What this AS-Interface slave brings to the panel
The Siemens 3SF5813-2DB00 is an AS-Interface A/B slave packing 4 inputs and 3 outputs in a metal IP67 enclosure — rated for 30 VDC on the DC side, with three pushbutton command points and three switching elements. The IP67 rating means the housing and optics survive washdown environments, so it fits right on a conveyor line or packaging machine where dust and spray are the norm. Mounting diameter is 22 mm, and the enclosure mounts vertically on a floor or panel surface — not a DIN-rail clip, so plan for screw-down or bracket attachment.
What the ratings mean for fit
The 4 inputs and 3 outputs on an A/B slave give you flexibility on the AS-i network — you can mix standard and extended addressing without swapping hardware. The 30 VDC rated supply is typical for AS-Interface bus power, so it drops into an existing AS-i segment without a separate power supply. Operating temperature from -25 to +70 °C and storage from -40 to +80 °C cover most factory floor conditions, including cold storage areas. The metal enclosure and IP67 seal mean it handles washdown cycles and vibration better than a plastic housing would.
