1.Ankerui three wire transmitter equipment isolation barrierOverview

The BM200 series isolated safety barrier provides power to transmitters in hazardous areas. The current signal generated by the transmitter is isolated and converted into a corresponding linear voltage or current signal for output to the safe area. This product requires independent power supply, with input/output/power isolation. Can be used in current source, two-wire system, and three wire system transformersDelivery equipment.

4. Characteristics

Adopting a circuit structure that electrically isolates the input, output, and power supply from each other, while complying with the requirements of intrinsic safety energy limitation. Compared with Zener safety, although the price is slightly higher, its outstanding advantages in other aspects have brought greater benefits to user applications:

Due to the use of a three party isolation method, there is no need for a system grounding line, which greatly facilitates design and on-site construction. The requirements for instruments in hazardous areas have been significantly reduced, and there is no need to use isolated instruments on site.

2. Due to the fact that the signal lines do not require a common ground, the stability of the detection and control circuit signals is improvedAnti-interference abilityGreatly enhanced, thereby improving the reliability of the entire system.

3. Isolated safety barriers have stronger input signal processing capabilities and can accept and process signals such as thermocouples, thermistors, frequencies, etc., which cannot be achieved by Zener safety barriers.

4. The isolated safety barrier can output two signals that are mutually isolated to provide to two devices using the same signal source, ensuring that the signals of the two devices do not interfere with each other and improving the electrical safety between the connected devicesinsulation performance.
