ABB TB541-ETH 1SAP114100R0270 Terminal Base
The four-communication-slot Ethernet terminal base for an AC500 V2 processor station, with integrated serial, FieldBusPlug, supply and local I/O-bus connections.
Product Profile
TB541-ETH is the widest standard Ethernet terminal base in the AC500 V2 TB5x1 range. It carries one processor and up to four communication modules on a single base.
The base provides the Ethernet RJ45 connection for the matching processor, two serial interfaces, a FieldBusPlug interface, a 24 V DC supply terminal and the local S500 I/O-bus connection.

System Role
The four communication positions allow one AC500 processor station to carry a broader set of base-mounted communication modules than TB511-ETH or TB521-ETH. Protocol capability is determined by the modules installed in those positions.
The base also distributes the processor interfaces and extends the S500 I/O bus to adjacent local I/O terminal units.
Compatibility
- Select an AC500 V2 Ethernet processor approved for the TB5x1-ETH R0270 terminal-base generation.
- Keep the total number of communication modules within the four physical positions.
- Use the separate TB541-ETH-XC order code when the extended-condition system version is required.
- Match each communication module to the processor firmware and Automation Builder configuration.
- Check panel width because TB541-ETH has a documented 179.5 mm base length.
Applications
- AC500 V2 systems requiring as many as four communication modules at the CPU station.
- Multi-network controller panels with an Ethernet processor connection.
- Stations combining base-mounted communication with local S500 I/O expansion.
- Modernization work that retains an established AC500 V2 hardware architecture.
- Replacement projects where panel width, processor revision and all four module positions are documented.
FAQ
How many communication modules fit on TB541-ETH?
The base provides four communication-module positions plus one processor position.
What is the documented base length?
TB541-ETH has a length of 179.5 mm.
Does the base itself define the communication protocols?
No. Protocol behavior depends on the installed processor and communication modules.
Which network connector identifies the ETH version?
It uses an Ethernet RJ45 connector.
When should TB541-ETH-XC be considered?
Use the separate XC product when an approved extended-condition AC500-XC arrangement is required.
What should a replacement record include?
Include the processor order code, all communication modules, terminal-base code, network and serial wiring, I/O chain and panel-space constraints.
