55.34.9.024.2074 Finder Miniature plugin relay 4 pole 7A DC 24V

Why Choose the Finder 55.34.9.024.2074 Industrial Plug-In Relay?

The Finder 55.34.9.024.2074 is a versatile 24 V DC industrial electromagnetic relay designed for reliable multi-circuit switching in industrial automation, machinery controls and electrical control panels. Part of the established Finder Series 55 range, this miniature general-purpose relay combines four independent changeover contacts with a practical plug-in design and integrated diagnostic features.

Featuring a four-pole double-throw (4PDT / 4 CO) contact arrangement, the Finder 55.34.9.024.2074 allows four separate electrical circuits to be controlled using a single electromagnetic coil. Each contact set is rated at 7 A at 250 V AC for resistive loads, making the relay suitable for auxiliary switching, electrical interlocking, equipment control and industrial signalling applications.

The relay features a 24 V DC coil, silver cadmium oxide (AgCdO) contacts, a lockable test button, dual LED indication and a mechanical contact-position indicator. Its plug-in construction supports installation into compatible Finder Series 94 sockets, helping simplify control panel wiring, commissioning and maintenance.

Reliable Four-Circuit Switching with Enhanced Visual Indication

The Finder 55.34.9.024.2074 uses a 24 V DC electromagnetic coil to operate four independent changeover contact sets. When the coil is energised, all four contacts transfer from their normally closed positions to their normally open positions. When the control voltage is removed, the relay returns to its original state, providing predictable switching behaviour for industrial control systems.

The 4PDT contact configuration enables engineers to control several auxiliary circuits from one signal. This makes the relay particularly useful for electrical interlocking, equipment status indication, alarm signalling and simultaneous switching of multiple control functions. Each contact set has a 7 A resistive AC rating, although inductive, capacitive and high-inrush loads must be assessed against the manufacturer's relevant switching specifications.

The 2074 configuration adds practical maintenance features through its dual LED indication, lockable test button and mechanical indicator. The LEDs provide visual feedback when the coil is energised, while the mechanical indicator allows the operating position to be checked visually. The test button supports controlled manual actuation during commissioning and fault-finding. When fitted into a compatible socket, the relay can be replaced without disconnecting the socket's field wiring.
