48.61.8.024.4060SMA Finder 1 CO Contacts 24V AC Modular Interface Relay with Green LED + varistor Indication

Why Choose the Finder 48.61.8.024.4060SMA Relay Interface Module?

The Finder 48.61.8.024.4060SMA is a compact 16 A DIN rail relay interface module designed for dependable electrical switching in industrial automation, PLC interfaces and electrical control panels. Part of the Finder 48 Series, this complete relay assembly combines a 24 V AC coil, one changeover contact, a screw-terminal socket and an integrated LED indication and varistor suppression module.

The module comprises a Finder 40.61.8.024.4000 relay, a 95.05SMA socket and a 99.02.0.024.98 indication and suppression module. Its silver-tin oxide (AgSnO2) contacts provide switching capability for compatible electrical loads, while the LED provides a visual indication of the control supply and the varistor helps suppress voltage transients associated with coil switching.

With a 16 A rated contact current, 250 V AC rated contact voltage and a slim 15.8 mm module width, the Finder 48.61.8.024.4060SMA offers a practical interface between automation controllers and field equipment. Its complete socket-mounted construction supports convenient installation, maintenance and relay replacement without requiring the entire interface assembly to be rewired.

Reliable Electrical Switching for Industrial Automation

Relay interface modules such as the Finder 48.61.8.024.4060SMA allow industrial control systems to switch separate electrical loads using a low-voltage control signal. When the 24 V AC coil is energised, the relay's changeover contact transfers from its normally closed position to its normally open position. The integrated LED indicates the presence of the coil supply, while the varistor suppression module helps reduce voltage transients generated during switching.

The Finder 48.61 relay interface combines the switching relay, DIN rail socket and coil indication components in one compact assembly. This makes it suitable for PLC output interfaces, control-panel wiring and auxiliary switching applications where reliable operation and straightforward maintenance are essential. For currents above 10 A, the applicable Finder 48.61 terminal-connection requirements must be followed, including the manufacturer's specified parallel contact-terminal arrangement.
