Bud Industries’ DIN-rail-mount terminal-block enclosure gives design flexibility, minimizes component installation time, and costs up to 25 to 40% less than comparable enclosures. It is suited for housing printed circuit boards and terminal blocks used in DIN-rail mounted industrial controls, relays, and test equipment. The enclosure has space for three circuit boards, allowing for more complex functionality in the terminal block without increasing its size. Modularity enables variation of functions and features by substituting secondary circuit boards, while snap-fit design allows tool-less assembly of parts. An optional transparent cover permits users to see indicating lights. The enclosure has room for 12 to 54 terminals, depending on the model.
