It provides the wiring interface between field devices and the I/O module, with an infeed function to supply the module's load group. The enclosure is grey, sized 100 mm wide × 76 mm high × 60 mm deep, with a single terminal level at the top. Rated for 24 V DC (maximum 28.8 V DC) and 1 A per terminal, with a total current limit of 2 A across all terminals. This means the module can handle up to 2 A total load on its I/O circuits — enough for a bank of sensors or small actuators, but not for high-current outputs. The 40 terminals break out as 32 I/O points plus 4 each for L+ and M, so you get a full 32-channel digital I/O connection in one module. Maximum cable length between the front connector module and this connection module is 30 m — useful for remote I/O cabinets. ## Integration Notes No shield connection or PE connection on this module — grounding happens at the I/O module or cabinet level. The module includes an infeed function, so it can supply power to the connected I/O module's load group without an external distribution block. No end cover plate is required, and a 3.5 mm screwdriver blade is specified for the terminals.","metaTitle":"Siemens 6ES7924-2AK20-0BA0 Connection Module, SIMATIC S7-150","metaDescription":"Siemens 6ES7924-2AK20-0BA0 connection module for SIMATIC S7-1500 digital I/O.
