Termination Boards
Termination boards form the wiring level for field and control signals. The isolated
barriers are mounted on termination boards. The isolated barriers are connected
with the field and control side via the termination boards. Once the isolated barrier
is mounted, the signal circuit between the field and control side is closed.
