Electrical isolation
BK5200, BK5210
The BK5200 and BK5210 Bus Couplers have electrical isolation between the DeviceNet bus cable and the communication electronics of the Bus Coupler.
LC5200
The LC5200 does not provide electrical isolation from the fieldbus and peripheral level. If the peripheral level nevertheless needs to have an electrically isolated implementation, this can easily be achieved through the use of isolating terminals (KL9xxx).
