Signal isolators can generally be divided into digital power amplifier signal isolators and passive signal isolators. It is generally believed that the passive signal isolator can work without external power supply; The digital amplifier signal isolator requires an external power supply, such as 24VDC or 380VAC. Signal isolator brand.

Passive signal isolator is to use the signal flow in the input control loop to power the instrument panel (refers to taking a part of the kinetic energy of the input signal inside the instrument panel to drive the isolator work), without external power supply source, obtain a small amount of kinetic energy from the input signal, complete signal protection, and can cooperate with a variety of industrial sensors and spot dashboards. Take back the main parameter signal, protect the transmission, to meet customer needs to monitor the local remote control data information requirements.

Signal isolator Brand - Advantages of Passive isolators:

1. Easy to use, highlighting economic development, saving the power supply for the isolator and its power cord;

2. Modular, small size, power consumption, high reliability. Signal isolator brand.
