Siemens 6ES7924-0AA20-0AA0 SIMATIC TOP Connect TP1 8-Channel PLC Connection Module

The Siemens 6ES7924-0AA20-0AA0 is a TP1 connection module for SIMATIC S7-300/1500 digital I/O, providing 8 signal channels plus a 2x2-terminal potential (L+/M) supply block with screw terminals and no LED. It connects to the module side over a 16-pole IDC cable up to 30 m long, part of the fully modular SIMATIC TOP connect wiring system.

Selection Notes

The TP1 module combines 8 I/O channels with a dedicated 2x2-terminal L+/M supply block, so field wiring and 24 V distribution share one DIN-rail unit instead of separate terminal strips. Screw terminals take 0.5-2.5 mm² conductors directly at the cabinet, while the 16-pole IDC connector on the module side links back to the front connector over cable runs up to 30 m — useful when the PLC rack sits away from the field terminals. The 4 A total current rating caps how much load can be summed across the shared supply block.

Applications

DIN-rail terminal interface for SIMATIC S7-300/1500 digital I/O modules using the fully modular SIMATIC TOP connect wiring system, mounted near field devices such as sensors, valves, and relays.
