What it is and what it does
The 6AG1132-4HB01-2AB0 is a Siemens S7-1200 SIPLUS digital output module with two relay outputs, each rated for 5 A continuous current at 24 V DC supplied from the power module. Intended for switching resistive or inductive loads in control cabinets; the relay type provides galvanic isolation between channels and to the backplane bus. Status indication per output (green LED) and a substitute-value function on CPU STOP are built in; no diagnostic or short-circuit protection is available, so external fusing is required for fault protection.
Key ratings that define fit
The module operates from -25 °C to 70 °C ambient, making it suitable for unheated enclosures or high-temperature cabinet environments. At just 15 mm wide, it slots into tight DIN-rail assemblies; depth is 52 mm and height 81 mm, standard for the S7-1200 form factor. Power loss is 0.6 W typical, negligible for thermal budgeting in dense racks.
