Reliable Multi-Circuit Switching for Industrial Automation

Electromagnetic relays such as the Finder 55.34.8.240.2000 provide electrically operated switching for industrial control circuits and connected equipment. When the 240 V AC coil is energised, the relay actuates its four changeover contact sets, allowing multiple electrical circuits to be switched simultaneously. When the coil is de-energised, the contacts return to their normal positions.

The 4PDT contact arrangement makes this relay particularly useful in applications requiring several switching operations from a single control signal. Its AgNi contact material, compact construction and plug-in mounting format support dependable operation and convenient maintenance in industrial automation, electrical interlocking, machine control and signalling applications.

Typical Applications

  • Industrial automation and machine control systems.
  • Electrical control panels and switchgear assemblies.
  • Multi-circuit switching and control logic.
  • Electrical interlocking and signalling circuits.
  • Motor control auxiliary circuits.
  • Industrial alarm and monitoring systems.
  • Building automation and equipment control.
  • Process control and instrumentation interfaces.
  • Electrical distribution and control cabinets.
  • OEM machinery and industrial panel building.

Frequently Asked Questions

What is the Finder 55.34.8.240.2000 used for?

The Finder 55.34.8.240.2000 is a general-purpose electromagnetic relay designed for switching multiple electrical circuits in industrial automation, machinery control, electrical panels and signalling applications.

What coil voltage does the Finder 55.34.8.240.2000 require?

This relay operates with a 240 V AC nominal coil supply at 50/60 Hz. It is designed for compatible AC control circuits rather than direct DC coil operation.

How many contacts does this Finder relay have?

The relay features four changeover contacts (4 CO), also described as a 4PDT configuration. This allows four separate changeover circuits to be operated by a single relay coil.

What is the contact current rating of this relay?

The Finder 55.34.8.240.2000 has a 7 A rated contact current. The permissible switching load depends on the circuit voltage, load characteristics and applicable contact ratings.

What contact material is used in the Finder 55.34.8.240.2000?

This model uses silver nickel (AgNi) contacts, a cadmium-free contact material commonly used in electromagnetic relays for reliable electrical switching.

How is the Finder 55.34.8.240.2000 installed?

The relay uses a plug-in terminal arrangement and is designed for installation in compatible Finder 94 Series relay sockets, enabling convenient mounting and replacement in electrical control panels.
