You bring 24 V DC to the backplane (tolerates down to L+ minus 1.5 V) and connect your dry contacts or transistor drivers to the inputs; the four outputs each handle up to 300 mA, though derate to 100 mA if the module is mounted vertically. Width is 35 mm; typical power loss 4.6 W. Shielded cable max. 1 000 m; unshielded 500 m. ## Diagnostics and safety integration The module reports a diagnostic alarm via backplane and has per-channel short-circuit detection. It is SIL 3 certified. Filters are configurable: minimum on/off time is 0.4 ms, maximum 20 ms, so you can reject contact bounce on mechanical limit switches or tighten the window for encoder-style signals.","metaTitle":"Siemens SIPLUS 6AG1526-1BH00-2AB0 DI/DO Module, 16DI 4DO, SI","metaDescription":"Active production 6AG1526-1BH00-2AB0 SIPLUS digital I/O module, 16 inputs 4 outputs 24V, diagnostic functions, SIL3.
