Siemens – 6ES7 193‑0CB10‑0XA0 + 6ES7 133‑0BN01‑0XB0 – 24DI/8DO Digital Module
This packaged set combines a Siemens ET 200B digital I/O assembly: a terminal block and its corresponding electronic digital I/O module. Designed for DIN-rail Profibus-DP systems, it provides 24 inputs and 8 outputs at 24 V DC. Both parts are discontinued (since Oct 1, 2017) but remain widely used in legacy automation systems.
