Product News 7S

Product catalog summary

Overview: The 7S Series relays are designed for safety applications compliant with the Machinery Directive. They serve as interfaces between systems operating at different voltages, providing electrical isolation and safety contact expansion. These relays are applicable in various industries, including machine tools, elevators, security modules, safety barriers, and railways.

Specifications: The relays feature forcibly guided contacts and are approved according to EN 61810-3 Class A. They are suitable for applications up to SIL 2 as per IEC 61508 and ensure functional reliability in machinery and plant engineering according to EN 13849-1. The materials used comply with fire and smoke characteristics for railway applications (EN 45545).

Features: The relays are available with 2, 3, 4, or 6 forcibly guided contacts. They come with either screw or screwless terminals and are designed for 35 mm rail mounting (EN 60715). The relays include LED indicators for coil status and are available in widths of 17.5 mm or 22.5 mm.

Product Variants:

2 Pole (1 NO + 1 NC): Rated current of 6 A, nominal voltage of 110...125 - 230...240 V AC or 12 - 24 V DC, cadmium-free contacts, and contact material AgNi+Au.
3 Pole (2 NO + 1 NC): Rated current of 10 A, nominal voltage of 12 - 24 - 48 - 110 V DC, cadmium-free contacts, and contact material AgNi+Au.
4 Pole (2 NO + 2 NC or 3 NO + 1 NC): Rated current of 6 A, nominal voltage of 110...125 - 230...240 V AC or 12 - 24 - 110 V DC, cadmium-free contacts, and contact materials AgSnO₂.
6 Pole (4 NO + 2 NC): Rated current of 6 A, nominal voltage of 110...125 - 230...240 V AC or 12 - 24 - 110 V DC, cadmium-free contacts, and contact materials AgSnO₂ + Au.

Applications: The relays are suitable for safety applications in various sectors, including machinery, elevators, security, and railways. They are designed to ensure safety and reliability in these environments.
