48.52.7.012.0050SPA Finder 2 CO Contacts 12V DC Modular Interface Relay with Green LED + diode Indication

Why Choose the Finder 48.52.7.012.0050SPA Modular Interface Relay?

The Finder 48.52.7.012.0050SPA is a compact DIN rail modular interface relay designed for reliable isolation between PLC control circuits and field devices in industrial automation systems. It features two changeover contacts (2 CO / DPDT) and a 12 V DC control coil, enabling dependable switching of control signals and moderate loads in automation panels and machine control equipment.

This interface relay includes an integrated green LED status indicator and coil protection via an integrated diode. The LED provides clear visual confirmation when the relay is energised, while the diode protects sensitive PLC outputs and control electronics from voltage spikes caused by coil switching.

Part of the Finder Series 48 relay interface module range, the module is designed for installation on a 35 mm DIN rail. With durable AgNi (silver-nickel) contacts and a compact industrial design, the relay offers reliable switching performance for automation systems, control cabinets and electrical panels.
