Reliable Multi-Circuit Switching for Industrial Automation

Industrial electromechanical relays such as the Finder 55.34.8.024.2040 provide a convenient way to control several electrical circuits from a single input signal. When the 24 V AC coil is energised, the relay's electromagnetic mechanism changes the position of its four changeover contacts, allowing connected circuits to be switched according to the control system's requirements.

The Finder 55 Series is designed for general-purpose switching applications in machinery, electrical panels and industrial automation. Its plug-in design allows installation into compatible relay sockets, simplifying servicing and replacement without extensive changes to existing control wiring.

With four changeover contact sets rated at 7 A, this relay is particularly useful where a single control command must operate multiple auxiliary circuits. Typical functions include electrical interlocking, status indication, control sequencing and switching of appropriately rated loads. Contact ratings and load characteristics should be considered when selecting the relay for a particular application.

Typical Applications

  • Industrial electrical control panels and switchgear assemblies.
  • Machinery automation and auxiliary control circuits.
  • PLC interface and relay-based control systems.
  • Electrical interlocking and sequential switching arrangements.
