It connects the I/O module (X10 or X11) to a 32-channel connection module, carrying 40 conductors of 0.14 mm² cross-section for digital signal transmission. Rated at 24 V with a maximum of 60 V, this unshielded cable suits digital I/O modules in control cabinets where signal integrity over short distances is adequate without shielding. The 24 V rated value matches the standard control voltage for S7-1500 digital I/O modules, so this cable is a direct drop-in for 24 VDC field wiring. The 60 V maximum is the insulation rating — it handles transient peaks on the line without breakdown, but the intended signal level is 24 V. The 1 m length is fixed; if your panel layout requires a longer run between the I/O module and connection module, you need a different order code. The 0.14 mm² conductor cross-section is fine for digital signals at this distance — no voltage drop concern for 24 V logic levels. ## Deployment context In a control panel, this cable routes from the S7-1500 I/O module's front connector (X10 or X11) to the 32-channel connection module, which then breaks out to field terminals. The round cable sheath is PVC, black, 10.3 mm outer diameter — plan for a 16 mm or larger cable gland if passing through a panel plate. Operating temperature range is -30 to +60 °C, storage -30 to +70 °C, so it's fine for most indoor cabinet environments.","metaTitle":"Siemens 6ES7923-5BB00-0GB0 Pre-assembled Round Cable, 1 m, 4","metaDescription":"Siemens 6ES7923-5BB00-0GB0 pre-assembled round cable for SIMATIC S7-1500 digital I/O modules. 1 m length, 40-pole IDC connector, 0.14 mm² conductor, 60 V max.
