Why Choose the Finder 55.34.9.024.2094 Industrial Relay?
The Finder 55.34.9.024.2094 is a high-performance four-pole changeover (4PDT) industrial electromagnetic relay designed for reliable switching in industrial automation, electrical control panels and machinery applications. As part of the established Finder 55 Series miniature general-purpose relay range, it combines versatile contact switching, compact construction and convenient plug-in installation.
Featuring a 24 V DC operating coil and four changeover contacts rated at 7 A, this relay enables multiple independent electrical circuits to be controlled through a single electromagnetic switching device. The 55.34.9.024.2094 incorporates a lockable test button, LED status indicator, integrated suppression diode and mechanical status indicator, providing enhanced functionality for commissioning, diagnostics and maintenance.
The relay uses silver-cadmium oxide (AgCdO) contact material and provides a 250 V AC rated contact voltage with a nominal AC1 switching capacity of 1,750 VA. Its plug-in design supports straightforward installation into compatible Finder relay sockets, making it an excellent choice for PLC interfaces, electrical interlocking, industrial control circuits and general-purpose switching applications.

Reliable DC Relay Switching with Enhanced Status Indication
The Finder 55.34.9.024.2094 operates by applying a 24 V DC control voltage to its electromagnetic coil. When energised, the relay changes the position of its four changeover contacts, allowing connected electrical circuits to be switched simultaneously. When the coil is de-energised, the contacts return to their normal positions.
The integrated LED indicator, mechanical status indicator and lockable test button provide practical advantages during installation, commissioning and maintenance. The LED indicates when the coil is energised, while the mechanical indicator provides a visual indication of the relay's physical operating state. The lockable test button allows manual actuation for functional testing under appropriate electrical safety procedures.
An integrated suppression diode helps reduce voltage transients generated when the electromagnetic coil is switched off, supporting compatibility with electronic control equipment. Because the diode is polarity-sensitive, the positive DC supply must be connected to terminal A1/13 and the negative supply to the corresponding return terminal.
The relay's AgCdO contacts provide dependable switching performance for industrial control loads. Combined with its plug-in construction and four independent changeover contacts, the Finder 55.34.9.024.2094 offers a practical solution for PLC-controlled machinery, auxiliary switching and industrial automation systems.
