Structured mounting and field termination for documented ABB automation assemblies.
ABB TB511-ETH is an AC500 terminal base for mounting and connecting one processor module and one communication module. The base provides an integrated Ethernet RJ45 connection together with the AC500 station interfaces required for controller and I/O integration. A removable five-pole terminal block is used for the 24 V DC process-voltage connection, while the base can be installed horizontally or vertically. TB511-ETH supports controller assembly, cabinet construction and replacement of an identified installed base. Before ordering, verify the current order code, processor module, communication-module requirement, Ethernet connection, terminal wiring and overall assembly dimensions.
