Bachmann FS221/N

The FASTBUS modules FM221, FM222, FS221/N and FS222/N are

designed to enable distribution of substations over long distances

with a very low signal delay. The power supply integrated in the

FASTBUS slave modules FS221/N and FS222/N can supply the I/O

modules of a substation. The flexible connector concept allows

easy connection via a patch cable or an industrial grade push-pull

plug connection via an adapter.
