D9057BAddressable Isolator Base
Key features
- The isolator base does not need to be coded and does not occupy an address in the loop
- When the short-circuit fault is removed, the isolation chassis will be de-isolated and the isolated part of the device will be re-connected to the bus

The D9057B isolator base 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.
