It provides 22 push-in terminals arranged as 8 x O, 2 x L+, 2 x M, and 10 special terminals, all on a single level at the top of the enclosure. Rated at 50 V and 1 A, the module supports stranded conductors from 0.2 to 2.5 mm² and mounts on 35 mm or 15 mm DIN rail. The push-in terminals accept a 3.5 mm screwdriver blade, and up to two wires per connection can be combined in a ferrule as long as the total cross-section stays within the terminal capacity. ## Terminal layout and infeed function The module includes an infeed function (voltage feed) that groups terminals into sets of four, each group limited to a maximum of 16 A. The total current through the module must not exceed 32 A, and overhead feeds are not permitted. No shield connection, PE connection, or disconnector is integrated. The enclosure is grey, rated for pollution degree 2 and overvoltage category II, with an operating temperature range of 0 to 60 °C and storage from -40 to +70 °C.","metaTitle":"Siemens 6ES7924-0BF20-0BC0 Connection Module, SIMATIC S7-300","metaDescription":"Siemens 6ES7924-0BF20-0BC0 connection module for SIMATIC S7-300/1500. 22 push-in terminals, rated 50 V / 1 A, 130x76x60 mm.
