Finder 93.01.8.240 – 93 Series Sockets for 34 Series relays

Finder 93.01.8.240 Relay Socket – 230 V AC, 6.2 mm Slimline DIN Rail Mounting, Screw Terminals, LED and EMC Suppression

The Finder 93.01.8.240 is a professional 230 V AC DIN rail relay socket designed for use with compatible Finder 34 Series miniature relays. Part of the Finder 93 Series, this compact interface socket combines convenient relay mounting, secure electrical connections and integrated indication and suppression circuitry in a slimline housing.

Featuring a 6.2 mm-wide blue housing, five-pin relay connection, screw terminals and a built-in LED indication and EMC suppression circuit, the Finder 93.01.8.240 is particularly suitable for industrial automation, PLC interface circuits, electrical control cabinets and machinery control systems.

The socket is designed for a 230 V AC nominal control supply and supports compatible Finder 34.51 relay arrangements. Its integrated retaining and extraction lever makes relay installation and replacement straightforward, helping simplify maintenance in densely populated electrical panels.

Important: The Finder 93.01.8.240 is a relay socket, not a complete switching relay. A suitable relay must be installed separately, and the current rating of the completed assembly depends on both the socket and the selected relay.

How the Finder 93.01.8.240 Relay Socket Works

The Finder 93.01.8.240 provides the mechanical and electrical interface between a compatible Finder miniature relay and the external control wiring.

During installation, the socket is mounted onto a suitable 35 mm DIN rail. The control supply and output circuit conductors are connected to the socket's screw terminals. A compatible Finder 34 Series relay is then inserted into the five-pin socket connection.

When the relay coil receives its specified control voltage, the relay changes the state of its switching contacts. The socket provides the connections between those relay contacts and the external electrical circuit.

The socket's integrated LED indication circuit provides a convenient visual reference when the coil control circuit is energised. This can help engineers identify active control signals during commissioning and troubleshooting.

The integrated EMC suppression circuit helps manage switching disturbances associated with the relay coil. This is particularly useful in automation systems where electronic controllers, PLCs and other sensitive components are installed nearby.

The actual contact arrangement and electrical switching characteristics depend on the fitted relay. The socket itself does not provide independent switching contacts.

Integrated LED Indication and EMC Suppression

A key advantage of the Finder 93.01.8.240 is its integrated combination of LED indication and electromagnetic compatibility suppression.

When an electromechanical relay coil is switched, the changing magnetic field can generate an electrical transient. If not adequately managed, such disturbances may interfere with nearby electronic equipment.

The suppression circuit incorporated into the socket helps reduce these unwanted effects. This can simplify panel construction by avoiding the need to install a separate external suppression component in suitable applications.

The LED indication feature also assists maintenance technicians by providing an immediate visual reference for the coil control circuit.

Important: The LED indicates the state of the associated control circuit; it does not prove that the relay contacts have operated correctly or that the connected load is energised. Electrical testing should be used where confirmation is required.

230 V AC Control Voltage – AC-Only Version

The Finder 93.01.8.240 is designed for 230 V AC nominal control circuits. The manufacturer socket selection information identifies the 93.01.8.240 version for 220–240 V AC applications.

This distinction is important because the Finder 93 Series includes other socket variants intended for different control voltages and DC supplies.

The 93.01.8.240 should not be treated as a universal AC/DC socket. For DC control supplies, the appropriate DC-rated socket variant must be selected.

For example, the Finder 93.01.7.060 is associated with 48–60 V DC control circuits, whereas the 93.01.8.240 is intended for 230 V AC applications.

Correct matching of the socket, relay coil voltage and supply type is essential to ensure proper operation and avoid damage to the indication and suppression circuitry.

Slimline 6.2 mm Housing for High-Density Control Cabinets

The Finder 93.01.8.240 features an exceptionally narrow 6.2 mm-wide housing, allowing multiple relay interface assemblies to be installed side by side on a DIN rail.

This compact construction is particularly useful in industrial control cabinets where numerous PLC signals, auxiliary control circuits or individual switching channels must be accommodated within a limited space.

The blue housing provides a distinctive visual appearance, while the retaining and extraction lever helps keep the relay securely installed.

The modular socket arrangement also simplifies servicing. A compatible relay can be removed and replaced without disturbing the external wiring, provided the electrical circuit has first been safely isolated.

DIN Rail Installation and Wiring

The Finder 93.01.8.240 is designed for installation on a standard 35 mm DIN rail. Its screw terminal connections provide a conventional wiring method for electrical engineers and industrial control panel builders.

The socket is intended for use with compatible Finder 34 Series relays. The exact relay should be selected according to the required coil voltage, switching current, contact configuration and application requirements.

For a typical installation, the socket is secured to the DIN rail, the control and load wiring is connected to the appropriate terminals, and the compatible relay is inserted and secured using the retaining lever.

The manufacturer's wiring diagram must be followed to identify the correct coil and contact terminal connections. The socket should be installed inside a suitable electrical enclosure with appropriate circuit protection.

Safety note: The 93.01.8.240 is intended for mains-voltage AC control circuits. Installation, testing and maintenance must be carried out by competent personnel using appropriate safe isolation procedures.
