The Siemens 6ES7922-5BF00-0UB0 is a front connector with pre-terminated single cores, purpose-built for SIMATIC S7-1500 digital I/O modules. It mates to the 40-pole interface (order code 6ES7592-1AM00-0XB0) and brings out 20 individually numbered cores — one per channel — terminated in screw-type terminals on the enclosure side. The cable is 5 m long, 0.5 mm² per conductor, with a blue PVC sheath and a 2.2 mm outer diameter per bundled core.
Rated at 24 V with a maximum of 30 V — standard for S7-1500 digital signals. The 20 channels match a 20-point input or output module exactly; no spare conductors left unterminated. The 0.5 mm² cross-section is sized for the current draw of a typical digital I/O channel (well under 1 A per point) and keeps the bundle flexible enough for a 5 m cable run inside a cabinet or to a nearby junction box. Screw-type terminals on the module end mean a screwdriver termination — no special tooling needed for field wiring.
