Finder 40.52.9.024.5001 Relay Module 8 A Changeover Contacts (2 CO)

Finder 40.52.9.024.5001 Relay Module is a compact switching component featuring two changeover (CO) contacts rated at 8 A. Intended for control and automation installations, this relay module provides electrical isolation between coil and contacts and enables reliable on/off switching of low- and medium-load circuits. The unit is suitable for panel or DIN-rail mounting and integrates into HVAC systems, building automation, and appliance control panels where space-saving, repeatable switching is required.

Advantages

The module combines two independent changeover contacts in a single compact housing, reducing footprint in distribution panels. Its 8 A contact rating supports typical control loads such as small motors, resistive heaters, lighting circuits, and signal lines. The design offers galvanic isolation between control input and switched outputs, improving safety and minimizing interference. Robust switching performance and compatibility with standard mounting options simplify installation and maintenance.

Suitable for

• HVAC control systems
• Home appliance control panels
• Building automation and lighting control
• Small motor and pump switching
• Signal switching and control circuits

Key specifications

• Contact configuration: 2 changeover (2 CO) contacts
• Contact rating: 8 A (resistive/typical switching loads)
• Coil and contact electrical isolation for safe control
• Mounting: panel or DIN-rail compatible compact housing
• Application class: switching and control in automation, HVAC, and appliances

How to use

Install the relay module on a compatible DIN rail or mount it inside a panel according to local wiring regulations. Connect the control coil to the appropriate control voltage source and wire the changeover contacts into the load circuit, ensuring contact ratings match the connected devices. Verify correct polarity and secure all terminations. Test the switching operation under no-load conditions first, then under normal load to confirm reliable operation before full commissioning.

Usage recommendations

Use appropriate surge suppression and protection devices when switching inductive loads such as motors or solenoids to extend contact life. Ensure the connected load does not exceed the 8 A rating and maintain proper ventilation around the module to avoid overheating in confined enclosures.
