Siemens 6ES7924-2CA20-0BC0 SIMATIC TOP Connect TP3 32-Channel Push-In LED PLC Connection Module

The Siemens 6ES7924-2CA20-0BC0 is a SIMATIC TOP connect TP3 connection module with 32 channels and a 3-wire potential connection using push-in terminals with LED status indication, built for wiring SIMATIC S7-1500 digital I/O modules. It runs at 24 V DC (max 28.8 V) with up to 1 A per pin and 2 A total current, and carries ATEX, IECEx and UKEX hazardous-area ratings.

Selection Notes

Push-in terminals combined with the per-channel LED give both fast wiring and at-a-glance diagnostics, at 0.34 kg versus 0.54 kg for the screw-terminal LED sibling since push-in hardware is lighter. LED signaling caps the supply at 28.8 V DC against 50 V DC on the non-LED TP3 variants, so confirm downstream loop voltage stays in range. The 33+33 L+/M terminal layout gives each of the 32 channels its own switched potential line rather than a shared rail, unlike the TP1 module's single shared potential connection.

Applications

Fully modular field wiring with local channel diagnostics for SIMATIC S7-1500 digital I/O where each channel needs its own switched potential line, including ATEX/IECEx/UKEX Zone 2 areas.
