Finder 026.9.024 – 26 Series Step Relays – Accessory

Why Choose the Finder 026.9.024 24V DC Adapter for Series 26 Impulse Relays?

The Finder 026.9.024 is a compact 24 V DC control adapter designed for use with compatible Finder 26 Series impulse relays. This purpose-built accessory enables compatible impulse relays with 24 V AC coils to be operated from a 24 V DC control circuit, providing a practical solution for electrical installations where direct-current control supplies are available.

Part of the Finder 26 Series relay accessories range, the 026.9.024 is particularly useful in lighting control systems, building automation installations and electrical control circuits that use low-voltage DC pushbutton commands. By adapting the control supply for a compatible AC-coil impulse relay, it allows installers to retain the functionality of the relay while incorporating it into a DC-operated control arrangement.

With a nominal operating voltage of 24 V DC, an operating range of 0.9 to 1.1 times the nominal voltage and a maximum ambient operating temperature of +40 °C, the Finder 026.9.024 provides a compact and convenient solution for compatible impulse relay installations. Its small dimensions and flexible connecting leads support integration into electrical enclosures and control wiring assemblies.

24V DC Control Integration for Finder Impulse Relay Systems

Impulse relays are commonly used in lighting installations where a single lighting circuit must be controlled from multiple pushbutton locations. A momentary electrical command changes the switching state of the impulse relay, allowing connected lighting loads to be switched without requiring conventional two-way or intermediate switch wiring. Finder 26 Series impulse relays provide this switching functionality in suitable residential, commercial and building services applications.

The Finder 026.9.024 extends the installation flexibility of compatible Finder 26 Series devices by enabling 24 V DC control of a compatible 24 V AC relay coil. This is particularly beneficial where a DC power supply is already present for control equipment or low-voltage pushbutton circuits. The adapter must be installed according to Finder's applicable wiring diagram and the selected relay's specifications; it does not replace the impulse relay or change the relay's load-switching ratings.

Typical Applications

• 24 V DC control of compatible Finder 26 Series impulse relays.
• Residential lighting control installations.
• Commercial building lighting systems.
• Low-voltage pushbutton switching circuits.
• Electrical installations with existing 24 V DC control supplies.
• Lighting circuits controlled from multiple pushbutton locations.
• Building automation and electrical control applications.
• Electrical control panels and distribution enclosures.
• Refurbishment of existing impulse relay installations.
• OEM electrical control assemblies.
• Integration of compatible AC-coil impulse relays into DC control systems.
