What It Is and Where It Fits
The 6ES7924-0CC10-0AA0 is a 3-tier terminal block designed for analog SIMATIC S7 modules, using screw-type connections on the actuator/sensor side and a 16-pole IDC plug-in connection for the cable side. It carries a rated current of 1 A at 60 V, which means it handles the signal-level loads typical of analog I/O — not power distribution, but the low-current loop or voltage signals from transmitters, transducers, and field instruments. It mounts on either 35 mm or 15 mm DIN rail, so it fits standard enclosure profiles as well as the narrower rail found in some compact S7 backplane assemblies. The single terminal level per tier keeps wiring tidy for one signal per channel, and the black enclosure with V-0 flammability rating (UL 94 V1) meets the fire-safety requirements for panel-mounted equipment in industrial control cabinets.
Key Ratings and What They Mean for Fit
The 1 A / 60 V rating is the contact limit per terminal point — adequate for 4-20 mA loops, thermocouple signals, RTD inputs, and 0-10 V analog outputs. The stranded wire range of 0.5 to 2.5 mm² (with or without ferrule) covers the typical field-wiring gauges for analog signals; the IDC cable connection accepts the same range for the ribbon or multi-conductor cable to the module. Operating temperature from 0 to 60 °C keeps it within the ambient limits of a ventilated enclosure; derating is not required within that band. The infeed function means this block can accept the module's supply voltage feed-through — a detail that matters when planning the power distribution for the analog row. No PE connection and no shield connection means the block does not provide a dedicated protective-earth or cable-shield termination point; those must be handled separately on the DIN-rail ground bus or a shielded terminal.
