The TS-RW82AC (134.2 kHz) is a modular read/write system that can be expanded from 4 to 32 antenna channels, thus saving costs as only one evaluation unit (TS-RW82AC-CPU) is required. Depending on the expansion stage, up to 8 antenna multiplexers (TS-RW82AC-MUX), each with 4 antenna channels, can be operated on one evaluation unit via a bus system.
