Reliable Electrical Switching for Industrial Automation
Industrial power relays such as the Finder 62.33.9.110.4070 provide a dependable method of controlling electrical loads using a separate DC control signal. When the relay's 110 V DC coil is energised, an electromagnetic mechanism operates the internal changeover contacts, transferring each circuit between its normally closed and normally open connections. This enables three separate electrical circuits to be controlled simultaneously while maintaining galvanic isolation between the coil and switched loads.
The Finder 62 Series is designed for industrial switching applications where dependable operation, flexible installation and straightforward maintenance are essential. The 62.33.9.110.4070 combines AgSnO2 contacts with an integrated LED indicator and suppression diode. The LED allows maintenance engineers to identify when the coil is energised, while the suppression diode helps reduce the inductive voltage spike generated when the DC coil is switched off.
A key feature of the 62.33.9.110.4070 is its lockable mechanical test button, which allows manual operation of the relay contacts during commissioning and troubleshooting. Its plug-in construction supports installation into compatible Finder sockets, helping minimise maintenance time and simplify component replacement. The relay is suitable for industrial control circuits, equipment interlocking, auxiliary switching and other applications operating within its specified electrical ratings.
