Finder 7S.34.9.110.4310 – 7S Series Relay modules with forcibly guided contacts

Why Choose the Finder 7S.34.9.110.4310 Safety Relay?

The Finder 7S.34.9.110.4310 is a 110 V DC modular safety relay with four 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 multiple switching paths and a feedback contact for appropriately engineered machinery safety circuits.

The relay incorporates Class A forcibly guided contact technology, which mechanically links the normally open and normally closed contacts to support the detection of certain contact failures. Its 6 A rated contact current, 250 V AC nominal switching voltage and silver tin oxide contact material make it suitable for compatible industrial control and auxiliary switching loads.

Featuring screw terminal connections, an illuminated coil status indicator and a compact 22.5 mm-wide housing, the Finder 7S.34.9.110.4310 is designed for straightforward installation on a 35 mm DIN rail. Its combination of forcibly guided contacts, practical wiring connections and reliable switching performance makes it suitable for machinery control cabinets, industrial automation systems and safety-related relay interfaces.

Forcibly Guided Contact Technology for Machinery Safety and Industrial Automation

Safety-related industrial control systems frequently require reliable switching and feedback to determine whether electrical contacts have returned to their intended state. The Finder 7S.34.9.110.4310 uses mechanically linked contacts in a 3 NO + 1 NC arrangement, allowing the normally closed contact to support monitoring of the normally open switching contacts within a correctly designed circuit. This arrangement helps engineers implement monitored switching functions and detect certain contact failures.

The relay's 110 V DC coil, 6 A contact rating, screw terminals and compact DIN rail-mounted construction make it suitable for industrial control panels and safety-related relay interfaces. The Finder 7S.34.9.110.4310 is a relay component rather than a complete standalone safety controller; the achieved safety category, performance level or safety integrity level depends on the complete system architecture, diagnostic coverage and validation.

Typical Applications

• Industrial machinery safety-related control circuits.
• Emergency stop relay interfaces within validated safety systems.
• Machine guarding and safety interlock monitoring.
• Multiple-contact switching and feedback circuits.
• Industrial automation control panels.
• Manufacturing and production equipment.
• Process control and auxiliary switching systems.
• Electrical control cabinets using compatible 110 V DC supplies.
