Finder 55.34.8.230.2050 – 55 Series Industrial relays

Why Choose the Finder 55.34.8.230.2050 Miniature Industrial Relay?

The Finder 55.34.8.230.2050 is a versatile miniature industrial electromagnetic relay from the established Finder 55 Series, designed for electrical switching, automation and control applications. Featuring a 230 V AC nominal coil and four changeover contacts (4 CO / 4PDT), this relay provides a practical solution for controlling multiple electrical circuits from a single control signal.

The Finder 55.34 relay configuration combines four independent changeover contact sets with a compact plug-in design, making it suitable for industrial control panels, machinery and automation equipment. Each contact provides common, normally open and normally closed connections, allowing engineers to implement switching, signalling and circuit-interfacing functions within a single relay assembly.

With a 7 A nominal contact current rating associated with the Finder 55.34 configuration, the 55.34.8.230.2050 is suitable for appropriately rated electrical loads. Its 230 V AC coil makes it particularly useful in industrial control systems employing mains-derived AC control supplies, while its monostable electromagnetic operation provides predictable switching behaviour when the coil is energised or de-energised.

Key Advantages

• 230 V AC nominal coil: Suitable for compatible industrial AC control circuits.
• Four changeover contacts: Enables coordinated switching of four independent electrical circuits.

Reliable Four-Pole Switching for Industrial Control Systems

The Finder 55.34.8.230.2050 uses an electromagnetic coil to operate four mechanically linked changeover contact sets. When the appropriate 230 V AC control voltage is applied, the relay changes the position of all four contacts. When the coil supply is removed, the contacts return to their normal positions, providing conventional monostable relay operation.

The 4PDT contact arrangement allows a single control signal to perform several switching functions simultaneously. Each pole provides a common terminal that switches between normally closed and normally open contacts, making the relay useful for equipment control, electrical signalling, circuit changeover and automation interfaces.

The 7 A nominal contact rating provides switching capability for appropriately rated loads. However, actual permissible switching current depends on the applied voltage, load characteristics, inrush current, power factor and switching frequency. Inductive loads, motors and electronic power supplies may require additional consideration and suitable contact protection.

Its plug-in construction offers practical installation and maintenance benefits. When installed in a compatible Finder relay socket, the relay can be removed and replaced without disturbing the permanent socket wiring. This helps simplify equipment servicing, fault investigation and component replacement in industrial control panels.
