RTD.) Electrical Noise and Interference Process Technology electronic controls are engineered, tested and manufactured to conform to Europe’s CE levels of electrical noise and interference found in typical industrial installations. It is always possible for electrical noise and interference to exceed the level of designed-in protection. This can happen, for example, if arc or spot-welding equipment is close to the control or if they share a common power line.
