Selection Notes

The 6AV2128-3XB27-0BX0 pairs an expandable round-pipe support arm with an Extension Unit, so pick it when the installation needs to add distance or a second mounting point later without swapping the arm hardware. Its 1A rated current draw and 24W typical input power fit standard 24V DC control cabinet supplies without oversizing the PSU. Where the mount never needs to expand, a fixed support-arm version is the simpler and lighter choice for the same 21.5-inch display.
