48.P3.7.024.0050SPA Finder 1 CO Contacts 24V DC Modular Interface Relay with Green LED + varistor Indication

Why Choose the Finder 48.P3.7.024.0050SPA Modular Interface Relay?

The Finder 48.P3.7.024.0050SPA is a compact DIN rail modular interface relay designed to provide reliable isolation between PLC control circuits and field devices in industrial automation systems. It features a single changeover contact (SPDT / 1 CO) and a 24 V DC control coil, enabling dependable switching of control signals and moderate loads in automation cabinets, control panels and machine control equipment.

This interface relay includes an integrated green LED status indicator together with coil suppression using a built-in varistor. The LED provides clear visual confirmation when the relay coil is energised, while the varistor helps protect PLC outputs and control electronics from switching transients generated during coil operation.

Part of the Finder Series 48 relay interface module range, the unit is designed for installation on a 35 mm DIN rail. With durable AgNi (silver-nickel) contacts and a compact industrial format, the relay provides dependable switching performance for industrial automation systems where reliable signal isolation is essential.
