56.34.9.024.2074 Finder Miniature power relay 4 pole 12A DC 24V

Why Choose the Finder 56.34.9.024.2074 Industrial Power Relay?

The Finder 56.34.9.024.2074 is a 24 V DC industrial electromagnetic power relay from the Finder Series 56 range. Designed for industrial automation, electrical control panels and machinery applications, this four-pole relay provides flexible switching for multiple circuits using a single control signal.

Featuring a 4PDT / 4 CO (four changeover) contact configuration, the Finder 56.34 offers four independent sets of normally open and normally closed contacts. The Series 56.34 contact system has a 12 A rated current at 250 V AC for resistive loads, providing a higher contact rating than the 7 A Finder 55.34 relay family.

The 24 V DC coil, plug-in Faston terminals and compatibility with suitable Finder Series 96 sockets make this relay well suited to industrial control cabinets and OEM equipment. The 2074 variant belongs to the AgCdO contact option family; its exact indicator and accessory configuration should be confirmed against the manufacturer's full ordering code before purchase.

Key Advantages

High-Capacity Four-Pole Switching for Industrial Control Systems

The Finder 56.34.9.024.2074 is designed to operate four independent changeover contact sets from a 24 V DC control supply. When the relay coil is energised, the common contacts transfer from their normally closed positions to their normally open positions. When the coil supply is removed, the contacts return to their normal positions.

The 12 A contact rating makes the Finder Series 56.34 particularly useful for industrial applications requiring greater switching capacity than smaller auxiliary relay families. With four independent contact sets, one relay can perform multiple switching functions, such as controlling auxiliary equipment, providing status feedback, operating interlocks and switching separate control circuits. The 3,000 VA AC-1 rating applies to resistive loads; inductive, motor and high-inrush loads must be assessed against the relevant application-specific ratings.

The relay's plug-in Faston construction allows installation into a suitable Finder Series 96 socket, supporting straightforward replacement and maintenance. This makes it particularly useful in industrial control cabinets where service access and reliable electrical connections are important. Engineers should verify socket compatibility, coil suppression requirements, contact loading and the exact 2074 accessory configuration before finalising a design.

Finder Series 56 Compared with Series 55 Relays

Although the Finder Series 55 and Series 56 ranges are both used for industrial electromagnetic switching, they are designed around different contact ratings and socket systems. The Finder 56.34 offers four 12 A changeover contacts, while the Finder 55.34 offers four 7 A changeover contacts.

The Series 56.34 uses Finder Series 96-compatible sockets, whereas the Series 55.34 generally uses sockets from the Finder Series 94 family. These relay types should therefore not be assumed to be mechanically interchangeable, even when their coil voltages and contact arrangements are similar.

For new installations or replacement projects, the correct relay should be selected according to the coil supply, switching current, load characteristics, contact material, terminal arrangement and socket compatibility. The exact manufacturer's part number should be used when ordering a replacement.
