Siemens 6ES7155-5AA01-0AB0 SIMATIC ET 200MP IM 155-5 PN ST PROFINET Remote I/O Interface Module

The Siemens SIMATIC ET 200MP IM 155-5 PN ST (6ES7155-5AA01-0AB0) is a PROFINET IO-Device interface module that connects up to 30 ET 200MP I/O modules to a PROFINET IO controller, with an integrated 2-port switch, IRT support down to 250us, and Media Redundancy Protocol (MRP) client capability. It supports up to 12 modules without an added power supply, or 30 with one.

Technical Specifications

Selection Notes

The integrated 14W power supply (backplane infeed) lets this IM host I/O modules directly without a separate power supply, and 3 permissible power segments extend that to 30 modules per station instead of the 12-module limit without an added supply. Shared Device support for up to 2 IO Controllers and PROFINET MRP client capability suit split-ownership or ring-topology PROFINET architectures; select a station design with an additional power supply only if the connected I/O modules draw more than the 14W the integrated supply provides.

Applications

Used to build distributed ET 200MP I/O stations on PROFINET for machine control, process skids, and panel-building applications needing IRT-capable I/O with switch-embedded ring or line network topology.
