It is designed exclusively for SIMATIC S7-400 digital I/O modules — specifically the 48-pin strip connector 6ES7492-1AL00-0AA0 — and carries a 3.2 m multi-norm braided cable with a blue PVC sheath, 0.5 mm² conductor cross-section per core. The 46 channels map to digital signals only; analog transmission is not supported. ## Voltage ratings and wiring detail Rated at 24 V with a maximum of 30 V, this connector is sized for the 24 VDC control voltage typical of S7-400 digital I/O. The cores are numbered consecutively from 3 to 48, with the white adapter contact indicating the core number — a detail that matters when tracing field wiring back to the module. The screw-type terminal on the enclosure side accepts 0.5 mm² conductors (AWG 20), and the cable is UL/CSA AWM Style 1007/1569 FT2 TR64 rated.","metaTitle":"Siemens 6ES7922-4BD20-0UD0 Front Connector for S7-400, 3.2 m","metaDescription":"Siemens 6ES7922-4BD20-0UD0 front connector with 46 single cores, 3.2 m cable, screw-type terminals for SIMATIC S7-400 digital I/O modules.
