65.31.9.024.4000 Finder Power relay 1NO 30A DC 24VNO

Why Choose the Finder 65.31.9.024.4000 Industrial Power Relay?

The Finder 65.31.9.024.4000 is a robust 20 A industrial electromagnetic power relay designed for reliable electrical switching in machinery, automation, power management and industrial control equipment. Part of the established Finder 65 Series, this model features a 24 V DC operating coil and a 1 normally open + 1 normally closed (1 NO + 1 NC) contact arrangement, providing versatile switching functionality for industrial electrical applications.

The relay incorporates two complementary contact functions operated by a common electromagnetic mechanism. When the coil is energised, the normally open contact closes while the normally closed contact opens. This arrangement is particularly useful for applications requiring coordinated switching, electrical interlocking, equipment status indication or the simultaneous control of complementary electrical circuits.

Featuring rear flange mounting and Faston 250 quick-connect terminals, the Finder 65.31.9.024.4000 is designed for practical integration into industrial electrical assemblies. Its 20 A rated contact current, 250 V AC rated contact voltage and robust electromechanical construction make it suitable for appropriately rated power-switching and auxiliary control applications.

Key Advantages

• 20 A rated contact current for compatible industrial power-switching applications.
• 24 V DC operating coil suitable for low-voltage DC control systems.

Reliable Complementary Switching for Industrial Control Systems

The Finder 65.31.9.024.4000 provides an effective interface between 24 V DC control circuits and industrial electrical loads. When the relay coil is energised, its electromagnetic mechanism operates the normally open and normally closed contacts together, allowing complementary switching functions to be performed from a single control signal.

The 1 NO + 1 NC contact arrangement is particularly useful for equipment requiring coordinated circuit operation. One circuit can be connected while another is disconnected, supporting functions such as electrical interlocking, machinery sequencing, auxiliary control and equipment status indication. The relay's 20 A rated contact current also makes it suitable for appropriately rated power-switching applications.

Its rear flange mounting arrangement and Faston 250 terminals provide a practical installation solution for industrial machinery and OEM electrical equipment. Correct selection of contact loading, switching duty, circuit protection and mechanical installation is essential, particularly for motors, inductive loads and equipment with high starting currents.

Typical Applications

• Industrial automation and electrical control panels.
• 24 V DC machinery control systems.
• Electrical interlocking and sequencing circuits.
• Industrial auxiliary load switching.
• Power distribution and management equipment.
• Industrial washing and processing machinery.
• Heating equipment, boilers and burner control systems.
• Generator and backup power control equipment.
• Manufacturing and process control systems.
• OEM electrical equipment requiring complementary NO and NC contacts.
