Finder 486181101060SPA – 48 Series Relay interface modules

Why Choose the Finder 486181101060SPA DIN Rail Interface Relay Module?

The Finder 486181101060SPA, also identified as 48.61.8.110.1060SPA, is a compact 16 A DIN rail interface relay module designed for dependable electrical switching in industrial automation, control panels, machinery and building management systems. Part of the established Finder 48 Series, this complete relay interface combines an electromechanical changeover relay, a compatible socket, an LED status indicator and integrated coil protection in a convenient modular assembly.

Featuring a 110 V AC control coil and a single-pole double-throw (SPDT / 1 CO) contact configuration, the Finder 486181101060SPA provides a practical interface between an electrical control signal and a separate switched load. Its 16 A rated contact current and 250 V AC rated contact voltage make it suitable for a wide range of appropriately rated industrial and commercial switching applications.

This particular version incorporates silver nickel (AgNi) contacts, screw-clamp terminals, a plastic retaining clip and an LED plus varistor protection module. Its slim 15.8 mm width helps conserve valuable DIN rail space, while the removable relay construction simplifies maintenance and replacement. The Finder 486181101060SPA is therefore an excellent solution for control panel builders, industrial electricians, automation engineers and OEM equipment manufacturers requiring an accessible, space-efficient relay interface.

Efficient DIN Rail Switching with LED Indication and Varistor Protection

The Finder 486181101060SPA provides an effective interface between a 110 V AC control signal and an external electrical load. When the control coil is energised, the relay transfers its common contact from the normally closed terminal to the normally open terminal. When the coil is de-energised, the contact returns to its normal position. This changeover action allows the module to operate auxiliary loads, provide control feedback or switch between alternative circuit states.

The integrated LED indicator makes it easier for technicians to identify when the control voltage is present, supporting faster fault diagnosis and routine maintenance. The accompanying varistor protection module helps limit voltage transients generated during coil switching, reducing electrical disturbances in appropriately designed control systems. The LED indicates the control supply condition rather than independently confirming that the load contacts have changed state.

Its 15.8 mm slimline housing makes the Finder 48.61 interface particularly useful in control panels where DIN rail space is limited. The complete socket assembly provides accessible screw-clamp terminals, while the plastic retaining clip helps secure the removable relay. This combination supports efficient panel wiring, straightforward commissioning and convenient replacement when servicing equipment.

A Practical Interface Between Control Signals and Electrical Loads

The Finder 48 Series is designed to simplify the connection between control equipment and field devices. The Finder 486181101060SPA can be used to translate a compatible AC control signal into an isolated electromechanical contact output, allowing control systems to operate suitably rated electrical equipment without directly carrying the load current through the control circuit.

For industrial installations, the SPDT changeover contact provides flexibility in designing normally open and normally closed control functions. Typical uses include signalling, auxiliary interlocking, lighting control, equipment enable circuits and general-purpose load switching. Correct wiring, protective devices and load-specific switching ratings must be observed, particularly when switching motors, inductive loads or equipment with high inrush current.
