Allen-Bradley P515177154 Double Switch Module

The Allen-Bradley P515177154 Double Switch Module is an aftermarket replacement designed to substitute the original 515177154 in compatible Allen-Bradley control backplanes. Built as a two-switch module, it provides dual switching capability in a single compact unit, enabling independent control of two circuits from one module. As a direct replacement part, it is intended for use wherever the P515177154/515177154 designation appears in AB-based automation assemblies, helping maintain legacy systems without reconfiguring the chassis. The module is designed to match the form factor and mounting footprint common to Allen-Bradley double-switch modules, allowing plug-in installation with minimal wiring changes in standard backplane environments. When selecting this aftermarket part, verify mechanical fit, connector style, and electrical interface meet your system requirements before installation, and consult the equipment manufacturer or a qualified technician to confirm compatibility with your specific backplane and firmware version.
