Siemens 6ES7922-3BC50-0AC0 SIMATIC TOP Connect Front Connector 40-Pole 2.5m PLC Connection Module

The Siemens SIMATIC TOP connect front connector 6ES7922-3BC50-0AC0 is a 40-pole, 40-channel pre-wired connector for SIMATIC S7-300 digital I/O modules, terminating in 40 single H05V-K cores of 0.5 mm² at 2.5 m length. It plugs directly onto the module in place of a standard front connector, rated 24V DC / 1.5A per core, with screw-type field termination.

Technical Specifications

Selection Notes

This front connector is a direct plug-in replacement for a standard S7-300 front connector, saving the labor of terminating 40 individual field wires by hand. Choose it when the 2.5 m length and 0.5 mm² cross-section match the field wiring already planned for the digital I/O module it connects to. At 1.5 A per core, pair it only with modules whose per-channel current stays at or below that rating.

Applications

Wires digital input or output modules of the SIMATIC S7-300 line to field devices via numbered single cores instead of a bare screw-terminal front connector, reducing wiring errors on panel builds using SIMATIC TOP connect.
