It gives you 40 terminals total — 32 for I/O signals plus 4 each for L+ and M — all in a single-level top-entry block that takes push-in terminations for stranded wire from 0.2 to 2.5 mm². That push-in style means no screwdriver needed for solid or ferruled stranded; you just strip to about 8 mm and push. The module itself measures 100 mm wide by 76 mm high by 60 mm deep and clips onto standard 35 mm DIN rail (also fits 15 mm rail). Each terminal is rated for 1 A continuous at 24 V DC, with a total current limit of 2 A across the module. That 1 A per terminal is enough for standard digital inputs (sensors, limit switches) and outputs (relays, small solenoids) — but if you're grouping multiple outputs on adjacent terminals, watch the 2 A total. The module includes an infeed function, so you can feed 24 V DC to the I/O modules through this block rather than running separate power wiring. Operating temperature range is -30 to +60 °C, storage from -40 to +70 °C, with pollution degree 2 and overvoltage category II — typical for a clean, dry control cabinet. Mounts in any position on DIN rail — no end cover plate required. The top-entry terminal arrangement keeps wiring accessible even in tight enclosures. Maximum wire length between this module and the front connector on the I/O module is 30 m, which covers most cabinet-to-field distances. The push-in terminals accept up to two wires per connection when using ferrules, as long as the combined cross-section stays within the ferrule limit. No shield connection or PE connection on this module — shield grounding happens at the I/O module or field device side. Flammability rating is UL 94 V-1.","metaTitle":"Siemens 6ES7924-2AM20-0BC0 Connection Module, 40 terminals,","metaDescription":"Siemens SIMATIC S7-1500 connection module, 40 terminals (32 I/O + 4 L+ + 4 M), push-in termination, 1 A rated, 24 V DC, DIN rail mount, mature lifecycle.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["PLC Accessories"],"specifications":{"title":"6ES7924-2AM20-0BC0","Length":"76 mm","Stranded":"0.2 ... 2.5 mm²","Rated Value":"24 V","description":"Connection module TP1 M signal 32 channels a. 4x2 terminals f.
