486180240060SMA Finder 1 CO Contacts 24V AC Modular Interface Relay with Green LED + varistor Indication

Why Choose the Finder 486180240060SMA Modular Interface Relay?

The Finder 486180240060SMA, also identified as 48.61.8.024.0060SMA, is a compact 24 V AC modular interface relay designed for industrial automation, electrical control panels and machinery control applications. Part of the established Finder 48 Series, this relay interface module combines an electromechanical switching relay with a socket assembly, providing a convenient solution for switching electrical loads through a low-voltage control circuit.

Featuring a single changeover contact (1 CO / SPDT) and a 16 A rated contact current, the Finder 48.61 relay interface family provides flexible switching for suitable industrial and commercial electrical loads. The 24 V AC control supply makes this configuration relevant to automation and control systems operating with AC control voltages. The changeover contact provides normally open and normally closed switching functions for control, signalling and auxiliary circuit applications.

The Finder 48.61.8.024.0060SMA is designed for DIN rail installation and features screw terminal connections for integration into electrical cabinets and control assemblies. Its modular construction includes a relay socket, allowing the relay element to be accessed for servicing or replacement. The compact 15.8 mm module width helps conserve valuable DIN rail space in densely populated control panels.

Compact DIN Rail Relay Interface for 24 V AC Control Systems

The Finder 48.61.8.024.0060SMA provides a practical interface between a 24 V AC control circuit and an electrical load. When the relay coil is energised, its electromechanical contact changes state, allowing the control circuit to operate a separate switching circuit. This arrangement is useful in industrial control panels, building automation systems and machinery where control signals must operate suitable external loads.

The single changeover contact offers a common terminal, a normally closed contact and a normally open contact. This provides flexibility for applications such as auxiliary switching, alarm signalling, equipment status indication and electrical interlocking. The appropriate contact arrangement should be selected according to the control circuit design and the required switching behaviour.

With a 16 A rated contact current, the Finder 48.61 relay interface family offers useful switching capacity for a compact DIN rail module. However, the permissible switching current depends on the load type and operating conditions. Resistive loads, inductive loads, motors and equipment with high inrush currents can impose different demands on relay contacts. The relevant manufacturer ratings should therefore be checked before specifying the module for a particular application.

The 15.8 mm-wide housing makes the Finder 486180240060SMA suitable for control panels where DIN rail space is limited. Its screw terminal connections provide accessible wiring points, while the supplied socket supports a modular installation arrangement. This can simplify panel assembly and servicing compared with designs where the relay is permanently integrated into an electronic circuit board.

The IP20 protection rating indicates protection against access with fingers and against solid objects of the specified size, but it does not provide protection against water ingress. The relay module should therefore be installed in a suitable electrical enclosure and used within the manufacturer's specified environmental and electrical operating conditions.

When selecting the Finder 48.61.8.024.0060SMA as a replacement, installers should verify the complete manufacturer part number, including the SMA suffix. Similar Finder 48 Series modules can differ in control voltage, connection method, socket configuration and additional functions. Matching the complete reference helps ensure the correct module is selected for the intended installation.
