Pre-assembled I/O cable for S7-1500
The Siemens 6ES7923-5BJ00-0DB0 is a pre-assembled shielded round cable purpose-built for SIMATIC S7-1500 systems. It connects the front connector module to a connection module using 50-pin IDC connectors on both ends, with a fixed length of 8 m. Rated at 24 V with a maximum of 60 V, this cable handles 32 channels and supports both digital and analog signal transmission — meaning a single cable run can serve mixed I/O modules without separate analog wiring. The round cable design uses 50 conductors of 0.14 mm² cross-section, a braided shield for noise immunity, and a black PVC sheath with an 11 mm outer diameter. It is suited for digital and analog I/O modules in the S7-1500 rack.
