FEA-01 F-series Extension Adapter
Overview
The FEA-01 F-series Extension Adapter is an extension unit for the
mounting of FIO I/O extension modules and FEN encoder modules
outside the drive unit. The FEA-01 is connected to the drive via a
DDCS-protocol fiber-optic link. One I/O extension module can be
mounted on one FEA-01 adapter. Several FEA-01 adapters can be
connected in a ring topology using fibre optic cable.
Optical component types
The FEA-01 has a 10 MBd fiber-optic link. The drive must also
have a 10 MBd DDCS fiber-optic connection. The following optical
cable types can be used:
Note:
The optical components (transmitter and receiver) on a fibre
optic link must be of the same type.
•
Plastic optical fibre (POF) cables (max. length 30 m) and
•
Hard Clad Silica (HCS
®
) cables (max. length 200 m).
HCS cables allow longer connection distances because of their
lower attenuation. HCS
