Solid-state relay module Finder 77.11.9.024.8250 in 22.5 mm housing, 1 NO

Finder solid-state relay module in a 22.5 mm housing with one normally open output offers a compact solution for control and switching tasks in industrial and building automation. The module is DIN-rail and socket compatible, providing electrical isolation between control input and switched output. Designed to replace electromechanical relays where silent operation, long service life and reduced wear are required, this solid-state relay simplifies panel layout and supports reliable switching in tight installations.

Advantages

The solid-state construction delivers silent switching and a high number of switching cycles without mechanical wear. Its slim 22.5 mm housing saves space in control cabinets and relay racks. Electrical isolation between input and output improves safety and reduces interference with control circuits. The module's compact form factor and standardized mounting make it easy to integrate into existing DIN-compatible sockets and systems.

Suitable for

• Silent switching of resistive and light inductive loads in automation systems
• Compact control panels and relay sockets with limited space
• Replacement of electromechanical relays to reduce maintenance
• Applications requiring electrical isolation between control and load

Key specifications

• Form factor: 22.5 mm slim module suitable for DIN-compatible mounting
• Contact type: single normally open (1 NO) solid-state output
• Function: electronic switching with optical/electrical isolation between input and output
• Mounting: panel/socket or DIN-rail compatible housing for control cabinets
• Operational characteristics: designed for silent operation and high switching cycle life

How to use

Install the module into a matching DIN-compatible socket or mounting rail following normal safety procedures and power-off conditions. Connect the control input according to the control-voltage requirements of the automation system and wire the load to the solid-state output terminals. Verify correct polarity and ensure load type and current are within the device's allowable range prior to energizing. After installation, test switching operation at low load to confirm correct wiring and expected behavior.

Usage recommendations

Use this solid-state relay in applications where silent operation and long operational life are priorities. Avoid switching highly capacitive loads or heavy inductive loads without appropriate snubbing or protection. Ensure heat dissipation and ambient conditions meet system requirements; consult the manufacturer's technical documentation for detailed limits and thermal considerations.
