486180241060SMA Finder 1 CO Contacts 24V AC Modular Interface Relay with Green LED + varistor Indication

Why Choose the Finder 486180241060SMA 24 V AC 16 A DIN Rail Interface Relay Module?

The Finder 486180241060SMA, corresponding to the 48.61.8.024.1060SMA configuration, is a compact industrial interface relay module from the Finder Series 48 range. Designed for electrical control panels, industrial automation and machinery control systems, it provides an effective interface between low-voltage control equipment and electrical loads.

Featuring a 24 V AC operating coil and a 16 A single changeover contact, the module enables compatible control circuits to operate separately supplied electrical equipment. Its single-pole double-throw (SPDT) configuration provides normally open and normally closed switching functions, making it suitable for auxiliary control, equipment signalling and automation interfaces.

The Finder 48.61 module combines a plug-in electromechanical relay with a DIN rail mounting socket and screw-terminal connections. The SMA configuration provides a practical assembled interface solution for control cabinet installations, allowing straightforward wiring, convenient relay replacement and organised integration into industrial electrical systems.

Reliable Interface Switching for Industrial Control Panels

The Finder 486180241060SMA operates through an electromagnetic relay controlled by a nominal 24 V AC supply. When the coil is energised, the internal contact mechanism transfers the common terminal from the normally closed connection to the normally open connection. Removing the coil supply allows the relay to return to its original switching position.

This single-changeover contact arrangement provides flexibility for industrial control applications. It can be used to activate equipment, switch auxiliary circuits or provide control and status functions. The relay interface also provides galvanic separation between the control circuit and the switched contact circuit, supporting appropriate electrical isolation within the equipment design.

The DIN rail socket assembly simplifies installation in control cabinets, while the screw terminals allow field wiring to be connected without soldering. The plug-in relay can be replaced independently of the fixed wiring, helping reduce maintenance effort. Engineers should select suitable protection and consider load inrush current, inductive switching characteristics and conductor ratings when integrating the module into an electrical system.
