5850S/BC1BA1ID0AA1B1
Brooks Instrument Profibus Smart Mass Flow Controller
About this part
5850S/BC1BA1ID0AA1B1 is a configured Brooks Instrument 5850S Smart Mass Flow Controller. Stored auction and marketplace evidence repeatedly identifies this specific code as a Profibus mass flow controller, most often with Air, plus observed Oxygen and Oxygen/CO2 title contexts. Official Brooks 5800S and Profibus-DP documents apply to the 5850S Smart Mass Flow controller family, while the exact gas/range and configured build options must be verified from the individual unit label or calibration record
Configurations vary. Verify the exact unit before choosing a replacement.

Specifications
Identification
| Device type | Smart-Series digital thermal mass flow controller |
| Series family | 5800S Smart Mass Flow Series |
| Configured code | 5850S/BC1BA1ID0AA1B1 |
| Observed interface | Profibus / Profibus-DP wording appears repeatedly in stored and marketplace title evidence |
| Official covered controller models | Brooks Profibus-DP documentation covers 5850S, 5851S, and 5853S mass flow controller models |
Configuration
| Configured-unit rule | Gas, full-scale range, fitting, valve state, connector, output/input package, and seal package vary by configured model code |
Flow
| 5850S/BC flow range context | The 5850S/BC base-model family is listed for 0.008 to 30 ln/min nitrogen-equivalent full-scale ranges |
Performance
| Accuracy | +/-0.7% of rate and +/-0.2% full scale at calibration conditions; optional +/-0.5% of rate and +/-0.1% full scale |
| Repeatability | +/-0.25% of rate |
| Rangeability | 50:1 within specified accuracy |
| Controller settling time | Standard 1 second settling time, with response up to 0.2 seconds possible depending on configuration |
Pressure
| Pressure rating | 5850S / 5860S are listed at 100 bar, with 300 bar high-pressure version optional |
Environmental
| Temperature range | Ambient and process gas: 0 C to 70 C |
Materials
| Wetted materials | Stainless steel wetted parts with configured elastomer or valve-seat material options |
Mechanical
| Main electrical connector | 15-pin D-type connector on Smart Mass Flow devices for analog operation |
Profibus
| Network connector | Profibus-DP interface uses a separate female 9-pin sub-D connector on the piggyback board |
| Network speed | Profibus-DP communication supports speeds up to 12 Mbit/sec |
| Analog coexistence | Smart Mass Flow Profibus products retain simultaneously available analog I/O signals |
Electrical
| Setpoint input | 0-5 VDC or 1-5 VDC voltage input, or 0-20 mA / 4-20 mA current input depending on configuration |
| Analog output | 0-5 VDC, 1-5 VDC, 0-20 mA, or 4-20 mA flow output adjustable by software depending on configuration |
| Controller power | +15 to +28 VDC or +/-15 VDC depending on configuration; +24 VDC required for normally open valves and 5851S use |
Controls
| Digital data availability | Flow, setpoint, flow totalizer, ambient temperature, operational settings, calibration data, controller settings, and PID settings are available through Smart-Series digital communication |
| Calibration storage | Storage of up to 10 calibration curves |
| Diagnostics | Self-diagnostics can activate an alarm output and expose failure details through digital communication |
Applications
| Application domain | Semiconductor, laboratory, analytical, and process gas handling |
Observed variants
| Stored auction gas/range combinations | Observed titles for this exact code include Air, Oxygen, and Oxygen/CO2 contexts; one marketplace listing identifies Oxygen 50 SCCM |
