ABB 1SAP180600R0001 - TA524 Dummy Communication Module (AC500)

The ABB 1SAP180600R0001 is the order code for the TA524, described by ABB as a dummy communication module (dummy coupler) for AC500 systems. In distributed I/O configurations, the dummy coupler occupies the bus position where no active communication processor is required, letting S500 I/O modules terminate correctly without an address-consuming coupler. Distributor listings record unit weight around 0.1 kg with pack dimensions 160 x 140 x 20 mm and show stock from specialist sellers. Match the exact order code against your system documentation before ordering to confirm the coupler position and backplane requirements of your configuration.
