The SIPLUS S7-300 SM 326 10F-DO (6AG1326-2BF10-2AB0) is a fail-safe digital output module from Siemens, \ndesigned for SIMATIC S7-300 systems. It features 10 digital outputs (F-DO) operating at DC 24 V/2 A PP, supports \ndiagnostic alarms and LVV (Last Valid Value) functionality, and complies with Category 4 (EN 954-1) and SIL 3 (IEC 61508) \nsafety standards. Equipped with conformal coating and capable of operating in a temperature range of -25 to +60 °C (up to 70 °C \nwith forced convection), it is ideal for harsh industrial environments. It connects via a 1x 40-pin connector. DIN rail mounting and a compact \ndesign ensure easy installation in control cabinets while saving space. It is used in industrial automation systems, particularly for controlling processes with high safety requirements.
