The Siemens 6ES7922-4BF00-0UD0 is a 48-pole front connector with 46 single cores, purpose-built for SIMATIC S7-400 digital I/O modules. It terminates field wiring to the module via screw-type terminals, carrying signals rated at 24 V (maximum 30 V) over a 5-meter multi-norm braided cable. The 0.5 mm² conductor cross-section suits standard digital signals — no analog transmission here.
This connector mates with the 48-pin receptacle on S7-400 I/O modules (e.g., 6ES7492-1AL00-0AA0). The 46 cores are numbered consecutively from 3 to 48, matching the module's channel assignment. Operating temperature range is 0 to 60 °C, storage from -30 to +70 °C.
