Finder 55.34.8.230.2000 – 55 Series Industrial relays

Why Choose the Finder 55.34.8.230.2000 Industrial Relay?

The Finder 55.34.8.230.2000 is a reliable 7 A, 230 V AC plug-in industrial relay designed for electrical switching in automation systems, control panels and industrial machinery. Part of the Finder Series 55 general-purpose relay range, this four-pole electromechanical relay combines flexible multi-circuit control with a compact, socket-mounted design.

Featuring four changeover contacts (4PDT, 4 CO), the Finder 55.34.8.230.2000 can switch four independent electrical circuits using a single electromagnetic coil. Its 230 V AC coil is suitable for compatible 50/60 Hz control supplies, while its 7 A rated contacts at 250 V AC support a variety of industrial switching applications.

This particular variant features silver cadmium oxide (AgCdO) contacts, providing a robust contact system for electrical load switching. Its plug-in terminal arrangement allows installation into compatible Finder Series 94 relay sockets, making it a practical choice for electrical panel builders, maintenance engineers and OEM equipment manufacturers.

Key Advantages

• Four changeover contacts (4PDT, 4 CO) enable independent switching of four electrical circuits.
• 230 V AC nominal coil voltage supports compatible mains-voltage control systems.

Flexible Four-Pole Switching for Industrial Automation

Electromechanical relays such as the Finder Series 55 use an electromagnetic coil to operate mechanically linked electrical contacts. When the coil is energised, all four changeover contacts transfer from their normally closed positions to their normally open positions. When the coil supply is removed, the contacts return to their original states. This enables one control signal to operate four separate electrical circuits while maintaining galvanic isolation between the coil and contact systems.

The Finder 55.34.8.230.2000 is particularly suitable for industrial control systems requiring multiple switching functions from a single relay. Its 4PDT contact configuration supports auxiliary control, electrical interlocking, signalling and equipment switching, while the 230 V AC coil allows operation from an appropriately rated AC control supply.

Its plug-in construction enables convenient installation into a compatible relay socket, making maintenance and replacement easier than with permanently soldered devices. Suitable Finder Series 94 sockets provide mounting options for industrial control panels, including 35 mm DIN rail installations. Engineers should consider load characteristics, switching frequency, contact protection and socket ratings when specifying the relay, particularly for inductive or high-inrush loads.

Typical Applications

• Industrial automation and process control systems.
• Electrical control panels and relay interface assemblies.
• PLC-controlled auxiliary switching circuits.
• Industrial machinery and OEM equipment.
• Building automation and building management systems.
• Electrical interlocking and multi-circuit control.
• HVAC equipment and ventilation control circuits.
• Control circuit switching and status signalling.
• Maintenance-friendly plug-in relay installations.
