It provides 8 relay outputs, each rated at 1 A and 24 VDC, with normally open (NO) single contacts. The module uses screw-type terminals on a single level, accepting 0.5 to 2.5 mm² stranded wire, and mounts on standard 35 mm or 15 mm DIN rail. The grey enclosure measures 100 mm wide, 76 mm high, and 60 mm deep. The module mounts on DIN rail (35 mm or 15 mm) in any position. It has 20 terminals: 8 outputs (each with two terminals), 2 for L+, and 2 for M. The maximum wire length between the front connector module and this connection module is 30 m. No shield connection, PE connection, or end cover plate is required. Use a 3.5 mm screwdriver blade for the screw terminals. The module includes an infeed function for supplying power to downstream modules. Maximum switching frequency is 0.1 operations per second.","metaTitle":"Siemens 6ES7924-0BD20-0BA0 Connection Module, 8 Relay Output","metaDescription":"Siemens 6ES7924-0BD20-0BA0 connection module for SIMATIC S7-300/1500. 8 relay outputs, 1 A rated, 24 VDC.
