It runs on a 24 V DC rated supply and dissipates 4.7 W typical power loss, which sets the thermal budget for the adjacent slot in the rack. The module accepts both source and sink input wiring — the signal thresholds are defined as -5 to +5 V for logic 0 and -11 to -30 V or +11 to +30 V for logic 1, referenced to COM. This means it can interface with PNP or NPN field devices without rewiring the common rail. ## Integration into the panel — what the dimensions and cabling tell you The module measures 35 mm wide, 147 mm high, and 129 mm deep — a compact slice that fits the standard S7-1500 DIN-rail footprint. The 35 mm width is one slot position on the rail, so you can estimate the total rack width from the module count. Cable and connection modules are ordered separately — the module itself has no fixed wiring terminals. You need the appropriate front connector (e.g., 6ES7592-1AM00-0XB0 for 40-pin or 6ES7592-1BM00-0XB0 for 50-pin) and a pre-assembled cable to the field junction box. Factor this into the BOM and the panel wiring schedule. ## Signal timing and wiring distance limits The input transition from 0 to 1 takes a maximum of 100 µs, and from 1 to 0 a maximum of 500 µs. This is fast enough for most discrete sensing (proximity switches, limit switches, pushbuttons) but not for high-speed counting or encoder inputs — the module has no counter function. Maximum cable length is 1 000 m for shielded cable and 600 m for unshielded. In a typical plant-floor installation, shielded cable is recommended for runs beyond 100 m or near variable-frequency drives to avoid noise coupling. ## Lifecycle and sourcing — current production, no cross-reference","metaTitle":"Siemens 6ES7523-1BP50-0AA0 Digital I/O Module, 24 V DC","metaDescription":"Siemens 6ES7523-1BP50-0AA0 digital input/output module for S7-1500.
