ABB 1SAP112300R0277 TB523-2ETH is an AC500 terminal base for the PM591-2ETH CPU with two communication module slots, two Ethernet RJ45 interfaces and one RS-232 / RS-485 serial interface for modular industrial automation systems.
The ABB 1SAP112300R0277, type designation TB523-2ETH, is an AC500 terminal base specifically designed for use with the ABB PM591-2ETH CPU. It provides the mechanical mounting and electrical connection platform for the CPU and compatible communication modules, forming the foundation of a modular AC500 industrial automation system.
The TB523-2ETH provides 2 communication module slots and 2 Ethernet RJ45 interfaces, supporting the dual-Ethernet functionality of the PM591-2ETH. It also incorporates 1 serial interface supporting RS-232 / RS-485, providing an additional connection option for compatible industrial devices and communication networks.
Designed for modular control-panel installations, the TB523-2ETH also provides an I/O interface for direct connection of compatible AC500 expansion modules. With compact dimensions of 123.5 × 135 × 28 mm, IP20 protection and a net weight of approximately 0.173 kg, it provides a practical base for building PM591-2ETH-based machine and process automation systems.
The ABB TB523-2ETH acts as the mounting and connection platform for the PM591-2ETH CPU and compatible communication modules rather than functioning as a standalone PLC. Its two communication module positions allow the control system to be expanded with additional compatible communication functionality, while its I/O interface enables compatible AC500 expansion modules to be connected directly to the PLC system.
A defining feature of the TB523-2ETH is its provision for the PM591-2ETH CPU's dual Ethernet interfaces. Two RJ45 connections support Ethernet-based automation architectures, while the additional RS-232 / RS-485 serial interface accommodates compatible serial devices. This combination makes the terminal base suitable for modular AC500 systems requiring multiple communication paths within machinery and process-control installations.
