When selecting equipment,firstly select products with high anti-interference ability,including electromagnetic compatibility(EMC),especially anti-external interference ability,such as PLC system with floating technology and good isolation performance;Understand the anti-interference indicators given by the manufacturer,such as the common analog system ratio,the poor analog system ratio,the withstand voltage capability,and the allowable working in the environment with multiple fire electric field strengths and high frequency magnetic field strengths.
在选择设备时,首先要选择有较高抗干扰能力的产品,其包括了电磁兼容性(EMC),尤其是抗外部干扰能力,如采用浮地技术、隔离性能好的PLC系统;其次还应了解生产厂给出的抗干扰指标,如共模拟制比、差模拟制比、耐压能力、允许在多火电场强度和多高频率的磁场强度环境中工作。
