Abstract
The paper describes design details of low-cost, versatile, linear as well as digital optocoupler circuits used to reduce noise and ground loop errors in measurements. A detailed description of a linear optocoupler circuit for providing galvanic isolation between photodiode signal conditioner ground and the data logger ground is given. We also report use of two single-channel high-speed digital optocouplers to communicate through RS232 protocol isolating the ground of the devices in the detection region of the Cs fountain frequency standard being developed at NPL India. These isolators are versatile, affordable, and give very good results.
