Overview

The FASTBUS modules FM221, FM222, FS221/N, and FS222/N are designed for distributed substation applications over long distances with minimal signal delay. These modules feature an integrated power supply in the FASTBUS slave modules FS221/N and FS222/N, capable of supplying power to I/O modules within a substation. Flexible connector options allow for easy connections using either patch cables or industrial-grade push-pull plugs with an adapter.
