The 6ES7924-0BE10-0BA0 is a terminal block with an integrated relay, part of the Siemens S7-300 accessory line. It takes a 230V AC control signal on the coil side and switches eight normally-open (NO) outputs rated at 24V DC, 0.05A each. The screw terminals include an LED indicator, and the 16-pole IDC connector mates to a flat ribbon cable for the S7-300 backplane or I/O module connection.
The 230V AC coil is standard for European control panels running line-voltage pilot circuits. The 24V DC, 0.05A per output is a signal-level rating — it drives PLC inputs, indicator lamps, or small contactor coils, not motor loads. The 8 NO configuration gives you eight isolated dry contacts; the LED on each screw terminal confirms coil state at a glance during commissioning.
