Extension Adapters FX1N-4EX-BD, FX1N-2EYT-BD
The extension adapters for the FX1N series are available with 4 inputs or 2 outputs.
They are installed directly in the controller of the FX1S or FX1N series and therefore do not
require any additional installation space.
These adapters are especially advantageous when only few additional I/Os are required
and there is not enough room for an adjacent module to be installed.
