The Siemens 6ES7922-5BF00-0AB0 is a pre-wired front connector for SIMATIC S7-1500 digital I/O modules. It comes with 20 individually numbered single cores (H05V-K, 0.5 mm², blue PVC sheath) terminated in a 40-pole screw-type connector block at the module end, with a 5 m flying-lead tail for field wiring. The 40-pole connector mates with the S7-1500 module's 40-pin receptacle (order code 6ES7592-1AM00-0XB0). The 20 cores are numbered 1 through 20, matching the terminal assignments on the I/O module — no guesswork during commissioning.
Rated for 24 V nominal with a maximum of 30 V, this connector is sized for the standard S7-1500 I/O module supply and signal levels. The 0.5 mm² conductor cross-section handles the typical 0.5–2 A per channel load of digital inputs and sourcing outputs without excessive voltage drop over the 5 m run. The screw-type terminal block on the module end accepts solid or ferruled stranded wire up to the listed cross-section. For field-side termination, the single cores can be landed in a DIN-rail terminal block or directly on field devices — the 5 m length gives enough reach for most cabinet layouts without a junction box.
