- Description
The Siemens 6ES7921-5CH20-0AA0 is a SIMATIC TOP connect front connector module with a 1x50-pole IDC connector, built for the digital 32-channel I/O modules of the S7-1500. It feeds potential (L+) to the terminal module through 4 Push-in terminals and replaces the standard front connector on the I/O module it wires.

Selection Notes
This connector module is a modified front connector for S7-1500 digital 32-channel I/O modules that need power fed in through 4 Push-in terminals rather than wired point-by-point at the module itself - pick it when the panel design routes potential distribution through SIMATIC TOP connect terminal modules instead of individual field wiring.
Applications
Used in panels built with the SIMATIC TOP connect fully modular wiring system to connect digital 32 I/O S7-1500 modules to pre-wired terminal blocks via a 50-pole IDC cable.
