Isolated signal conditioners isolators are widely used in industrial automatic equipment, process controlling systems, automatic actuating & operating systems, etc. It can transmit analog signals like, mV, uV, mA, uA, A, V, pulse, frequency, temperature signal from the industrial equipment or systems, and filter the signal interference between the difference devices to ensure its stability and performance in industrial site.
Current voltage signal Conditioners functions:
1. Isolated signal conditioners isolators build isolation between signal input and output. Using isolated signal conditioner, user can eliminate the interference among the 4-20ma loop signal, signals from difference devices, and filter the electric-magneto interference in signal transmission process.
2. Isolated signal conditioners isolators can effectively avoid the signal conflicts from power supplies. In industrial site, almost all the devices need operating power supply, and power supplies used cause ground interference or conflicts issue, it affects the normal operation and stability of process controlling system. Isolated signal conditioners provide solutions to ensure the normal stable operation of each equipment.
3. Isolated signal conditioners isolators have signal distribution functions. Some instruments or devices control many units of sub-devices, signal conditioners can work as signal splitter to provide connection and controlling solutions.
