Reliable Industrial Switching and PLC Interface Performance
The Finder 48.61.7.024.1050SPA operates using a 24 V DC electromagnetic coil to control a single changeover contact. When the coil is energised, the relay transfers its contact from the normally closed position to the normally open position. When the coil is de-energised, the contact returns to its original state.
This switching arrangement enables an electronic controller or PLC to operate a separate electrical load while maintaining galvanic isolation between the control and switched circuits. The 16 A contact rating supports a range of industrial switching applications, subject to the electrical characteristics of the connected load.
The module's integrated green LED provides convenient visual confirmation of coil energisation, while the suppression diode helps limit voltage transients when the relay is switched off. Because the suppression circuit is polarity-sensitive, the positive DC supply must be connected to the designated A1 terminal.
Its 15.8 mm slimline construction allows efficient use of DIN-rail space, while the screw-terminal socket and replaceable plug-in relay simplify installation, testing and maintenance. For switching currents above 10 A, the contact terminals must be connected in parallel as specified in Finder's installation documentation.
