Switching Inductive Loads With Relays and Solid State Devices in Process Control

Switching devices must be properly protected for longevity
We connect a lot of black boxes together in our control systems, not really knowing what goes on inside. There is a basic understanding of function, but maybe not enough knowledge to thoroughly assess all aspects of integrating a device into a train of control system components. We range from novice to seasoned expert, so Acromag, manufacturer and global supplier of I/O devices for process control, has provided a useful application note regarding the protection of devices employed to switch inductive loads.

The application paper provides a good explanation of what an inductive load is, and how it can impact the performance and longevity of a switching device. The document further explains how to offset the potentially damaging impact of an inductive load on a connected switching device, with specific examples and recommendations on how to put the protective measures in place. It is useful information.

The paper is provided below. Share your I/O and other process measurement and control challenges with application specialists, combining your own process knowledge with their product application expertise to develop effective solutions.
