Siemens 6ES7924-2CA20-0AC0 SIMATIC TOP Connect TP3 32-Channel Push-In PLC Connection Module

The Siemens SIMATIC TOP connect TP3 connection module 6ES7924-2CA20-0AC0 provides 32 push-in channels with dual 33-terminal potential rails for L+ and M, rated 24V DC (max 50V) at up to 1A per channel and 2A total. It is ATEX, IECEx, UKEX, and cULus certified for hazardous-location wiring and terminates a 50-pole IDC connecting cable up to 30m to the front connector module.

Selection Notes

The push-in, no-LED variant trades the plug-in visual channel diagnostics of LED versions for a flatter terminal block and lower per-channel cost — pick an LED version instead when field technicians need at-a-glance channel status without a multimeter. With ATEX, IECEx, UKEX, and cULus certification built in, this is the module to specify when the connection point itself sits inside a hazardous-area cabinet, not just the I/O module it feeds. The 1A-per-pin / 2A-total ceiling caps how many simultaneously active field devices one module can serve — check that against channel allocation on high-duty-cycle machines.

Applications

Terminates field wiring for SIMATIC S7-1500 digital I/O modules in hazardous-area or Ex-zone panel builds, connecting to the module's front connector via a 50-pole IDC cable up to 30m away — useful when the connection point needs to sit apart from the I/O module itself.
