What it is and what it does
The 6ES7924-0BE10-0BB0 is a terminal block with an integrated relay, built for SIMATIC S7-300 and ET 200M distributed I/O systems. It takes a 230V AC coil signal and switches eight normally-open (NO) outputs rated at 24V DC, 0.05A each. The spring-cage terminals with LED indication make wiring and troubleshooting straightforward in a control cabinet.
Integration notes
The 16-pole IDC connector accepts flat ribbon cable, which keeps the wiring tidy when running multiple signals to a single I/O module. Spring terminals on the field side mean no screw-torque checks — strip to 8 mm, push the wire in, done. The LED on each output channel gives a quick visual on coil state, which saves time during commissioning or line-down fault-finding.
