Function
Isolated barriers are used to protect intrinsically safe circuits in explosive areas. In
addition to the required current and voltage limitation, the isolated barriers have a
galvanic isolation between the field circuit and the controller.
The H-System isolated barriers are mounted on termination boards. Pre-wiring is
possible on termination boards. To close the signal circuit, the isolated barriers
are simply plugged in. The isolated barriers can be replaced during live operation
when the wiring is connected.

Universal and control system-specific termination boards are available in the
H-System. Termination boards can be adapted to specific input/output
requirements. These requirements can be implemented via
• Various connecting plugs to the controller
• Various terminals to the field device
• A large selection of isolated barriers
