56.32.9.024.4090 Finder Miniature power relay Plugin 2p 12A DC24V

Why Choose the Finder 56.32.9.024.4090 Miniature Power Relay?

The Finder 56.32.9.024.4090 is a 12 A miniature industrial power relay designed for reliable electrical switching in industrial automation, machinery control and electrical panel applications. Part of the established Finder 56 Series, this plug-in relay combines a 24 V DC operating coil, two changeover contacts (2 CO / DPDT) and silver tin oxide contact technology in a compact, serviceable design.

The relay's silver tin oxide (AgSnO2) contacts provide good resistance to contact welding and are particularly useful for compatible applications involving demanding switching conditions. With a 12 A rated contact current, 250 V AC rated contact voltage and 3000 VA AC1 switching capacity, the Finder 56.32.9.024.4090 is suitable for a broad range of industrial resistive loads, subject to the manufacturer's operating limits.

A distinguishing feature of the .4090 configuration is its combination of AgSnO2 contacts, a lockable test button and an LED indication circuit with an integrated diode. Unlike the non-polarised double-LED arrangement used in certain other DC variants, the .0090 option incorporates a diode circuit and therefore requires the correct DC coil polarity. The relay is designed for use with compatible Finder 96 Series sockets, allowing straightforward installation and replacement.

Specification note: The contact ratings and standard coil characteristics are taken from Finder's published 56 Series technical information. The .4090 suffix is decoded using Finder's ordering system as AgSnO2 contacts with a lockable test button, LED and diode. The exact complete part number was not independently located in a dedicated manufacturer product listing; confirm the terminal diagram and any variant-specific ratings before installation.

Integrated Diode Protection, LED Indication and Silver Tin Oxide Contacts

The Finder 56.32.9.024.4090 uses a 24 V DC electromagnetic coil to operate two changeover contact sets. When the coil is energised, each contact transfers from its normally closed position to its normally open position. When coil power is removed, the relay returns to its normal state. This arrangement allows two independent circuits to be controlled simultaneously using one DC control signal.

The .4090 version includes an LED and integrated diode. The LED provides a visible indication when the coil circuit is energised, while the diode suppresses the voltage transient generated when the coil is switched off. This can help protect compatible electronic switching devices from inductive voltage spikes. Because the diode makes the coil connection polarity-sensitive, the positive supply must be connected to the terminal specified by Finder. Incorrect polarity can create an unintended current path through the diode and potentially damage the control circuit.

The relay's silver tin oxide contacts are designed for industrial switching applications where resistance to contact welding is beneficial. They can be useful for appropriately rated loads with challenging current characteristics, but the actual switching duty must be evaluated carefully. Loads such as motors, solenoids, LED drivers and switched-mode power supplies may have starting or inrush currents substantially higher than their steady-state current.

The lockable test button provides a convenient way to operate the relay manually during controlled commissioning and maintenance. The relay's plug-in design also allows it to be installed in a compatible Finder 96 Series socket, making replacement and servicing more straightforward. Manual operation must never be used as a substitute for proper electrical isolation or safe maintenance procedures.
