The Siemens 6ES7922-5BG50-0HC0 is a 40-pole front connector with pre-wired single cores, purpose-built for SIMATIC S7-1500 digital I/O modules. It terminates the field wiring to the module via a screw-type terminal block on the enclosure side, with a 6.5 m cable run of 0.5 mm² H05Z-K cores — halogen-free, numbered consecutively from 1 to 40 at the adapter end for straightforward panel termination.
Rated at 24 V with a maximum of 30 V — this is the voltage class for standard S7-1500 digital I/O signals. The 24 V rating matches the typical PLC backplane supply; the 30 V ceiling gives headroom for transient spikes without risking the module's input circuits. The 6.5 m cable length is a fixed assembly, so if your cabinet layout requires a longer or shorter run, you are looking at a different order code — no field splicing on this one.
This connector is designed exclusively for SIMATIC S7-1500 digital I/O modules — it is not rated for analog signal transmission, so keep it on discrete input/output cards. The screw-type terminal block on the module end accepts the 0.5 mm² cores; the cable sheath is blue RAL 5010, which matches the standard S7-1500 color coding for digital modules.
