Description

Welcome to purchase discount source isolated safety barrier intrinsic safety barriers from our company, which is one of the best China isolated safety barrier intrinsic safety barriers manufacturers and suppliers.

Isolated safety barrier uses electrical isolation of the circuit structure between the input, output and power. At the same time, it meets the energy limit requirements of intrinsic Safety Barriers type.

 

Some special field not only need a two-wire transmission, it also needs to provide distribution of power supply & signal isolation function, and have the explosion proof performance. The signal barrier reliably prevent the mixed contact between high-voltage power supply & signal and use current and voltage double loop limit, limit the energy into dangerous places in rated value safety barrier with special function of electrical appliances.

 

In addition to the function of limit voltage and current, the isolation type signal safety barrier is also with the function of the current isolation. The isolation type signal safety barrier is usually composed of three parts: the loop current limiting unit, the current isolation unit and the signal processing unit.

 

As with functions of limit pressure, current limiting, isolation, isolated safety barrier can not only prevent hazardous energy from the terminal of the intrinsically safe into the dangerous site to improve the system safety and explosion-proof performance, but also to increase the anti-interference ability of the system, which greatly improving the reliability of the system operation.

 

Isolation type safety barrier are usually with two types: detection end type safety barrier and the operation end type safety barrier. The detection end type safety barrier is in combined use with two wire transmitter; while the operating end barrier is in combined use with the electric converter or the electric valve. There are also Signal input and other types of isolated safety barrier.

 

Advantages of isolated safety barrier

1) The isolated safety barrier can effectively isolate the field circuit signal and the safe zone circuit signal. In this case, it simplifies the construction application of explosion-proof system.

2) The isolated safety barrier has greatly enhanced the ability of anti-disturbance of detection and control circuit, which can improve the reliability of the system.

3) The isolated safety barrier allows the on-site instrument grounding and allows the on-site instruments to be non-isolated type.

4) The isolated safety barrier has many circuits with protection function. Therefore, the possibility of accidental damage is quite small.

5) The isolated safety barrier is with strong signal processing ability, such as switch input state control, mV, Pt100 into 4 ~ 20mA, etc.

6) When the user is using DCS and ESD at the same time, the use of one input two output isolated safety barrier can effectively separate the two systems, which avoids the mutual impact between the systems.
