5850IA2CM342BEA is a configured Brooks Instrument 5850i thermal mass flow controller identifier. Official Brooks 5850i documentation describes the 5850i as a mass flow controller with a thermal flow sensor, integral control valve, electronic control system, valve override, soft-start behavior, voltage/current command options, and 50:1 control range. Stored auction records and exact listing records associate this configured code with high-flow gas service, including mixture 30 SLPM and other observed listing claims; the physical label and calibration paperwork should be used to confirm the exact gas, range, fittings, and calibration
Unit-specific configuration
Observed configuration
Historical listing records identify this part as Mixture at 30 SLPM. 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.

Flow
Flow range family context
Brooks 5850i documentation covers low SCCM ranges through 30,000 sccm nitrogen-equivalent / 30 SLPM high-flow configurations depending on calibration and model code
Measuring principle
Thermal mass flow sensing with closed-loop control valve regulation
Performance
Accuracy context
+/-1% full scale including linearity at calibrated conditions; +/-1.5% full scale including linearity for flow ranges greater than 20 SLPM
Repeatability
0.25% of rate
Control range
50:1
Response time
Less than 6 seconds to within 2% of full-scale final value with a 0-100% 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 to 65 C
Non-operating ambient temperature
-25 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
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/range combinations
Stored Sonisys auction titles repeatedly describe this configured code as a Brooks 5850i mass flow controller for mixture service at 30 SLPM
Configuration
Configured-unit rule
Gas, full-scale range, fitting, valve state, connector, and seal package are configured-unit attributes; confirm the exact values from the unit label or calibration documentation
