Input 4-20mA current signal and output isolated current or voltage signal to achieve mutual isolation between input and output. This product has fast response, low power consumption, and good temperature characteristics. It can be used in conjunction with various instruments, DCS, PLC and other equipment, and has a wide range of applications in major projects in industries such as petroleum, petrochemical, manufacturing, power, metallurgy, etc.

What is a passive isolator?

Adopting a "passive" working mode, which means no external power supply is required and no independent power interface terminals are set up. The so-called "passive" working mode refers to the voltage consumed by the circuit being provided by the signal input terminal (circuit) or output terminal (circuit), that is, the circuit is powered by the input terminal (circuit) or output terminal (circuit),Implement signal isolation and conversion. Therefore, passive isolators can be further divided intoInput end circuit power supply isolatorandOutput end circuit power supply isolator.

Input end circuit power supply isolator:

The input and output signals are both DC current signals, without the need for an external power supply. The power energy is obtained from the input signal terminal to achieve signal isolation and conversion. The circuit can achieve one input, one output (one in, one out), and two inputs and two outputs (two in, two out).

• Output end circuit power supply isolator:

  The input signal is a DC current or voltage signal, which does not require an external power supply. The power energy is obtained from the output signal terminal, and the output signal is a 4-20mA two-wire current, which can be output to DCS or PLC equipment,The load powered by the circuit can bePLC、DCSWaiting for cards with voltage output,The circuit can achieve one in one out and two in two out.
