Selection Notes

This is the single-supply, AC/DC-rated version in the XRM334 family; the 4AR3 sibling adds a second independent power input for supply redundancy. Like other XRM334 variants it carries an optional Layer 3 upgrade license, unavailable on the XR322-12 family, for sites that may need routing later. It is also the only SKU in this batch with a published IEC 62443-4-2:2019 cybersecurity certification and railway-application approvals (EN 50121-4, EN 50125-3), relevant where the network sits in a regulated or trackside environment.
