Market Focus: Protecting 24 V Digital Outputs from the Unknown
Designing a robust 24 V digital output channel means planning for the unknown. Unknown loads attached to the channel. Unknown faults on the channel that occur at unknown times and for unknown durations. The solution is a robust array of protection mechanisms that ensure the channel can survive any condition and drive any load. In this session, we will consider the various types of protection required to handle these unknowns.
Technical Focus: A Better Approach to Demagnetization & Overcurrent Protection
Protecting 24 V industrial outputs from demagnetization energy, or voltage kickback as well as overcurrent conditions is critical to safely operate an actuator. In this session, we will
describe a novel approach to active clamping and demonstrate how this technique can be used to discharge inductive loads and provide protection to application circuitry. We will break down the integrated multi-voltage smart clamp featured on the Si834x isolated smart switch. Additionally, we will describe a new approach to protecting against overcurrent conditions deployed on the Si834x that prevents device self-heating during short-circuit events.
