Why Choose the Finder 48.52.8.120.5060SMA Relay Interface Module?
The Finder 48.52.8.120.5060SMA is a compact 8 A industrial relay interface module from the Finder 48 Series, designed for electrical switching and signal interfacing in industrial automation systems, PLC control panels and machinery. Combining an electromechanical relay with a DIN rail mounting socket, this interface module provides a convenient solution for connecting control circuits to compatible electrical loads.
Featuring a 120 V AC nominal operating coil and two changeover contacts (2 CO / DPDT), the Finder 48.52.8.120.5060SMA allows two independent electrical circuits to be switched simultaneously using a single control signal. The relay interface platform supports an 8 A rated contact current and 250 V AC rated contact voltage, making it suitable for appropriately rated industrial switching applications.
The module features a slim 15.8 mm housing width, screw-terminal connections and mounting compatibility with standard 35 mm DIN rails. Its replaceable relay construction, integrated supply indication and coil suppression arrangement make the Finder 48.52 platform particularly useful for panel builders, maintenance engineers and automation professionals seeking compact and serviceable relay interfaces. The .5060SMA suffix identifies a specific ordering configuration whose additional contact and packaging details should be confirmed against the manufacturer's documentation.

Efficient DIN Rail Relay Interfacing for Industrial Control Panels
The Finder 48.52.8.120.5060SMA is designed to simplify the connection between an electrical control signal and the equipment being switched. When the 120 V AC operating coil is energised, the relay mechanism transfers both changeover contacts from their normally closed connections to their normally open connections. Removing the coil supply allows the contacts to return to their original positions.
The dual changeover contact arrangement provides flexibility for auxiliary switching, status signalling, interlocking and control logic applications. Each contact pole offers common, normally open and normally closed terminals, enabling two separate circuits to be controlled from one relay interface module. The 8 A contact rating makes the module suitable for a wide range of compatible electrical loads, provided the relevant load-specific switching limits are respected.
Its 15.8 mm DIN rail format is particularly advantageous where multiple interface relays must be installed within a limited control panel space. Screw terminals allow straightforward field wiring, while the removable relay and supply indication simplify maintenance and fault identification. For inductive loads, motors and circuits with significant inrush current, the manufacturer's applicable switching ratings and any required external protection should be considered during system design.
