Finder 486181201060SPA – 48 Series Relay interface modules

Why Choose the Finder 486181201060SPA DIN Rail Interface Relay Module?

The Finder 486181201060SPA, formatted as 48.61.8.120.1060SPA, is a Finder 48 Series industrial interface relay module designed for convenient switching and control in electrical panels, industrial machinery and automation systems. Combining a plug-in electromechanical relay with a DIN rail socket, this type of interface module provides a practical connection between control equipment and electrical loads.

Designed around a 120 V AC nominal control voltage, the Finder 486181201060SPA is intended for compatible AC control circuits. The 48.61 relay family features a single changeover contact, providing both normally open and normally closed switching functions. This makes the module useful for auxiliary switching, equipment control, status signalling and electrical interlocking applications.

The 48.61.8.120.1060SPA reference identifies a specific relay interface assembly within Finder's modular range. The 48.61 family is associated with 16 A changeover relay technology, while the complete assembly provides a convenient format for DIN rail installation and maintenance. Before selecting the product for a particular load, the exact socket rating, accessory configuration and manufacturer's technical data should be checked against the full part number.

Practical 120 V AC Control with Changeover Switching

The Finder 486181201060SPA is intended to simplify electrical switching where a 120 V AC control circuit needs to operate a separate contact circuit. When the relay coil is energised, the common contact transfers from the normally closed terminal to the normally open terminal. Removing the control voltage allows the relay to return to its normal position.

This single changeover contact provides flexibility for equipment control. The normally open connection can be used where a circuit should activate when the relay is energised, while the normally closed connection can be used where a circuit should remain connected until the relay operates. Both functions share a common contact, so they must be designed and wired in accordance with the relay's electrical ratings.

The modular DIN rail arrangement is particularly useful in industrial control panels. It provides an accessible interface between incoming control wiring and outgoing load wiring, while the removable relay format supports maintenance without replacing the entire socket assembly. Correct socket selection, conductor sizing and protective devices remain essential for reliable operation.

Why Use a Finder 48 Series Interface Relay?

Finder's 48 Series interface relay platform is designed for installations where conventional electromechanical switching must be integrated into compact electrical control assemblies. Interface relays can help control engineers organise wiring, separate control and load circuits and provide replaceable switching components within an electrical enclosure.

The Finder 486181201060SPA is particularly relevant to systems using a 120 V AC control supply. When specifying this product, engineers should distinguish it from otherwise similar 48.61 modules designed for 110 V AC, 230 V AC or DC operation. The correct nominal coil voltage is essential for dependable operation and to avoid damage to the relay.
