Siemens 6FM1470-3BA21 Circuit Board Side Hinge

Siemens 6FM1470-3BA21 WF470 Color Display Module is a replacement display assembly for the SIMATIC S5 WF470B memory/display units, delivering the color user interface needed to view module status and diagnostics in legacy automation setups. Marketed as the WF470B color display replacement, it provides three memory-module slots and two serial interfaces, designed for repair or refurbishment of existing WF470B assemblies without replacing the entire display unit. The part number 6FM1470-3BA21 uniquely identifies this variant, intended for use in Siemens S5 systems where the WF470B family provides the operator-facing display for memory-related modules. Typical applications include retrofitting or restoring color display capability in older Siemens control panels and production lines that rely on SIMATIC S5 technology, helping maintain visibility of memory-module information and system diagnostics in ongoing operations.
