48.61.8.024.1060SPA Finder 1 CO Contacts 24V AC Modular Interface Relay with Green LED + varistor Indication

Why Choose the Finder 48.61.8.024.1060SPA 24 V AC 16 A Interface Relay Module?

The Finder 48.61.8.024.1060SPA is a compact, high-performance DIN rail interface relay module designed for industrial automation, PLC interfacing, machinery control and electrical control panels. Part of the established Finder Series 48 range, this module combines an electromechanical relay, mounting socket and convenient electrical connections in a practical assembly for professional installations.

Featuring a 24 V AC operating coil and a 16 A single changeover contact (SPDT), the Finder 48.61.8.024.1060SPA provides reliable switching between control and load circuits. Its changeover contact arrangement offers normally open and normally closed switching functions, making it suitable for auxiliary control, electrical interlocking, equipment signalling and automation interfaces.

The module incorporates box-clamp screw terminals, an integrated LED supply-status indicator and an EMC coil suppression module. Its 15.8 mm-wide housing mounts onto a standard 35 mm DIN rail, allowing efficient use of control cabinet space. With silver-nickel (AgNi) contacts and a wide operating temperature range, this relay module offers a dependable interface solution for demanding industrial environments.

Installation note: For contact currents above 10 A, Finder specifies parallel connection of the relevant contact terminals, including 21 with 11, 24 with 14 and 22 with 12, as shown in the manufacturer's wiring diagram. Observe this requirement when designing circuits that use the module's full 16 A contact rating.

Reliable Industrial Switching with Integrated Status Indication

The Finder 48.61.8.024.1060SPA provides a convenient interface between a 24 V AC control circuit and a separately supplied electrical load. When the relay coil is energised, the internal electromagnetic mechanism transfers the common contact from its normally closed terminal to its normally open terminal. When the coil is de-energised, the contact returns to its normal position.

The module includes an LED supply-status indicator that assists with commissioning, maintenance and fault diagnosis. An integrated EMC suppression module helps manage electrical disturbances associated with relay coil operation, supporting more reliable integration with nearby electronic control equipment.

Its DIN rail-mounted socket provides convenient screw-terminal wiring, while the plug-in relay can be replaced without disconnecting the fixed field wiring. This construction is particularly useful in machinery control panels, building automation installations and industrial maintenance environments where accessibility and serviceability are important.

The 16 A contact system supports a broad range of switching duties when correctly wired and protected. Engineers should assess resistive and inductive load characteristics, inrush current, conductor sizing, contact protection and the manufacturer's parallel-terminal wiring requirement before applying the full rated current.
