Finder 486181100060SMA – 48 Series Relay interface modules

Why Choose the Finder 486181100060SMA 110 V AC Interface Relay?

The Finder 486181100060SMA, also identified as 48.61.8.110.0060SMA, is a compact 110 V AC modular interface relay designed for industrial automation, electrical control panels, machinery and auxiliary switching applications. Part of the established Finder 48 Series, this relay interface module combines an electromechanical relay with a DIN rail socket assembly, providing a practical solution for controlling electrical loads through a separate control circuit.

Featuring a single changeover contact (1 CO / SPDT) with a 16 A rated contact current, the Finder 48.61.8.110.0060SMA offers flexible switching for suitable electrical loads. Its 110 V AC coil is designed for 50/60 Hz control supplies, while the changeover contact provides normally open and normally closed switching functions. This makes the module suitable for control, signalling, interlocking and equipment interface applications.

The Finder 486181100060SMA features DIN rail mounting, screw terminal connections, an LED status indicator and a varistor protection function. Its compact 15.8 mm module width helps conserve space in electrical cabinets, while the modular relay-and-socket construction supports convenient installation, inspection and maintenance. The module is particularly useful for electrical contractors, industrial maintenance engineers, control panel builders and automation system manufacturers.

Reliable 110 V AC DIN Rail Relay Interface for Industrial Control

The Finder 48.61.8.110.0060SMA provides a convenient interface between a 110 V AC control circuit and a separate electrical load circuit. When the relay coil is energised, the electromechanical contact changes state, allowing the control signal to operate connected equipment within the specified contact ratings. This arrangement is useful in industrial automation, machine control, building services and electrical distribution systems.

The single changeover contact includes a common terminal, a normally closed contact and a normally open contact. When the relay operates, the common connection transfers between the normally closed and normally open positions. This provides flexibility for auxiliary switching, status indication, alarm circuits and electrical interlocking functions.

The 16 A rated contact current provides substantial switching capability within a compact modular relay. However, permissible switching current depends on the load characteristics, operating voltage and switching frequency. Inductive loads, motors, contactor coils and equipment with high inrush currents may require additional consideration. The relevant AC1, AC15, motor or DC load ratings should always be checked against the Finder technical documentation before specifying the module.

The integrated LED indicator provides a useful visual indication of the relay control state, assisting engineers during commissioning, inspection and fault-finding. The varistor protection function is designed to help manage voltage transients associated with switching the AC relay coil. These features make the module particularly useful in industrial control cabinets where clear operational feedback and practical electrical protection are important.

Designed for DIN rail installation, the Finder 486181100060SMA features a compact 15.8 mm width and screw terminal connections. The complete relay-and-socket arrangement provides accessible wiring and supports straightforward maintenance. Its modular construction is particularly useful where equipment must be serviced without replacing an entire control assembly.

The IP20 protection rating makes the relay suitable for installation within an appropriately designed electrical enclosure. It does not provide water ingress protection, so the surrounding cabinet must provide any additional environmental protection required by the installation. Electrical connections, conductor sizes, supply voltage and load characteristics must comply with the manufacturer's instructions and applicable electrical installation requirements.

For replacement applications, the complete Finder 48.61.8.110.0060SMA reference should be checked carefully. Other Finder 48.61 modules may have different coil voltages, contact materials, terminal configurations or accessories. In particular, this 110 V AC version must not be confused with the 24 V AC Finder 48.61.8.024.0060SMA, as the two products require different control supply voltages.
