Why Choose the Finder 56.34.9.024.0000 Miniature Power Relay?
The Finder 56.34.9.024.0000 is a robust 12 A miniature industrial power relay designed for reliable electrical switching in industrial automation, machinery control and electrical distribution equipment. Part of the established Finder 56 Series, this general-purpose electromechanical relay features a 24 V DC operating coil and four changeover contacts (4 CO / 4PDT), enabling four independent electrical circuits to be controlled from a single relay.
With a 12 A rated contact current, 250 V AC rated contact voltage and silver nickel (AgNi) contacts, the Finder 56.34.9.024.0000 provides versatile switching performance for appropriately rated industrial loads. Its 490 Ω nominal coil resistance, approximately 49 mA coil current and 1.2 W DC coil consumption make it suitable for integration into compatible 24 V DC control systems.
Designed for convenient installation and maintenance, this four-pole plug-in power relay features a lockable test button and mechanical status indicator. It can be installed using appropriately selected Finder 96 Series relay sockets, including suitable DIN rail mounting arrangements. Its combination of high-current contacts, multiple switching poles and replaceable construction makes it a practical choice for OEM equipment, industrial control panels and electrical maintenance applications.

Technical note: The 12 A contact rating applies to appropriately specified switching conditions. The maximum voltage rating and resistive-load switching capacity must not be interpreted as permission to switch every load type at those limits. Motors, contactors, solenoids, LED drivers and other inductive or high-inrush loads require separate assessment against Finder's load-specific ratings.
Four-Pole Power Switching for Industrial Automation
The Finder 56.34.9.024.0000 uses a 24 V DC electromagnetic coil to control four independent changeover contact sets. Each contact provides a common terminal, a normally closed connection and a normally open connection. When the coil is energised, all four contact sets transfer to their operated positions. Removing the coil supply returns the contacts to their normal positions, providing conventional monostable relay operation.
This four-pole changeover arrangement is particularly useful in industrial control systems where a single command must operate multiple functions. For example, separate contacts can be assigned to auxiliary switching, equipment status indication, control interlocking and other suitably rated circuits. The four contacts provide electrical switching flexibility, although they are mechanically linked and must not be treated as independently controlled relays.
The AgNi contact material offers established performance for general-purpose electrical switching. Its cadmium-free composition supports modern industrial equipment design. When selecting the relay for applications involving significant starting currents, repetitive switching or inductive loads, designers should verify the relevant utilisation category, contact endurance and protective measures rather than relying solely on the nominal 12 A rating.
Convenient Plug-In Installation and Maintenance
The Finder 56.34.9.024.0000 is designed for installation using a compatible Finder 96 Series socket. This arrangement allows the relay to be removed and replaced without disconnecting permanent wiring or desoldering components. Depending on the socket selected, the assembly can be installed in a control panel or on a DIN rail.
A lockable test button allows controlled manual operation during suitable commissioning and maintenance procedures, while the mechanical indicator helps technicians identify the relay's contact state. Manual testing can change the condition of connected electrical circuits, so the test facility must only be used when equipment operation is safe and authorised.
