The 24 V DC supply accepts 20.4 V to 28.8 V — wide enough to ride through brownouts on long refrigeration feeder runs. ## Panel fit and I/O budget for medium distributed systems Dimensions 90 mm wide, 100 mm high, 75 mm deep match the standard S7-1200 footprint — drops into existing cutouts without panel rework. 1024 bytes each of input and output image gives room for a medium-sized distributed I/O network over PROFINET. Integrated 1 Mbyte memory holds the program and data for complex sequences like defrost schedules and compressor staging. ## Programming and communication toolchain Supports FBD, LAD, and SCL — the full TIA Portal toolchain, so any Siemens-savvy integrator can pick up the project without retraining. PROFINET IO as server means it talks directly to a higher-level controller or SCADA over TCP/IP without a gateway. PID controller is built in — no separate loop module needed for temperature or pressure control on a freezer line. ## Regulatory acceptance and compliance documentation Carries cULus, CE, and UL approval — accepted in North American and European installations without additional certification work. Backup time 240 h typical retains the program and retentive data during a power loss, critical for maintaining defrost and alarm setpoints.","metaTitle":"Siemens 6AG1212-1HD30-5XB0 S7-1200 PLC, 24 V DC","metaDescription":"Siemens 6AG1212-1HD30-5XB0 S7-1200 PLC, 24 V DC supply, 20.4–28.8 V range, -40 to 70 °C operating, 1 MB memory, 1024 byte I/O, PROFINET IO server, cULus/CE/UL.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"FBD":"Yes","LAD":"Yes","SCL":"Yes","24 V":"Permissible range: 20.4V to 28.8V","Max.":"70 °C","Min.":"-40 °C","Depth":"75 mm","Width":"90 mm","cULus":"Yes","Height":"100 mm","Inputs":"1 024 byte","MODBUS":"No","TCP/IP":"Yes","24 V DC":"Yes","CE mark":"Yes","Forcing":"Yes","Outputs":"1 024 byte","Overall":"15; dynamically","Present":"Yes; Entire project maintenance-free in the integral EEPROM","Voltage":"Yes","Isolated":"Yes","PROFIBUS":"No","As Server":"Yes","Supported":"Yes","Variables":"Inputs/outputs, memory bits, DBs, distributed I/Os, timers, counters","0 to +10 V":"Yes","Adjustable":"Yes","Expandable":"No","Integrated":"1 Mbyte","Size, max.":"4 kbyte; Size of bit memory address area","Backup time":"240 h; Typical","UL approval":"Yes","AS-Interface":"No","Autocrossing":"Yes","Number, max.":"Limited only by RAM for code","2-Wire Sensor":"Yes","For Signal \"0\"":"5 V DC at 1 mA","For Signal \"1\"":"15 V DC at 2.5 mA","PID controller":"Yes","Shielded, Max.":"100 m; shielded, twisted pair","Autonegotiation":"Yes","Parameterizable":"Single phase: 3 @ 100 kHz & 1 @ 30 kHz, differential: 3 @ 80 kHz & 1 @ 30 kHz","Weight, approx.":"385 g","Without Battery":"Yes","lifecycle_stage":"current","\"0\" To \"1\", Max.":"10 ms; max.","\"1\" To \"0\", Max.":"10 ms; max.","Power loss, typ.":"9 W","RJ 45 (Ethernet)":"Yes","Rated value (DC)":"24 V","Unshielded, Max.":"150 m","Fall height, max.":"0.3 m; five times, in product package","Source/sink input":"Yes","Inputs, adjustable":"1 kbyte","On Lamp Load, Max.":"30 W with DC, 200 W with AC","At \"0\" To \"1\", Max.":"12.8 ms","At \"0\" To \"1\", Min.":"0.2 ms","Outputs, adjustable":"1 kbyte","Programming package":"STEP 7 Basic V10.5","Between The Channels":"No","For Signal \"1\", Typ.":"1 mA","ISO-on-TCP (RFC1006)":"Yes","Inrush current, max.":"12 A; at 28.8 V","Frequency measurement":"Yes","User-defined websites":"Yes","Controlled Positioning":"Yes","Number of alarm inputs":"4","PROFINET IO Controller":"Yes","Deviation per day, max.":"±60 s/month at 25 °C","Number of analog inputs":"2","Number of relay outputs":"6","Status/control variable":"Yes","For Bit Operations, Typ.":"0.1 µs; / Operation","Number of analog outputs":"0","Number of blocks (total)":"DBs, FCs, FBs, counters and timers.
