Selection Notes

This 24 V DC variant has Layer 3 routing (RIPv2, OSPFv2, VRRP) built in with no KEY-PLUG needed, so it suits a control-room rack already run on 24 V DC that must route between PROFINET subnets from day one. Its 1 A max draw at 24 V DC is far lighter than the AC-fed 3AR2 and 4AR2 siblings, which matters when panel power budgets are tight. Pick the AC-powered 3AR2 or 4AR2 variant instead when the rack only has 230 V distribution, or the 8GS00-2AR2 sibling when routing can wait behind a KEY-PLUG XR-500 to defer that cost.
