The 8 DO (digital outputs) are parameterizable via the MSS ES software, meaning you can configure their behavior — like assigning them to specific safety functions or setting delay times — without rewiring. This is a key differentiator from fixed-output safety modules: one part covers multiple machine guarding scenarios. IP20 protection means it's intended for use inside a control cabinet, not in wet or dusty areas. The screw-type terminals accept standard ferruled wires, and the finger-safe touch protection keeps panel builders safe during commissioning. The 24 V DC control supply voltage is standard for safety circuits, and the 0.5 A per output is enough to drive small contactors, indicator lamps, or PLC input modules. For larger loads, you'd buffer through an interposing relay. This module sits inside a safety control panel, typically as part of a SIRIUS 3RK3 modular safety system. It handles the non-safety-related outputs (8 of them) — things like status lights, auxiliary contactors, or reset circuits — while the safety-rated logic handles the actual machine guarding functions.","metaTitle":"Siemens 3RK3311-1AA10 SIRIUS Extension Module, 8 DO, 24 V DC","metaDescription":"Siemens 3RK3311-1AA10 SIRIUS extension module for modular safety system 3RK3. 8 digital outputs, 24 V DC/0.5 A, parameterizable via MSS ES.
