Background
In the routine secondary system maintenance and routine test work, when the logic verification of the relay protection device associated with a plurality of devices (intervals) is carried out, the real-time states of a plurality of outlet contacts need to be acquired and judged at the same time, so that the action correctness of the protection device is ensured when a fault occurs.
