The '0' side is qualified with 0.1 V at a 10 kOhm load, so this module is meant to be driven by a sourcing 24 V signal, not by a dry contact wired directly to the terminal. Worst-case transition times are 50 µs '0' to '1' and 200 µs '1' to '0' — fine for pushbuttons, limit switches, and standard 24 V proximity devices, but worth checking against any high-speed pulse train. Cable runs are derated to 500 m shielded or 150 m unshielded — that ceiling, not the bench length, is what a long-plant layout has to respect. ## Output side: per-channel limits and the figure that actually governs the panel Diagnostic and status bits are present per input and per output, and the module is parameterizable — channel-level diagnostics and a diagnostic alarm ride on the backplane, so a wireman can wire it in and let the programmer decide what gets monitored. ## Extended-temperature behaviour and the cold-restart gotcha Ambient is rated -40 °C to 70 °C, which is the headline number on the SIPLUS line. The 0 °C minimum at cold restart is the quiet detail that matters: a cabinet that is powered up from cold still has to be above freezing before the module will bring its outputs live, even though it will sit at -40 °C once running. Mechanical handling is qualified for a 0.3 m fall height, five times in product packaging — the SIPLUS shipping and drop envelope, not a panel-side handling spec.","metaTitle":"Siemens 6AG1223-1BL32-4XB0 SM 1223, 16 DI / 16 DO, -40…70 °C","metaDescription":"Siemens SIPLUS 6AG1223-1BL32-4XB0 digital I/O module, 16 inputs / 16 outputs, 24 V DC, -40 °C to 70 °C.
