esserbus Loop Card With Galvanic Isolation for Esser FX808332 FlexES Control

A loop card with galvanic isolation for esserbus and esserbus-PLus circuits; it prevents disturbances occurring on one line from being transmitted to other circuits and to the control panel itself. From the fifth circuit onwards, this type of card must be installed in the control panel; isolated and non-isolated cards can operate together on the same panel. It draws approximately 30 mA standby current and weighs 140 g. On long lines distributed across different buildings, it limits the effect of faults to a single circuit.
