Tips: How to choose the signal isolator
The signal isolator is installed between two system channels, so the input and output functions shall be determined firstly when selecting an isolator. Meanwhile, the input and output mode (voltage mode, current mode, loop power supply mode) of the isolator shall adapt to the interface mode at the front and back channel. In addition, there are many important parameters also relate to product performance, such as accuracy, power dissipation, noise, insulation strength, bus communication. For example, noise relates with the accuracy, power dissipation relates with the reliability. Users should be careful when selection. All in all, main principle of choosing isolator is application, reliability and cost performance.
Analog signal isolator has pluggable terminals, 13mm thickness, input/output isolation, fast response, low-power dissipation, low temperature drift. Signal isolator can connect to various types of signal acquisition device and industrial control device, such as PLC, analog acquisition card, VFD, power meter, electricity record meter, DCS, etc.
