Electromechanical Relay Finder FIN 4C.02.9 24V — 2 changeover (SPDT) contacts, 8 A

Finder FIN 4C.02.9 is an electromechanical relay with a 24 V coil and two changeover (SPDT) contacts rated for 8 A. Intended for general-purpose switching in control panels, automation and building systems, this relay provides electrical isolation between coil and contacts and supports DIN-rail or socket mounting depending on the chosen accessory. The compact design and standardized footprint make it compatible with a wide range of industrial and building installations.

Advantages

The relay offers reliable mechanical switching with silver alloy contacts that ensure consistent performance under resistive and small inductive loads. Its 24 V coil voltage is compatible with common control systems, and the dual SPDT contact arrangement allows versatile circuit configurations for make/break tasks. The product’s construction provides clear separation between the control input and switched circuits, helping to reduce interference and increasing safety in control panels.

Suitable for

• Switching lighting circuits in commercial and residential installations
• Controlling small motors and pumps with limited inrush current
• Interfacing PLCs, timers and control devices with mains or low-voltage loads
• General-purpose signal and control switching in automation systems

Key specifications

• Coil voltage: 24 V DC
• Contact configuration: 2 changeover (SPDT) contacts
• Contact current rating: 8 A (resistive)
• Mounting: DIN-rail or socket (depending on accessory)
• Insulation between coil and contacts: galvanic separation
• Typical applications: control panels, building automation, machine control

How to use

Mount the relay on the appropriate socket or DIN-rail adapter following the socket or rail manufacturer’s instructions and ensure secure mechanical fastening. Connect the coil to a stable 24 V DC control source, observing correct polarity if applicable. Wire the common, normally open and normally closed terminals according to the required switching scheme, and verify that the load connected to the contacts does not exceed the 8 A rating. Perform functional checks after installation to confirm the relay operates as intended within the control circuit.

Usage recommendations

Use the relay within its specified load limits and provide appropriate suppression (RC snubber or varistor) for inductive loads to limit contact wear. Ensure proper ambient conditions and ventilation to avoid overheating. For extended contact life in applications with frequent switching or high inrush currents, consider using the relay to drive an intermediate contactor or a relay with a higher current rating.
