5.2 Operation of the IO-Link I/O modules on a grounded/ungrounded infeed
The figure below shows the overall electrical configuration using the example of an
IO-Link I/O module with port class B on an IO-Link master with port class B.
①
Main switch
②
Short-circuit and overvoltage protection
③
Fuses for cable protection
④
In the configuration of the IO-Link system with ungrounded reference potential, the connection between 1M, 2M
and functional ground is omitted.
