It provides 40 screw-type terminals — 32 dedicated to I/O signals plus 4 for L+ and 4 for M — all on a single terminal level at the top of the module. Rated at 1 A per terminal with a 2 A total current limit, it handles the typical signal and small-load wiring for a digital I/O group. Mounts on either 35 mm or 15 mm DIN rail, in any position, with no end cover plate required. Screwdriver blade width of 3.5 mm matches standard terminal tools; the screw terminals accept stranded wire from 0.5 to 2.5 mm². Maximum cable length between the front connector module and this connection module is 30 m. ## Electrical and environmental ratings Rated for 24 V DC (maximum 28.8 V DC). Overvoltage category II, pollution degree 2. The enclosure material carries a UL 94 V-1 flammability rating. No integrated disconnector, no PE connection, and no shield connection — this is a pure wiring breakout module.","metaTitle":"Siemens 6ES7924-2AM20-0BA0 Connection Module, SIMATIC S7-150","metaDescription":"Siemens 6ES7924-2AM20-0BA0 connection module for SIMATIC S7-1500 digital I/O. 40 terminals (32 I/O, 4 L+, 4 M), rated 1 A per terminal, 2 A total.
