It provides 22 screw terminals — 8 x O, 2 x L+, 2 x M, and 10 special terminals — in a single level, top-entry layout. Rated at 50 V and 1 A, it supports digital output modules and includes an infeed function for voltage distribution. Mounts on either 35 mm or 15 mm DIN rail, in any orientation except head-down. Screw terminals accept 0.5 to 2.5 mm² stranded wire; a 3.5 mm screwdriver blade is specified. Up to two wires per connection are allowed when the combined cross-section fits within a single ferrule. The module has no PE connection, no shield connection, and no disconnector. An end cover plate is not required. ## Electrical ratings and environment Rated current is 1 A; total current through the module must not exceed 32 A, with a per-group limit of 16 A for any four adjacent terminals. Maximum wire length between this module and the front connector is 30 m. Pollution degree 2, overvoltage category II.","metaTitle":"Siemens 6ES7924-0BF20-0BA0 Connection Module, 22 terminals,","metaDescription":"Siemens 6ES7924-0BF20-0BA0 connection module for SIMATIC S7-300/1500. 22 screw terminals, rated 50 V, 1 A.
