62.33.9.024.4060 Finder Power relay 3 pole 16A DC 24V

Why Choose the Finder 62.33.9.024.4060 Power Relay?

The Finder 62.33.9.024.4060 is a high-performance 16 A three-pole electromechanical power relay designed for dependable electrical switching in industrial automation, machinery control and electrical control panels. Part of the established Finder 62 Series, this relay combines a 24 V DC operating coil, three changeover contacts (3 CO / 3PDT), an integrated LED indicator and a built-in flyback diode to provide reliable switching with convenient coil-status indication and transient suppression.

Featuring three independent changeover contacts, the Finder 62.33.9.024.4060 enables three separate electrical circuits to be switched simultaneously using a single 24 V DC control signal. Each contact set provides common, normally open and normally closed connections, offering flexibility for electrical interlocking, auxiliary switching, signalling and multi-circuit control. Its silver tin oxide (AgSnO2) contacts offer good resistance to contact welding and support dependable operation with appropriately rated industrial electrical loads.

A distinguishing feature of the 62.33.9.024.4060 is its combination of an LED coil indicator and integrated suppression diode. The LED provides visual confirmation when the relay coil is energised, while the diode helps limit the voltage transient generated when the DC coil is switched off. This is particularly useful in control systems incorporating PLC outputs, electronic controllers and other suitably rated DC switching devices. Combined with Faston 187 quick-connect terminals, compatibility with the appropriate Finder 92 Series socket and a robust industrial relay construction, this model offers a practical solution for electrical engineers, automation specialists and maintenance professionals.

Reliable 24 V DC Switching with Integrated LED and Flyback Diode

The Finder 62.33.9.024.4060 operates through an electromagnetic switching mechanism. When the 24 V DC coil is energised with the correct polarity, the internal armature transfers all three changeover contacts from their normally closed positions to their normally open positions. This allows one DC control signal to operate three independent electrical circuits. When the coil supply is removed, the contacts return to their normal positions, providing conventional monostable operation.

The integrated LED indicator provides visual confirmation that the coil is energised. This is useful during commissioning, maintenance and fault-finding because technicians can quickly identify whether the relay is receiving its intended control signal. The LED indicates the coil's electrical status rather than independently verifying that every contact has transferred correctly.

The built-in flyback diode provides an additional benefit for DC control applications. When a relay coil is switched off, the collapsing magnetic field can generate a high-voltage transient. The integrated diode provides a path for the coil current to decay, helping to limit the transient voltage seen by the switching device. This can be particularly useful when the relay is controlled by an appropriately rated PLC transistor output or electronic control circuit.

Because the relay contains a diode, correct coil polarity is essential. The positive supply must be connected to the manufacturer's designated positive coil terminal, and the negative supply to the designated negative terminal. Reversing the polarity can forward-bias the suppression diode and cause excessive current to flow. The diode can also increase relay release time compared with an unsuppressed coil, so applications requiring precisely controlled contact release should account for this behaviour.

Finder 62.33.9.024.4060 vs Other 24 V DC Versions

The Finder 62.33.9.024.4060 is particularly suitable when an application requires both visual coil indication and integrated DC coil suppression. The closely related 62.33.9.024.4000 provides the standard relay configuration without these integrated electronic features. For installations requiring a lockable manual test button in addition to an LED and diode, the 62.33.9.024.4070 offers an alternative configuration.

When replacing an existing relay, confirm the full manufacturer part number rather than matching only the coil voltage and contact arrangement. Differences in LED indication, diode suppression, manual testing and terminal compatibility can affect installation and control-circuit operation.
