It carries 40 conductors on a 40-pole IDC connector at one end and a 50-pole connector at the connection module end, with a 2.5 m length of unshielded round cable. Rated for 24 V and a maximum of 60 V, it is intended for digital signal transmission only — not for analog signals. Each conductor is 0.14 mm², and the cable sheath is black PVC with a 10.3 mm outer diameter. The 24 V rated value matches the typical control voltage on S7-1500 digital I/O modules, so this cable is a direct fit for wiring 24 VDC sensors and actuators back to the connection module. The 60 V maximum means it can also handle 48 VDC signals if your field devices run at that voltage, but it is not rated for mains AC or higher-voltage analog loops. With 32 channels and 40 conductors, the cable supports a full 32-channel digital I/O module with spare conductors for shield or spare wiring. The 0.14 mm² conductor cross-section is fine for low-current digital signals (typically 0.5–2 A per channel on S7-1500 output modules) but undersized for any power distribution.","metaTitle":"Siemens 6ES7923-5BC50-0GB0 Pre-assembled Round Cable, 2.5m,","metaDescription":"Siemens SIMATIC S7-1500 pre-assembled round cable, 2.5 m, 40-pole IDC connector, 0.14 mm², for digital I/O modules.
