For the I/O INTERFACES manufacturers Italtronic has designed a complete range of products which covers the Customers’ needs. ITALTRONIC has added the Railbox enclosure to the standard product SUPPORT, already known as pcb holder for DIN rail and available in 72 or 107 mm width. RAILBOX, with a smart and modular design, allows to decrease the necessary space for the relay pcbs mounting. The always increasing need of smaller relays took ITALTRONIC to develop the Relay Socket enclosure. Besides, GUIDEBOX Compact enclosure is available for applications where extremely small and thick enclosures are needed – i.e. optocoupler.
