Siemens 6ES7924-0BE20-0BA0 SIMATIC TOP Connect TPRi 230V AC Relay Connection Module

The Siemens 6ES7924-0BE20-0BA0 is a SIMATIC TOP connect TPRi relay connection module that converts eight 230 V AC digital input signals to 24 V DC/0.05 A normally-open relay contacts for a SIMATIC S7-300/1500. Screw terminals with a status LED wire the field side, and a 16-pole IDC connector links the module to the front connector module on a 35 mm DIN rail.

Selection Notes

Each relay stage isolates a 230 V AC field signal from the 24 V DC input side, so this module belongs where the plant wiring runs mains voltage but the PLC input card only accepts 24 V DC. The relay’s 10,000,000-cycle mechanical and 3,000,000-cycle electrical endurance (at 230 V AC/50 mA/cos phi = 1) covers digital input duty but is not rated for continuous high-frequency switching, so keep the 8.33 operations/s ceiling in mind for fast-cycling signals. The yellow per-channel LED and green power LED let a technician confirm both the AC input state and the 24 V DC supply at the terminal block.
