Finder Interface Relay Module 38.51.7.024.5050, 24 V DC Coil, 1 CO Contact, 6 A, Screwless Terminals, DIN Rail

In industrial control cabinets, the Finder 38.51.7.024.5050 interface relay module switches loads up to 6 A using a 24 V DC coil. Its 6.2 mm slim housing saves space on the DIN rail, while screwless push-in terminals speed up wiring. A green LED confirms coil status, and the integrated suppression diode protects sensitive PLC outputs from voltage spikes.

Why choose it

This relay module combines a compact footprint with reliable switching performance. The push-in terminals reduce installation time, and the LED plus diode protection enhance operational safety. It is suitable for PLC interfacing and general automation tasks.

Ideal use cases

• PLC output isolation and signal amplification
• Switching small motors, valves, and contactors
• Building automation and HVAC control
• Machine building and panel wiring

Good to know

The relay is part of the Finder 38 series and mounts on standard 35 mm DIN rails. Its flux-proof design (RT II) allows use in less protected environments. The silver nickel contacts ensure long electrical life under rated load.
