55.34.9.024.2070 Finder Miniature plugin relay 4 pole 7A DC 24V

Why Choose the Finder 55.34.9.024.2070 Industrial Plug-In Relay?

The Finder 55.34.9.024.2070 is a versatile 24 V DC industrial electromagnetic relay designed for dependable 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 changeover contacts with convenient plug-in construction and practical operational features.

Featuring a four-pole double-throw (4PDT / 4 CO) contact arrangement, the Finder 55.34.9.024.2070 allows four independent 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 signalling applications.

The relay features a 24 V DC coil, silver cadmium oxide (AgCdO) contacts and a lockable test button with LED indication. Its plug-in terminals enable installation into compatible Finder Series 94 sockets, supporting accessible wiring, convenient relay replacement and efficient maintenance within industrial control panels.

Reliable Four-Circuit Switching with LED Indication and Manual Testing

The Finder 55.34.9.024.2070 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 coil supply is removed, the relay returns to its original state, providing predictable switching behaviour for industrial control applications.

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

The relay's LED indicator and lockable test button provide useful commissioning and maintenance features. The LED assists with checking coil energisation, while the test button allows controlled manual actuation when appropriate. Its plug-in construction enables replacement without disconnecting the field wiring from a compatible socket. Manual testing must only be performed under suitable electrical safety procedures, as operating the test button can energise connected loads.
