Why Choose the Finder 7S.14.9.110.4310 Safety Relay?
The Finder 7S.14.9.110.4310 is a 110 V DC modular safety relay with forcibly guided contacts, designed for safety-related switching, contact monitoring and industrial automation applications. Part of the Finder 7S Series, this relay features 3 normally open (NO) and 1 normally closed (NC) contacts, providing three switching paths and a feedback contact for appropriately engineered safety control circuits.
The relay uses mechanically linked, forcibly guided contact technology to support the detection of certain contact failures, including welded contacts, through correctly designed monitoring circuits. Its 6 A rated contact current, silver tin oxide contact material and 250 V AC nominal switching voltage make it suitable for a range of industrial control and auxiliary switching applications.
With a 110 V DC coil, spring-loaded screwless terminals, an integrated illuminated status indicator and DIN rail mounting, the Finder 7S.14.9.110.4310 offers practical installation and maintenance benefits. Its compact construction makes it suitable for machinery control cabinets, industrial automation panels and safety-related relay interfaces where reliable switching and contact feedback are required.

Forcibly Guided Contact Technology for Industrial Safety and Automation
Industrial safety-related control systems often require feedback to verify whether switching contacts have returned to their intended state. The Finder 7S.14.9.110.4310 uses forcibly guided contacts to support this function. Its 3 NO + 1 NC arrangement provides three normally open contact paths and a normally closed contact that can be incorporated into an appropriately designed feedback or monitoring circuit.
The relay is particularly useful in machinery control panels, industrial automation interfaces and safety-related switching systems operating with 110 V DC control supplies. Its spring-loaded terminals and illuminated indicator support installation and troubleshooting. The relay itself is not a complete safety controller; the safety performance of an installation depends on the overall circuit design, diagnostic coverage, protective measures and validation.
Typical Applications
- Industrial machinery safety-related control circuits.
- Emergency stop relay interfaces within validated safety systems.
- Machine guarding and interlock control arrangements.
- Industrial automation control panels.
- Contact feedback and fault monitoring circuits.
- Manufacturing and production equipment.
- Process control and auxiliary switching systems.
- Electrical control cabinets using 110 V DC control supplies.
