With all the focus on IS loop approval, it is easy to forget to check that the loop will function correctly to see whether the field device has sufficient power (voltage & current) to operate over the full process range.
The intention of this paper is to outline the basic requirements for designing and manufacturing an IS mobile device. What are the risks and what do the standards say? This will explain why IS mobile devices are more expensive than standard rugged devices.
