It connects the module's 40-pin front-connector receptacle (6ES7392-1AM00-0AA0) to field wiring via a 3.2 m multi-conductor cable, terminated at the module end with a screw-type terminal block. Rated for 24 V nominal and 30 V maximum, it handles the signal-level voltages typical of S7-300 digital inputs and outputs. The 30 V maximum and 24 V rated value match the S7-300 digital I/O bus voltage — 24 VDC nominal, with margin for transients up to 30 V. The 3.2 m cable length gives you enough reach from the DIN-rail mounted module to a nearby terminal strip or junction box without needing a splice. Each of the 40 cores is numbered consecutively (1 to 40) at both ends, with a white adapter marking the core number on the connector side, so you can trace field wiring back to the module channel without a toner. The screw-type terminal block on the module end accepts 0.5 mm² conductors (AWG 20), which is the standard wire size for S7-300 digital I/O field wiring in most panels. ## Cable construction and deployment context The cable is a multi-norm braid design with a blue PVC sheath (RAL 5010), each core 0.5 mm² and 2.2 mm outer diameter. It supports both digital signal transmission and analog signal transmission — though the connector is specified for digital I/O modules, the individual cores can carry analog signals if needed. The cable is UL/CSA AWM Style 1007/1569 FT2 TR64 rated, so it passes the vertical flame test for equipment wiring inside a panel. The PVC jacket and braid construction make it suitable for fixed installation in control cabinets where the cable is routed through cable ducts or tied to the panel backplane.","metaTitle":"Siemens 6ES7922-3BD20-0UC0 Front Connector, 40-Pole, 3.2m, f","metaDescription":"Siemens 6ES7922-3BD20-0UC0 front connector with 40 single cores, 3.2 m cable, screw-type terminals for SIMATIC S7-300 digital I/O modules.
