What this terminal block does
The Siemens 6ES7924-0BB10-0AB0 is a TP2 terminal block with 8 channels, designed for 2A-digital output and 2x5 multiplication terminals. It uses a spring terminal design without LED and connects via a 16-pole IDC connector for cable. The infeed function is built in, meaning this block can serve as the power feed point for a row of terminals without needing a separate feed module.
Electrical and mechanical fit
