The Siemens 6ES7923-0BC50-0CB0 is a pre-assembled unshielded round cable purpose-built for connecting digital I/O modules on SIMATIC S7-300 and S7-1500 systems. It bridges the front connector module on the PLC rack to a remote connection module using IDC connectors at both ends. Rated at 24 V with a maximum of 60 V, this cable handles the signal-level voltages typical of digital input and output cards. The 16-pole, 8-channel design matches the channel count of standard 8-channel digital I/O modules, so one cable per module is the expected fit. The 2.5 m length gives enough reach to route from the rack to a nearby connection module inside the same cabinet without excessive slack. The 0.14 mm² conductor cross-section is sized for signal-level currents, not power delivery.
