Selection Notes

The included Layer 3 upgrade license and higher 2048 max VLAN count separate the XRM334 from the plain XR326-8 in the same 19-inch chassis: it routes between VLANs out of the box and supports finer network segmentation. IEEE 1588 v2 time synchronization down to 50 ns typical accuracy adds a capability the XR326-8 spec sheet does not list. Choose this 24 V DC input over the 230V AC or 2x230V AC XRM334 variants when a DC control bus already reaches the cabinet.
