Finder relay finder FIN 34.81 2A for 5VDC/24VDC coils, miniature relay testing accessory

Finder relay finder FIN 34.81 is a compact accessory designed to locate and test miniature relays with coil voltage options of 5 VDC and 24 VDC and a maximum contact current of 2 A. The tool allows technicians to verify coil activation and contact continuity quickly, helping to identify relay types and confirm switching behaviour during maintenance and troubleshooting of electrical panels and control systems.

Advantages

The unit provides a straightforward method to energize relay coils and observe contact response without removing relays from sockets. Its compact size and clear electrical rating make it suitable for bench work and field service. The design reduces diagnostic time by allowing quick verification of coil presence and contact operation while minimising the need for additional wiring or adapters.

Suitable for

• Testing and identifying miniature relays in control panels
• Maintenance and troubleshooting of industrial and building automation systems
• Assembly and quality checks in electrical workshops
• On-site verification of coil activation and contact continuity

Key specifications

• Coil voltage compatibility: 5 VDC and 24 VDC
• Maximum contact current: 2 A
• Form factor: compact, socket-compatible accessory
• Function: coil energizing and contact continuity testing
• Typical applications: relay identification, verification of switching behaviour

How to use

Connect the Finder relay finder to the relay socket or align it with the relay according to the relay type and socket orientation. Apply the appropriate DC coil voltage (5 VDC or 24 VDC) to the accessory terminals and observe the relay contacts for expected operation. Use a multimeter or continuity tester if needed to confirm contact closure or opening. Turn off power before connecting or disconnecting the accessory and follow standard safe work practices when working on live equipment.

Usage recommendations

Use only the specified coil voltages when testing to avoid damaging the relay or the accessory. Verify polarity and secure connections before energising the coil. Store the accessory in a dry, dust-free environment and inspect contacts for corrosion or wear prior to use. For measurements above the accessory’s rated current, use appropriate test equipment or relays rated for higher currents.
