Features:
- One core model: R0270 and R0170 are documented order-number revisions of TB521-ETH.
- Module positions: The base provides one CPU position and two communication-module positions.
- Integrated connections: The current revision includes Ethernet and two configurable RS232/RS485 interfaces.
TB521-ETH is the ABB AC500 mounting and connection base for one CPU and two communication-module positions.
The two order numbers belong on one product page, while revision-specific weight and package data remain separately identified.
Before replacement, record the full order number, installed CPU, module sequence, cable destinations, terminal markings, and cabinet clearance.
The ABB TB521-ETH terminal base is available for quotation and revision-matching support from Apter Power, subject to current inventory and sourcing confirmation.
