4.19.4.10.2 Link selector X20HB8884
The link selector was developed for connecting POWERLINK controlled nodes. The device structure follows the
proven X20 philosophy. The 62.5 mm wide module is operated as a stand-alone unit. That makes it possible to
operate all types of POWERLINK devices on a network with cable redundancy.
