Solution Overview

Problem

Existing relay systems require separate designs and procurement for conventional and latching relays, which can be cumbersome and inefficient, especially when design changes occur, as they cannot be easily converted between modes.

Innovation Solution

AI summary

A method of controlling the behavior of a latching relay includes receiving a configuration signal of either a first behavior signal or a second behavior signal, receiving a power status signal of either a powered or unpowerered signal, receiving either a low-to-high or a high-to-low signal command signal, generating latching pulse in response to receiving a powered signal input as the power status signal and a low-to-high signal as the command signal, generating an unlatching pulse in response to receiving a powered signal input as the power status signal and a high-to-low signal as the command signal input, and generating an unlatching pulse in response to receiving the second behavior signal as the configuration signal and the unpowered signal as the power status signal.
