Pre-assembled shielded cable for S7-1500 I/O
The 6ES7923-5BE00-0DB0 is a pre-assembled round cable with braided shield, purpose-built for the SIMATIC S7-1500 platform, connecting a 50-pin front connector module on the I/O card to a 50-pin connection module in the cabinet. Rated at 24 V with a maximum of 60 V, it carries both digital and analog signals across 50 conductors of 0.14 mm² each, in a PVC sheath with an 11 mm outer diameter. The 4 m length suits typical cabinet-to-field wiring runs where the I/O rack sits near the marshalling panel.
The 24 V rated value is the nominal signal level the cable is designed for — standard for S7-1500 digital inputs and outputs. The 60 V maximum means it can also handle analog loops or low-voltage auxiliary circuits without exceeding the insulation rating. The 50-pin IDC connectors on both ends are keyed to the Siemens front connector module (cable side) and the connection module (enclosure side). This is a drop-in replacement for any S7-1500 I/O module that uses the 50-pin front connector interface. Braided shield covers mixed digital/analog signal bundles.
