Four Changeover Contact Interfacing for Industrial Control

The Finder 96.74.0SMA is designed specifically for the Finder 56.34 relay, which provides four changeover contacts. This contact configuration is commonly referred to as 4 CO or 4PDT (four-pole, double-throw).

A four-changeover relay can control multiple independent switching circuits using a single relay coil. Each changeover contact provides a common terminal, a normally open terminal and a normally closed terminal, enabling engineers to configure different switching arrangements according to their control system requirements.

The socket's 14 connection positions accommodate the two relay coil connections and the twelve contact connections associated with the four changeover circuits. This makes it suitable for applications involving multiple auxiliary signals, equipment status indication, control interlocking and coordinated switching operations.

The Finder 96.74.0SMA itself is a passive relay socket and does not contain an independent switching mechanism. The electrical switching function is provided by the installed Finder 56.34 relay, which must be selected separately with the appropriate coil voltage and contact characteristics.

Although the socket is rated at 12 A and 250 V, the maximum permissible load of the complete assembly depends on the installed relay, the connected equipment and the operating conditions. Engineers should always use the lowest applicable rating when specifying the complete circuit.

Secure Plate-Clamp Screw Terminals and Flexible Mounting

The Finder 96.74.0SMA uses plate-clamp screw terminals, providing secure electrical connections for suitable industrial control conductors. This terminal design is well suited to control panel wiring where reliable conductor retention and straightforward inspection are important.

The specified 0.8 Nm terminal screw tightening torque helps ensure that conductors are secured correctly, while the 10 mm recommended stripping length provides a consistent basis for conductor preparation.

The socket supports suitable solid conductors up to 4 mm² and stranded conductors up to 4 mm² when using a single conductor per terminal. Permitted two-conductor arrangements depend on the conductor type and must follow Finder's terminal specifications.

For installation, the socket can be fitted to a standard 35 mm DIN rail in accordance with EN 60715. A panel mounting arrangement is also supported, giving electrical engineers and panel builders flexibility when designing machinery control enclosures.

The IP20 protection category makes the socket suitable for installation inside appropriately designed electrical cabinets. The enclosure must provide the necessary protection against moisture, dust, accidental contact and other environmental conditions.

Supplied with the Finder 096.71 Metal Retaining Clip

The SMA designation indicates that the Finder 96.74.0SMA is supplied with a metal retaining clip. For this 14-pin relay socket, the included accessory is the Finder 096.71.

The retaining clip helps hold the compatible Finder 56.34 relay securely in place. This is especially useful in industrial machinery and control equipment where vibration, mechanical movement or regular maintenance may affect plug-in components.

When the relay needs to be inspected or replaced, the clip can be released to allow the relay to be removed from the socket. The fixed wiring remains connected to the socket, helping reduce the time required for routine servicing.

The metal retaining clip is included with the socket, but the Finder 56.34 relay is not included and must be ordered separately.

Optional Finder 99.01 Coil Indication and EMC Suppression Modules

The Finder 96.74.0SMA supports selected Finder 99.01 coil indication and EMC suppression modules. These optional accessories can provide additional functionality for suitable relay control circuits.

Depending on the module selected, available functions include LED indication, diode suppression, varistor protection and RC suppression. Such modules can help indicate the presence of a coil control signal and manage electrical transients associated with relay operation.

The correct accessory must be selected according to the relay coil voltage, AC or DC supply type, polarity and electrical characteristics of the installation. A module intended for one supply voltage or coil configuration may not be suitable for another.

The standard Finder 96.74.0SMA is supplied with its metal retaining clip but does not include a 99.01 indication or suppression module. These accessories are selected and purchased separately.

Black Housing for Clearly Identified Control Panel Installations

The Finder 96.74.0SMA is the black housing version of the 96.74 relay socket family. The corresponding Finder 96.74SMA uses a blue housing.

Both variants are designed for compatible Finder 56.34 relays and provide the same general relay interface functionality. The housing colour can help engineers maintain consistency within an existing installation or distinguish relay interface groups in a control cabinet.

The black housing version is particularly useful when replacing an existing Finder 96.74.0 socket or when an equipment specification requires black relay bases.

When selecting a replacement, the complete part number should be checked to ensure the correct socket configuration, colour and retaining clip package are supplied.
