Reliable PLC Interfacing and Industrial Electrical Switching
The Finder 48.61.7.012.1050SPA provides a practical interface between low-voltage control electronics and separate electrical load circuits. When the specified 12 V DC supply energises the relay coil, the internal electromagnetic mechanism transfers the common contact from its normally closed position to its normally open position. Removing the coil supply allows the relay to return to its resting state.
This single changeover contact arrangement offers flexibility for control logic, status indication and electrical switching applications. The relay's 16 A rated contact current and 4,000 VA AC1 switching capacity support a wide range of suitable resistive loads, while the compact DIN rail-mounted interface helps simplify electrical cabinet layouts. The permissible switching current must always be selected according to the actual load type, voltage and operating conditions.
The modular Finder 48 Series design is particularly beneficial for industrial maintenance teams and control panel builders. Its slim profile and replaceable relay arrangement make it suitable for installations where space efficiency, accessibility and dependable operation are important.
