BM Series Analog Signal Isolator

In practical applications, the signal interference problem in the control system is sometimes very serious. Sometimes even if the signal cable uses shielded wires, the interference cannot be completely eliminated, such as ground loop current interference caused by different grounding points. The wiring method using BM series analog signal isolator cuts off the propagation path of conducted interference and reduces the signal distortion caused by the ground loop directly connected to the equipment. At the same time, it can effectively improve the safety, stability and relative independence of each signal power supply of the analog control module in the PLC/DCS control system. This can reduce the probability of template breakdown or burnout caused by lightning over-voltage and other reasons, improve the measurement accuracy of the control module and the ability of the 4-20MA analog signal to resist power frequency electromagnetic interference, and ensure the safe and stable operation of the control system.
