What it is and what it does
The Siemens 6ES7924-0AA10-0BA0 is a TP1 terminal block with 8 channels and 2x2 terminals dedicated to potential supply. It uses screw-type terminals for actuators and sensors, and a plug-in connection for the cable side. A built-in LED gives visual status indication on each channel. Rated at 60 V and 1 A, this block handles signal-level and low-power distribution within a control cabinet. The infeed function means one of the terminal pairs is designed to bring supply voltage into the block, which then distributes it across the other channels — a common arrangement for powering sensor rails or I/O modules without a separate distribution bar.
Mounting and integration
Snaps onto either 35 mm or 15 mm DIN rail, giving flexibility in panel layouts where space is tight. The enclosure is 63 mm long, 55 mm wide, and 43.2 mm high — a compact footprint that fits alongside standard terminal blocks in a crowded cabinet. Accepts stranded wire from 0.5 to 2.5 mm², with or without ferrule processing, so it works with typical control wiring. The single terminal level with top-entry position keeps wiring accessible and organized.
Lifecycle and sourcing
For a BOM line that calls out 6ES7924-0AA10-0BA0, the fit is confirmed by the 60 V / 1 A rating, the 8-channel count with integrated potential supply, and the screw-terminal / IDC hybrid connection. Quoted to order against an RFQ.
Environmental and compliance
Rated for operating temperatures from 0 to 60 °C, which covers most indoor cabinet environments. The enclosure material meets UL 94 V-1 flammability classification, so it is acceptable for use in equipment requiring flame-retardant components.
