It mounts on standard 35 mm or 15 mm DIN rail, so it integrates into the same enclosure as the CPU and power supply. Rated at 50 V and 1 A, it handles the signal-level switching typical of 24 VDC digital inputs — think proximity sensors, limit switches, or pushbutton panels wired back to the PLC. The 20 terminals break out as 8 pairs of inputs (8 x I x 2) plus two each for L+ and M. That gives you eight digital input channels with a common return — enough for a small machine zone or a section of a conveyor line. Screw-type terminals accept stranded wire from 0.5 to 2.5 mm², and the maximum cable run between the front connector and this module is 30 m. That matters if you're distributing I/O across a large panel or to a remote junction box.","metaTitle":"Siemens 6ES7924-0BG20-0BA0 Connection Module, 50 V, 1 A, DIN","metaDescription":"Siemens SIMATIC S7-300/1500 connection module for digital input signals.
