The SIMATIC ET 200SP IM 155-6 PN ST family is Siemens’ compact distributed I/O platform for PROFINET architectures. The 6ES7155-6AU01-0BN0 interface module provides deterministic cyclic I/O on PROFINET and supports flexible station expansion using ET 200SP and ET 200AL components—ideal for OEM machines, skids, and plant upgrades where footprint and modularity matter.
Typical applications:
- Distributed I/O drops for packaging, conveying, material handling, and process skids
- ET 200SP remote racks connected to S7 controllers over PROFINET
- Cabinet-friendly expansions where modular I/O density is required
- PROFINET interface module for ET 200SP distributed I/O
- Supports up to 32 ET 200SP I/O modules and up to 16 ET 200AL modules (per Siemens specifications)
- Integrated 2-port Ethernet switch for line topology installations
- 24 VDC supply
- Compact form factor suited for control cabinet installations
- 1 Year PLCExchange Warranty + 30 Days worry-free return from delivery
