The Siemens 6ES7922-5CB00-0AC0 is a 40-pole front connector with pre-wired single cores for SIMATIC S7-1500 digital I/O modules. It terminates at a screw-type terminal block on the module end and delivers 40 individual H05V-K 0.5 mm² cores, each numbered consecutively from 1 to 40, running 10 m to the field device. Rated 24 V with a maximum of 30 V, this is the cable assembly that bridges the I/O module to the junction box or marshalling cabinet.
The 40-pole count matches the S7-1500 digital I/O modules (both input and output cards) that use the 6ES7592-1AM00-0XB0 connector interface. The 30 V maximum and 24 V rated value align with standard 24 VDC control signals — this is not a power cable, it's a signal harness for discrete I/O. The 0.5 mm² conductor cross-section carries the typical 0.5 A per channel load without voltage drop over the 10 m run. The blue PVC sheath (RAL 5010) and numbered cores simplify tracing in a crowded cabinet.
