Finder 41.81.7.024.9024 Solid State Relay Optocoupler 5A DC 24V

Rated for a continuous 5 A DC load with a 24 V DC control input, the Finder 41.81.7.024.9024 optocoupler relay switches in under 0.1 ms and handles peak currents up to 10 A for 10 ms. Its 6.2 mm plug-in housing fits standard 90 Series sockets, making it a compact solution for high-frequency DC switching up to 300 Hz.

Overview

The Finder 41.81.7.024.9024 is a solid state relay (SSR) with optocoupler isolation, designed for DC load switching in industrial control systems. It features a normally open (1 NO) contact, a nominal input voltage of 24 V DC (range 19.2–28.8 V DC), and a nominal output voltage of 24 V DC with a maximum output voltage of 30 V DC. The relay provides galvanic isolation of 2.5 kV AC between input and output and operates within a temperature range of -20 to +60 °C.
