It carries four command points and four switching elements, with positive opening confirmed on the emergency-stop circuit. The slave is a type A/B slave providing 4 inputs and 3 outputs over the AS-i bus. IP67 protection means the enclosure and the pushbutton seals withstand hose-directed water and dust ingress — suitable for washdown zones on packaging or food-processing lines, not just dry cabinet mounting. The pull-to-unlatch mechanism requires a deliberate pull to reset after a trip, preventing accidental restart. The emergency-stop mushroom pushbutton is red; the integrated illuminated pushbutton is white, with yellow and yellow labels on the other two command points. The A/B slave design supports both standard and extended addressing on the AS-i network, so it drops into a legacy A-slave-only system or a newer mixed A/B installation without changing the master configuration. The DC rated value of 30 V is the AS-i bus voltage — no separate power supply needed for the slave logic. Mounting diameter is 22 mm — fits standard 22.5 mm panel cutouts. The enclosure is rectangular, metal, with a silver metal front ring. Dimensions: 194 mm high, 85 mm wide, 65 mm deep. Floor mounting is the intended orientation.","metaTitle":"Siemens 3SF5814-2DC20 AS-i Emergency Stop, IP67, 4I/3O Slave","metaDescription":"Siemens 3SF5814-2DC20 AS-Interface emergency stop with integrated LED, IP67, A/B slave 4I/3O, pull-to-unlatch.
