Why Choose the Finder 38.31.7.024.8240 Solid-State Relay Interface Module?
The Finder 38.31.7.024.8240 is a compact and dependable solid-state relay interface module designed for switching AC loads from industrial controllers, PLCs and electronic control systems. As part of the Finder Series 38, it combines a photo-coupled solid-state relay, screw-terminal socket and status indication within a convenient DIN rail assembly.
This interface module provides a single normally open solid-state output rated at 3 A, with a load voltage range of 12–275 V AC. Its zero-crossing switching operation helps reduce electrical disturbance when controlling compatible AC loads, while the absence of mechanical contacts supports silent operation and a long electrical service life.
With a 24 V DC control input, screw terminals and standard 35 mm DIN rail mounting, the Finder 38.31.7.024.8240 is designed for straightforward integration into industrial control panels. Its 14 mm module width provides a compact interface between low-voltage control electronics and AC-powered equipment.

Reliable Solid-State Switching for Automation Systems
Solid-state relay interface modules allow low-voltage electronic controllers to switch AC loads without mechanically operated contacts. This provides silent, rapid operation and eliminates contact wear, making solid-state switching particularly suitable for applications with frequent operating cycles.
The Finder Series 38 module combines an optically isolated solid-state relay with a DIN rail socket and screw-terminal connections. Its zero-crossing output switches compatible AC loads close to the voltage zero point, helping reduce electrical stress and electromagnetic disturbance.
Typical Applications
- PLC and industrial controller output interfaces.
- Heating and temperature-control equipment.
- Lighting and building automation systems.
- Packaging and production machinery.
- Industrial control panels and distribution equipment.
- High-frequency AC load switching circuits.
