OKY3485 RC Absorption/Snubber Circuit Relay Contact Protection Resistance Surge Module

The OKY3485 RC filter module is a snubber circuit designed to protect relay contacts and thyristors from damaging voltage spikes. It effectively absorbs the back-EMF generated when switching inductive loads, enhancing circuit reliability and component lifespan.

Key Features
- Component Protection: Protects relay contacts and thyristors by absorbing the induced electromotive force (EMF) from inductive loads.
- Integrated Varistor: Includes a built-in varistor to prevent excessive voltage and current fluctuations, which helps avoid relay contact sticking.
- Wide Operating Range: Suitable for use in both AC and DC circuits with operating voltages from 5V to 400V.
- Load Capacity: Designed to handle inductive loads up to 1000W.
- Improved Immunity: Increases the circuit's overall resistance to electrical interference.
- Easy Installation: Features screw terminals for convenient and secure wiring.

Applications
This module is ideal for circuits that switch inductive components such as motors, solenoids, coils, or transformers. By suppressing voltage transients, it prevents arcing and degradation of mechanical relay contacts and protects solid-state switches from overvoltage damage, making it essential for robust control systems.
