What are the forms of signal isolators?

What are the forms of signal isolators? The following signal isolator manufacturer Xiaobian for you to briefly introduce.

1. Input loop power supply isolation type

For this isolation technology, the electrical energy required by the input and output component lines comes from the input end, and the input end provides electrical energy by means of loop power supply. The general loop current is a 4 ~ 20mA standard signal, which is used as an input signal (such as a PLC output card), and the input signal is isolated and provided to the regulator or actuator through the output end. The loop powered isolator is easy to use without additional auxiliary power.

2. Output loop power supply isolation type

For this isolation technology, the power required by the input and output component lines are from the output end, the output end is the use of loop power supply to obtain power (for example, PLC input card), the loop current is generally 4 ~ 20mA standard signal, here as the output signal.

The input can be the signal of various sensors, or it can be the standard signal of 4 ~ 20mA. The important feature of this technology is that the signal current flowing to the output must not only supply power to the isolation unit, but also supply the load of the isolator. (such as input resistance of PLC input card).

3, the output loop power supply isolation, and the input distribution type for this isolation technology, the input and output component line required power from the output end, the output end is the use of loop power supply method to obtain power (such as PLC input card), the loop current is usually 4~20mA standard signal, here as the output signal.
