Introduction
The isolator provides isolated working power to 2-wire and 3-wire transmitters, isolating and converting the current signal generated by the transmitter into signals required by other instruments. It achieves three-terminal isolation between input, output, and power, thereby improving the industrial process control system's anti-interference capability, ensuring system stability, and reliability. The isolator can be used in conjunction with various instruments, DCS, PLC, and other equipment, and has wide applications in major projects in industries such as petroleum, petrochemical, manufacturing, power, and metallurgy.
Note: This product is not allowed for use in explosion-proof environments.
