Product Overview
The Siemens 6AG2155-5AA01-4AB0 is a PROFINET IO device interface module derived from the standard 6ES7155-5AA01-0AB0 base model. It incorporates specialized enhancements for extreme operational environments.
This specific variant includes conformal coating protection and supports operating temperatures ranging from -40 to +70 degrees Celsius. It also accommodates overtemperature class OT4 with ST1/2 ratings.
Technical Review Notes
- The module functions as a central interface for ET 200MP electronic modules within distributed automation architectures. It enables robust communication via PROFINET IO protocols.
- Physical dimensions are recorded at 15.4 x 14.9 x 4.3 cm with a net weight of 0.312 Kg. These metrics assist in rack space planning and handling logistics.
- An integrated two-port switch facilitates network connectivity, supporting RJ45 shared device connections. This design simplifies cabling infrastructure for connected peripheral devices.
- The interface supports Multiple Registration Protocol (MRP) for ring topology redundancy. Isochronous mode firmware updates ensure precise synchronization for high-performance motion control applications.
- Configuration data storage includes support for I&M0 through I&M3 functions. These identifiers aid in asset management and device identification within complex network structures.
- The system allows connection of up to twelve I/O modules without a power supply. With an additional power supply unit, capacity extends to thirty modules.
Model Identification
- The part number 6AG2155-5AA01-4AB0 identifies the SIPLUS extreme version of the IM 155-5 PN ST TX RAIL.
- This designation distinguishes the coated unit from the standard industrial grade counterpart found in typical catalog listings.
- The suffix indicates specific environmental hardening features required for deployment in challenging industrial settings.
- Review the submitted model against project documentation to confirm alignment with extreme condition requirements.
