[0002] A signal isolator is a signal isolation device that converts input single-channel or dual-channel current or voltage signals into output isolated single-channel or dual-channel linear current or voltage signals, and improves the electrical isolation performance between input, output, and power supply. Signals may encounter various interferences during transmission. To ensure signal stability, it is particularly important to use a signal isolator. First, the signal received by the PLC is modulated and transformed through semiconductor devices, and then isolated and converted through optical or magnetic induction devices, and then demodulated and transformed back to the original signal before isolation or a different signal. At the same time, the power supply of the isolated signal is isolated to ensure that the converted signal, power supply, and ground are absolutely independent.
