Isolation Base D9057B

The isolation base D9057B is used to protect the bus in the event of a short-circuit fault.
When a short-circuit fault occurs somewhere on the bus, the isolator base adjacent to the short-circuit will act quickly and cut off the short-circuited part, thus ensuring that other devices on the bus can work normally. When the short-circuit fault is removed, the isolation chassis will be de-isolated and the isolated part of the device will be re-con-nected to the bus. The isolation base D9057B does not need to be coded and does not occupy an address in the loop.
