It uses PROFIBUS and RS485, with a 55 °C maximum ambient and a derating of 3 K per 1 000 m above sea level. The IP20 enclosure is intended for clean, dry control cabinets — not washdown zones. For brewery CIP areas you'll need an upstream cabinet or IP65-rated remote I/O. But for the batch control panel itself, this unit handles the process signals: 4–20 mA from flow or pressure transmitters, temperature RTDs (via the analog inputs), and discrete actuator feedback through the digital inputs. The operating voltage range spans 20.4 to 28.8 VDC supplied either from the power module or an external 24 V supply. Current draw maxes at 0.5 A. If you're paralleling outputs, remember the package limit is the total; the analog outputs are 10-bit resolution, adequate for valve positioning but not fine metering. Max ambient temperature 55 °C, min -20 °C. Storage range -40 to 70 °C. IP20. PROFIBUS and RS485 present; no PROFINET. The fail-safe feature uses two standard digital inputs, but the unit itself is not a safety controller — it can monitor safety shutdowns. The integrated analog inputs can double as supplementary digital inputs if needed.","metaTitle":"Siemens 6AG1244-0BB12-2PA1 Control Unit, 55 °C max","metaDescription":"Siemens 6AG1244-0BB12-2PA1 control unit with 2 AI/2 AO, 6 DI, PROFIBUS RS485, 55 °C max, IP20.
