Siemens 6ES7155-6AR00-0AN0 Interface Module

Siemens 6ES7155-6AR00-0AN0: SIMATIC ET 200SP IM 155-6PN Basic Interface Module

The Siemens 6ES7155-6AR00-0AN0 (IM 155-6PN Basic) is a cost-effective, reliable PROFINET interface module engineered for standard SIMATIC ET 200SP distributed I/O applications. Ideal for small-to-medium automation setups, this module links up to 12 local ET 200SP I/O modules directly to a central PLC over a PROFINET IO network.

Featuring an integrated 2-port RJ45 switch, the IM 155-6PN BA eliminates the need for an external BusAdapter, streamlining hardware costs and installation footprint while maintaining high operational performance.

Key Features and Industrial Benefits

Integrated 2-Port RJ45 Switch

Save space and reduce budget requirements. Unlike Standard or High Feature variants, the Basic module comes equipped with fixed, dual RJ45 ports integrated directly into the housing, enabling line topology networking without extra BusAdapter hardware.

Cost-Effective Distributed I/O

Perfect for compact control panels and machine designs requiring essential digital and analog I/O control without the higher cost of advanced network redundancy features.

Simple Setup & Integration

Seamlessly configure the module within TIA Portal or integrate it into non-Siemens engineering platforms using standard GSDML files.

Compact 35mm Design

The ultra-slim profile maximizes valuable space inside your electrical enclosure, allowing high-density panel layouts.

Applications

• Small-scale machine automation and standalone equipment

• Standard industrial control panels using S7-1200 or S7-1500 controllers

• HVAC control systems and auxiliary plant utility stations

• Basic conveyor systems and material handling setups
