Finder miniature relay 55.34.9.024.5090, 4W changeover, 7 A, 24 V DC

Finder miniature relay 55.34.9.024.5090 is a compact electromechanical changeover relay designed for low-voltage control and automation applications. The relay features a 4W changeover contact configuration and is specified for switching currents up to 7 A at 24 V DC. Its small footprint and robust construction make it suitable for use in HVAC systems, lighting control, security panels and various industrial control circuits where reliable signal and power switching are required.

Advantages

The relay provides stable mechanical switching with clear contact separation and a defined operating point for DC control at 24 V. Its compact size allows installation in confined spaces and on control panels with limited room. Designed for frequent switching, the device combines reliable contact performance with straightforward integration into standard relay sockets or PCB layouts. The relay’s rated switching current and voltage make it suitable for many signal-level and low-power actuator applications.

Suitable for

• Signal switching in HVAC control systems
• Lighting control circuits and lamp switching
• Security and alarm panel outputs
• Industrial automation control relays and PLC interfaces
• Compact assemblies and tight-space installations

Key specifications

• Contact configuration: 4W changeover (multiple changeover contacts)
• Nominal switching current: 7 A
• Coil nominal voltage: 24 V DC
• Mounting: suitable for relay sockets or PCB mounting depending on socket type
• Application: low-voltage control and signal switching
• Form factor: miniature relay for space-constrained installations

How to use

Mount the relay in a compatible socket or secure it according to the installation requirements of the control panel. Connect the 24 V DC supply to the coil terminals and wire the common, normally open and normally closed contacts according to the circuit diagram. Verify polarity and wiring before energising the coil. Test switching operation at low load first to confirm correct contact action and then place the relay into normal service. Follow all applicable electrical safety standards during installation and commissioning.

Usage recommendations

Use the relay within its specified electrical ratings and in environments that match the relay’s intended application. Protect contacts from excessive inductive loads by using suitable suppression (for example diodes for DC coils or RC/snubber networks for switched loads) and ensure proper thermal management when multiple relays are installed in close proximity.
