ABB 129740-002 - Smart I/O Weight Module (SMART I/O SMART WEIGHT)

The ABB 129740-002 is an official ABB product described on ABB's own pages as SMART I/O - SMART WEIGHT, an intelligent input/output module used for weighing and tension measurement duties. Distributor and repair-depot listings consistently describe it as an SIO (smart I/O) assembly that connects mV weighing transducers and standard analog signals to ABB control platforms, with multiple sources associating it with the Advant Controller 400 family. Inputs listed by distributors include millivolt weighing signals plus 0-10 V and 4-20 mA standard loops. Because the full official datasheet was not located, channel counts, accuracy and supply requirements should be confirmed with the supplier before ordering.
