ATL-957 short circuit isolators

Overview
ATL-957 short circuit isolators are used for the short circuit fault protection of buses. When a bus circuit is operating normally, the GL-957 short circuit isolator will not operate; when a short circuit fault occurs at a place at the output end of the short circuit isolator in the bus circuit (short-circuit current ＞200mA), the section suffering the short circuit fault will be cut off from the bus, thus ensuring the normal communication of the other sections of the bus. Upon elimination of the short circuit fault, the short circuit isolator can automatically bring the isolated section into the system again. A short circuit isolator will make it convenient to confirm the location suffering a short circuit fault. The short circuit isolator does not need coding nor occupies the address in the bus circuit.
