It is designed specifically for digital I/O modules, not for analog signal transmission. The cable is unshielded, 10.0 m long, with a 50-conductor round design and a black PVC sheath of 10.3 mm outer diameter. Each conductor is 0.14 mm². It terminates in IDC connectors at both ends: a 16-pole connector on the cable side for the front connector module, and a 50-pole connector on the connection module side. Rated for 24 V and a maximum of 60 V — this matches the standard control voltage for S7-300/1500 digital I/O modules. The 60 V ceiling covers the 48 V nominal systems sometimes found in older installations, but the cable is intended for the 24 V digital I/O bus. With 32 channels and 50 conductors, this cable supports a full 32-channel digital I/O module plus spare conductors for commons or shields. The 0.14 mm² cross-section is adequate for signal-level currents (typically 10–20 mA per channel) but not for power distribution. This covers standard indoor control cabinet environments but not extended outdoor or high-heat applications. For a BOM line or a line-down replacement, the 6ES7923-5CB00-0EB0 is the correct, current cable for any S7-300 or S7-1500 digital I/O module that uses a 50-pin connection module. No cross-reference or substitute is needed — this is the active part.","metaTitle":"Siemens 6ES7923-5CB00-0EB0 Pre-assembled Round Cable, 10 m,","metaDescription":"Siemens 6ES7923-5CB00-0EB0 pre-assembled round cable, 10 m, 50-pin, 0.14 mm², for SIMATIC S7-300/1500 digital I/O modules.
