The main function of the DC signal isolator is to carry the isolation and anti-interference suppression treatment for the DC signal generated by the signal source, and then output the Source 1 or Source 2 independent loop DC signals for the control system or other unit combination instruments to realize the mutual isolation between input, output and power supply and to overcome inverter noise and various high and low frequency pulsation interference. It can be used with various instruments and DCS, and PLC, and is widely used in major projects in petroleum, petrochemical, manufacturing, electric power, and metallurgy industries.
