55.34.8.024.2030 Finder Miniature plugin relay 4 pole 7A 24V

Why Choose the Finder 55.34.8.024.2030 Industrial Plug-In Relay?

The Finder 55.34.8.024.2030 is a 24 V AC industrial electromagnetic relay designed for dependable multi-circuit switching in industrial automation, machinery controls and electrical control panels. Part of the Finder Series 55 range, this miniature general-purpose relay combines four independent changeover contacts with convenient plug-in mounting.

Featuring a four-pole double-throw (4PDT / 4 CO) contact configuration, the Finder 55.34.8.024.2030 allows four separate electrical circuits to be controlled from one 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, signalling and industrial equipment control.

The relay features a 24 V AC, 50/60 Hz coil, silver cadmium oxide (AgCdO) contacts and an integrated LED indicator for visual indication of coil energisation. Its plug-in construction supports installation into compatible Finder Series 94 sockets, helping simplify control panel wiring and relay replacement.

Reliable Four-Circuit Switching with LED Status Indication

The Finder 55.34.8.024.2030 operates using a 24 V AC electromagnetic coil that controls 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 supply is removed, the relay returns to its original state, providing predictable switching behaviour.

The 4PDT contact configuration is useful for applications where multiple control functions must operate from one signal. Engineers can use the relay for auxiliary switching, equipment status signalling, electrical interlocking and simultaneous control of separate circuits. Each contact set offers a 7 A resistive AC rating, although inductive, capacitive and high-inrush loads require assessment against the relevant manufacturer ratings.

The integrated LED indicator helps maintenance personnel identify when the relay coil is receiving an energising supply. Its plug-in construction also allows the relay to be removed from a compatible socket without disconnecting the socket's field wiring. These features make the Finder 55.34.8.024.2030 a practical choice for industrial control panels where accessible maintenance and clear operational indication are important.
