Adopt magnetoelectricity isolation module 2320 to constitute isolate demodulation circuit 232, design a transformer isolation circuit 2322, played the effect of signal transmission and electrical isolation based on the operation principle of transformer.The beneficial effect of realizing like this is:
1. adopt transformer isolation circuit 2322 to realize that initiator 10 to the signal transmission of encoder 20 and electrical isolation between the two, has reduced the power consumption of encoder 20, thereby helped improving the load capacity of initiator 10.
