Enhancing the SNE Series of contact expansion relays designed to provide additional outputs for machine safety circuits, three new models provide force-guided expansion relays in a wide range of safety applications. The SNE1 features two positively-driven changeover contacts (2 x SPDT), while the SNE 4012 features two normally-open enabling current paths (2 x NO) and the SNE 4024 provides two pairs of independently-actuated enabling current paths (2 x 2 NO).
Housed in a 22.5-mm DIN rail module, the SNE 4012 and 4024 expansion relays are rated for 6 A / 230 Vac switching capacity and the SNE1 is rated for 8A / 250Vac switching capacity. The relays are available in either screw-clamp or spring-clamp configurations to minimize assembly labor and reduce maintenance time, and are approved for machine safety applications in accordance with PL e /category 4 in accordance with EN13849-1 and SIL3 (EN62061) standards.
