Description
About the Fully modular connection
About the Fully modular connection
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.

| marketing text | The TP3 connection module for a 3-wire connection with 32 channels and potential connection with push-in terminals without LED for signalling forms the interface between the connecting cables of the peripherals brought in from the field and the SIMATIC S7. This is mounted on the DIN rail and, thanks to its functionality with push-in terminals, is precisely adapted to the respective task. This connection module is part of the fully modular SIMATIC TOP connect connection for the fastest and safest system cabling. In addition to low wiring costs, error sources in cabling can be significantly reduced. Sensors and actuators from the peripherals are combined with the connection modules of SIMATIC TOP connect and connected to the SIMATIC S7-300/1500 via cable and front plug-in module. |
