55.34.9.024.0000T Finder Miniature plugin relay 4 pole 7A DC 24V

Why Choose the Finder 55.34.9.024.0000T Industrial Relay?

The Finder 55.34.9.024.0000T is a four-pole, general-purpose electromechanical relay from the Finder 55 Series, designed for dependable switching in industrial automation, electrical control panels and machinery applications. Featuring a 24 V DC operating coil and four changeover contacts (4 CO / 4PDT), this relay enables multiple independent electrical circuits to be controlled using a single switching signal.

The Finder 55.34 family combines compact plug-in construction with versatile multi-contact switching. Its four changeover contacts provide normally open and normally closed switching options, making the relay suitable for auxiliary control, signalling, interlocking and industrial equipment automation.

The 55.34.9.024.0000T configuration provides a practical solution for applications requiring a 24 V DC control supply, multiple contact outputs and convenient relay replacement. The T suffix identifies a variant intended for demanding applications, including railway-related installations, where the exact environmental and approval requirements should be checked against the manufacturer's documentation.

Reliable Four-Pole Changeover Switching

The Finder 55.34.9.024.0000T uses a 24 V DC electromagnetic coil to operate four changeover contact sets. When the coil is energised, each common contact transfers from its normally closed terminal to its normally open terminal. When the coil is de-energised, the contacts return to their normal positions.

This 4 CO / 4PDT configuration allows one relay to perform several related switching functions. For example, separate contacts may be allocated to equipment control, operating indication, auxiliary interlocking and signalling circuits.

The four contact sets are operated by the same electromagnetic mechanism, enabling coordinated switching while retaining separate contact terminals. This arrangement is particularly useful where several control circuits must respond to a common operating signal.

The permissible switching current depends on the load type, voltage, operating conditions and applicable contact rating. Engineers should verify the exact current and utilisation ratings for the T-suffix variant before specifying the relay for power-switching duties.

24 V DC Coil for Industrial Control Applications

The 24 V DC coil is suitable for industrial control systems designed around low-voltage DC supplies. It enables the relay to interface with appropriately rated control outputs, auxiliary control circuits and automation equipment.

Because this is a DC-coil relay, the supply must match the specified voltage and electrical requirements. The operating coil should not be connected directly to an AC supply.

Where the relay is controlled by electronic outputs, the output current capability and any required coil suppression should be assessed. Additional suppression components may influence release time and should be selected according to the control system requirements.

Plug-in Installation and Maintenance

The Finder 55.34.9.024.0000T is designed for use with a compatible Finder 94 Series relay socket. Its plug-in construction allows the relay to be removed and replaced without disconnecting the socket wiring, making it suitable for electrical panels where servicing and maintenance access are important.

Compatible sockets provide the electrical terminal connections and may support mounting on a standard DIN rail. The selected socket must accommodate the four-pole relay arrangement and the intended installation environment.

For railway or other demanding applications, the complete relay and socket assembly should be assessed against the relevant vibration, temperature, electrical and certification requirements. The T suffix alone should not be treated as confirmation of a particular system-level approval.
