The Siemens 6AG1223-1PH30-4XB0 is a SIPLUS S7-1200 digital I/O module packing 8 inputs and 8 relay outputs, built for an ambient temperature range of -40 to 70 °C. Power draw sits at 5.5 W typical. The relay outputs switch loads up to 200 W AC (30 W DC) on lamp loads, and the inputs accept 15 V DC at 2.5 mA for signal '1'. Short-circuit protection is not internal—provide it externally per your design.
Rated for -40 to 70 °C operation, this SIPLUS module is suited for environments beyond the standard commercial temperature range.
Integration notes for installation
Front connector is required (not included). The module provides diagnostic alarms and a status indicator for each input, so wiring checks go faster during commissioning. Parameterization is supported, meaning you can set input delays and output substitution values via TIA Portal. Max. cable lengths: shielded 500 m, unshielded 150 m. Input signal transition times are 10 ms max both directions—adequate for most industrial sensors but not for high-speed counting. Protection class IP20. Fall height tested at 0.3 m (five times in package). That's a handling spec, not an in-service rating.
