuit; valve override can fully open or close the valve independent of setpoint
Soft start
Soft start slows introduction of process gas for processes that cannot tolerate rapid flow transition
Applications
Application domain
Semiconductor, laboratory, analytical, and process gas handling
Observed variants
Stored auction gas context
Stored Sonisys auction titles identify this exact configured identifier with carbon dioxide gas context across 2 tracked records; gas was not verified from official configured-part documentation
