Contact expansion relays provide additional outputs

WIELAND SNE Series contact expansion relays switch enabling current paths in safety applications up to PL e / Category 4 / SIL. Devices provide 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 22.5mm DIN rail module, the SNE Series expansion relays are rated for 6A / 230Vac switching capacity and the SNE is rated for 8A / 230Vac switching capacity.
