Abstract
Provided herein are approaches for determining a status of a fuse or relay. In some embodiments, a system may include a first fuse or relay connected between a first input and a first output, and an optocoupler electrically connected with the first fuse or relay, wherein the optocoupler is operable to monitor a differential voltage of the first input or the first output. The system may further include an input/output (IO) expander receiving a status signal representing a state of the first fuse or relay, wherein only a single input port of the IO expander receives the status signal representing the state of the first fuse or relay.
