EP6228-3132 | 8-channel IO-Link master, 4 x Class A, 4 x Class B, 4 x digital input

The EP6228-3132 IO-Link module enables connection of up to eight IO-Link devices, e.g. IO-Link box modules, actuators, sensors or combinations thereof. The EP6228-3132 additionally offers further digital inputs on the four Class A master ports. A point-to-point connection is used between the module and the device. The terminal is parameterized via the EtherCAT master. IO-Link is designed as an intelligent link between the fieldbus level and the sensor, wherein parameterization information can be exchanged bidirectionally via the IO-Link connection. The parameterization of the IO-Link devices can be done from TwinCAT via ADS or very conveniently via the integrated IO-Link configuration tool.

In the standard setting, the EP6228-3132 functions as a 8-channel input terminal, 24 V DC, which communicates with connected IO-Link devices, parameterizes them and, if necessary, changes their operating mode.
