Siemens 6ES7924-2AA20-0BA0 SIMATIC TOP Connect TP1 32-Channel Screw LED PLC Connection Module

The Siemens 6ES7924-2AA20-0BA0 is a SIMATIC TOP connect TP1 connection module with 32 channels and screw 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

The per-channel yellow LED plus a green power-OK LED let a technician read I/O state and supply health directly at the terminal block, which speeds fault-finding on a fully wired S7-1500 digital I/O rack. LED signaling narrows the maximum supply voltage to 28.8 V DC against the 50 V DC ceiling on the non-LED sibling, so check downstream loop voltage before substituting it in. Screw terminals rated at 0.4-0.5 N.m suit panels where wiring gets re-torqued during maintenance; choose the push-in LED variant instead where wiring speed matters more than torque-checked connections.

Applications

Fully modular field wiring with local channel diagnostics for SIMATIC S7-1500 digital I/O in machine and process control panels, including ATEX/IECEx/UKEX Zone 2 hazardous areas.
