Marine-Grade PLC for Extreme Temperature Environments
The 6AG1215-1AG31-5XB0 is a SIPLUS variant of the Siemens S7-1200 controller, rated for ambient temperatures from -40 to 70°C. That low-end rating is critical for cold-start on deck machinery or unheated equipment rooms where a standard industrial PLC would fail to power on. The unit operates on 24 VDC and provides a PROFINET interface for real-time fieldbus connectivity. Programming options include FBD, LAD, and SCL, matching the standard S7-1200 software suite.
Key Ratings and Capabilities
Input and output address areas are each 1 024 bytes. The unit includes 4 Mbyte of integrated working memory with a typical backup time of 480 h. The unit also supports PID controller functionality and can serve as a Profinet IO client or server. The maximum shielded cable length for PROFINET is 100 m.
