What It Is and Where It Fits
The Siemens 6ES7924-1AA10-0AB0 is a connection module for the SIMATIC S7-1500 system — specifically a TPK module with 2x8 channels arranged as 2x2x2 terminals per channel, using spring-cage (push-in) terminations. It provides a potential supply infeed function, meaning it distributes a common voltage rail to the connected I/O modules without needing a separate terminal block. Rated at 60 V and 1 A, it handles the signal-level and auxiliary supply distribution inside the S7-1500 I/O rack.
Key Ratings and What They Mean for Fit
The 60 V rated value and 1 A current rating define the maximum continuous voltage and current the module can carry across its internal bus bars. For a potential supply module, this means it can feed up to 1 A of 60 V DC to the downstream I/O modules — enough for a bank of digital inputs or small-signal sensors, but not for powering actuators or solenoids directly. The spring-cage terminals accept stranded wire from 0.5 to 2.5 mm² (and finely stranded with core-end processing from 0.5 to 1.5 mm²), which covers standard control wiring sizes. The module mounts on either 35 mm or 15 mm DIN rail, so it fits both standard and compact enclosure profiles.
Integration Notes
The module has a single terminal level, with the connection position at the top. It requires no end cover plate, and it is not cross-connectable — each terminal point serves one wire. The enclosure is black, 80 mm long, 100 mm wide, and 43.2 mm high at its lowest-profile installation. Operating temperature range is 0 to 60 °C, and the insulation material carries a UL 94 V-1 flammability rating. There is no shield connection, no PE connection, and no disconnector built in — it is a straight-through potential distribution block.
