Why Choose the Finder 48.P6.8.024.1060SMA Interface Relay Module?
The Finder 48.P6.8.024.1060SMA is a compact, professional-grade 16 A electromechanical interface relay module from the Finder 48 Series, designed for dependable switching in industrial automation, PLC interfaces, machinery control and electrical panels. Featuring a 24 V AC operating coil, one changeover contact (1 CO / SPDT) and convenient Push-in terminal technology, this module provides a practical connection between electronic control systems and electrical loads.
The Finder 48.P6 range combines a plug-in electromechanical relay with a DIN-rail socket and coil indication module. Its 16 A rated contact current, 250 V AC nominal contact voltage and 4,000 VA AC-1 switching capacity support a wide range of appropriately rated industrial switching applications.
The SMA variant features a metal retaining clip that secures the relay within its socket. Together with the integrated supply-status indication, EMC coil suppression and compact 15.8 mm module width, this makes the Finder 48.P6.8.024.1060SMA particularly suitable for professional electrical control cabinets where secure relay retention, efficient wiring and straightforward maintenance are important.

The Finder 48.P6.8.024.1060SMA uses a 24 V AC electromagnetic coil to operate a single changeover contact. When the coil is energised, the common contact transfers from its normally closed position to its normally open position. When the coil is de-energised, the contact returns to its original state.
This switching arrangement allows an industrial controller, auxiliary control circuit or suitable PLC interface to operate a separate electrical load while maintaining galvanic separation between the coil and contact circuits. Its 16 A rated contact capacity makes the relay suitable for a variety of switching duties, provided the actual load characteristics fall within the manufacturer's specified limits.
The integrated supply-status indication provides a convenient visual reference during operation and troubleshooting. The EMC suppression module helps limit disturbances associated with electromagnetic coil switching, supporting reliable operation alongside sensitive electronic control equipment.
Important installation consideration: For switching currents above 10 A, Finder specifies that the contact terminals must be connected in parallel: 21 with 11, 24 with 14 and 22 with 12. This wiring arrangement must be followed when using the relay at its higher current ratings.
Fast Wiring with Push-in Terminals and Secure Metal Retention
The Finder 48.P6.8.024.1060SMA incorporates Push-in terminal technology, allowing suitable conductors to be connected efficiently without conventional screw-terminal tightening. This simplifies repetitive panel wiring and supports consistent installation practices in industrial electrical assemblies.
The SMA metal retaining clip secures the plug-in relay within the socket, helping maintain a stable assembly in industrial control applications. Unlike the SPA version, which uses a plastic retaining and instant-release clip, the SMA configuration employs a metal retaining clip.
The complete interface module mounts onto a standard 35 mm DIN rail. Its compact 15.8 mm width allows multiple interface relays to be installed side by side, while the removable relay provides convenient maintenance and replacement without rewiring the entire socket assembly.
