Toshiba TBU268S 8-Slot Programmable Logic Controller Expansion Rack

The Toshiba TBU268S 8-Slot PLC Expansion Rack expands Toshiba T2/T2E Series PLC systems by providing eight I/O slots for additional modules, enabling larger-scale factory automation, process control, and OEM machinery deployments. This panel-mount expansion rack, MPN TBU268S (Alternate Part Number TBU268-S), accepts Toshiba T2/T2E Series I/O and Special Function Modules and is powered from the PLC basic unit, with two expansion connectors (input and output) for daisy-chain expansion to additional racks. The rack offers 8 module slots, seven of which are available when used as a basic rack, and is designed for distributed I/O configurations in manufacturing environments such as conveyors, packaging lines, material handling equipment, and process control panels. System integrators and maintenance teams rely on it to extend and retrofit Toshiba PLC-based control systems. Common replacements include BU268, BU266, and BU228N.
