Why Choose the Finder 7S.12.9.024.5110 Safety Relay Module?
The Finder 7S.12.9.024.5110 is a modular safety relay with forcibly guided contacts, designed for monitoring and switching functions in industrial machinery and functional safety systems. Part of the specialised Finder 7S Series, it features a 24 V DC coil and two mechanically linked contacts arranged as one normally open and one normally closed contact.
The forcibly guided Class A contact mechanism ensures that the normally open and normally closed contacts cannot be closed simultaneously. This allows an external safety controller or monitoring circuit to detect contact faults, making the module suitable for safety-related applications evaluated up to SIL 2 and Performance Level d when correctly incorporated into a compliant system.
With a slim 22.5 mm modular enclosure, 35 mm DIN rail mounting and push-in terminals, the 7S.12.9.024.5110 is designed for efficient installation in industrial control panels. An integrated LED provides clear coil status indication, while gold-plated silver nickel contacts support dependable switching at both standard and relatively low load levels.
Key Advantages
- Forcibly guided Class A contacts for safety monitoring applications.
- One normally open and one normally closed contact with mechanical linkage.
- Evaluated for functional safety applications up to SIL 2 and PL d.
- 24 V DC coil suitable for safety PLC and industrial control circuits.
- Slim 22.5 mm DIN rail enclosure conserves control-panel space.
- Push-in terminals and LED coil indication simplify installation and diagnostics.
Key Features
- Finder 7S Series modular safety relay.
- 1 NO + 1 NC forcibly guided contact configuration.
- 6 A nominal contact current.
- 24 V DC rated coil voltage.
- Class A forcibly guided contacts compliant with EN 61810-3.
- Silver nickel contacts with gold plating.
- Integrated LED coil status indication.
- Push-in terminals and 35 mm DIN rail mounting.
Dependable Monitoring for Functional Safety Systems
Forcibly guided relays mechanically link their normally open and normally closed contacts so that a welded contact can be detected through the opposite monitoring contact. This provides predictable feedback to a safety PLC or control circuit and helps identify dangerous contact failures.
The Finder 7S.12.9.024.5110 is intended for incorporation into appropriately designed safety-related control systems. Its safety performance depends on the complete system architecture, diagnostics, wiring and validation rather than the relay module alone.
Typical Applications
- Machine safety and emergency-stop control systems.
- Safety PLC output expansion and feedback monitoring.
- Guard door and protective device circuits.
- Industrial lifts, escalators and automated warehouses.
- Process machinery and plant engineering.
- Crane, material handling and production equipment.
