Relay accessories are devices to support the design and maintenance of relays in electrical circuits. These include auxiliary contact blocks, busbars, clips, interfaces, labels, mounting adapters, relay covers, and sockets. Auxiliary contact blocks are available in several configurations, including DIN rail, and provide breakout for the signals to the relay and are used for testing. Busbars are available for high current shorts across relay connections and are usually in break off strips of connection pairs. Mounting adapters provide adaptation between standard socket types, while relay covers help provide extra safety and protection from the environment. Sockets are used for relay mounting in configurations, including PCB types and DIN rail. Clips are used to secure the relay in the connector as well as labels for safety warning and standard signal types.
