VOLATILE ORGANIC COMPOUND CONTROLLED RELAY FOR POWER APPLICATIONS

摘要

A power relay (10) controlled by the presence of Volatile Organic Compounds that are often emitted by outgassing from electronic components during overheat and failure conditions. The relay housing (12) contains a standard power relay (22) of single pole single throw (SPST) to multi-pole double throw relays depending on the application. A micro VOC integrated circuit (24) is placed within the housing (12) allowing access to ambient air through ports (14) in the side of the relay (10). Air quality is sample periodically or continuously as is required by the system to adequately monitor for fault events and latch the relay mechanism (22) OPEN breaking the flow of electrical energy to a circuit downstream.
