Finder 50.14.9.024.4310 – 50 Series Relays with forcibly guided contacts

Overview

The Finder 50.14.9.024.4310 is an industrial safety relay with forcibly guided contacts from Finder's 50 Series, designed for use in safety-related control circuits, machinery monitoring and industrial automation equipment. Featuring a 24 V DC coil, four mechanically linked contacts arranged as 3 normally open (NO) and 1 normally closed (NC), and an 8 A rated contact current, this relay provides dependable electromechanical switching for appropriately designed safety control systems.

Unlike conventional general-purpose relays, the Finder 50.14 incorporates forcibly guided contact technology. This mechanically linked contact arrangement helps prevent normally open and normally closed contacts from being closed simultaneously, even under defined contact fault conditions. The technology supports contact-state monitoring and fault detection when incorporated into a suitably designed safety circuit.

The 50.14.9.024.4310 features silver tin oxide (AgSnO2) contacts, compact PCB mounting and a low-consumption DC coil. Its four-contact arrangement makes it suitable for safety monitoring interfaces, emergency-stop control assemblies, guard monitoring circuits and other industrial equipment requiring mechanically linked relay contacts. The relay is a component for safety-related systems rather than a complete standalone safety controller.

Reliable Forcibly Guided Switching for Safety-Related Control Systems

The Finder 50.14.9.024.4310 uses a 24 V DC electromagnetic coil to operate four mechanically linked contacts. When the coil is energised, the three normally open contacts close and the normally closed contact opens. When coil power is removed, the contacts return to their normal positions. The forcibly guided construction provides a defined mechanical relationship between the NO and NC contacts, allowing suitable external monitoring circuits to detect certain contact faults.

This functionality makes the relay useful in safety-related control designs where feedback and diagnostic monitoring are required. However, forcibly guided contacts do not make the relay a complete safety system on their own. Achieving a specified safety performance level or safety integrity level depends on the complete circuit architecture, diagnostics, component reliability, protective measures and validation. The connected load must also remain within the relay's specified electrical ratings.

Typical Applications

• Emergency-stop control circuits: Relay switching and feedback within appropriately designed emergency-stop systems.
• Machine guarding: Contact monitoring in safety-related guard interlock assemblies.
• Industrial safety modules: Integration into electronic safety control equipment.
• Safety monitoring: Mechanically linked contact feedback for fault detection.
• Industrial automation: Safety-related auxiliary switching in machinery control systems.
• OEM safety equipment: PCB integration into purpose-designed safety control products.
• Machinery control panels: Switching and monitoring functions in engineered safety circuits.
• Equipment maintenance: Replacement of compatible Finder 50.14 safety relay components.
