ABB PM581-ETH 1SAP140100R0170 is an evidence-bounded AC500 Ethernet CPU module. ABB catalogs map PM581-ETH exactly to 1SAP140100R0170 and identify a 256 kB, 24 VDC CPU with integrated Ethernet.
- Exact model: PM581-ETH
- ABB order number: 1SAP140100R0170
- Program memory: 256 kB
- Process supply: 24 VDC
System role: It executes AC500 control applications and provides integrated Ethernet communication in the documented terminal-base architecture. Only facts stated by the cited ABB material are published; sibling, successor and third-party data are not transferred. Architecture boundary: Verify the exact TB521-ETH base, firmware, communication settings, I/O configuration and migration plan before replacement. ABB catalog editions publish different instruction-cycle figures, so this page does not present one edition's timing as a universal rating. Before installation or replacement, verify the complete physical label, host equipment, companion hardware, wiring and approved commissioning procedure. Origin and HS code remain unpublished unless an exact manufacturer record or the physical package label establishes them.
Important Notice: Verify the complete ABB PM581-ETH 1SAP140100R0170 physical label and installed-system documentation before use.
