1pcs RC Absorption / Snubber Circuit Module — Relay Protection Key benefits Protects relays from damage caused by resistance surges and inductive kickback. Reduces electrical stress on relay contacts and coils, helping prevent contact welding and premature failure. Suppresses voltage spikes with an integrated RC absorption network to promote stable, repeatable relay operation. What it does The RC absorption/snubber circuit absorbs transient energy and dampens voltage spikes generated when relay coils or inductive loads are switched off. By limiting peak voltages and current spikes, the module lowers stress on relay components and associated circuitry. Important attributes Function: RC absorption / snubber network specifically for relay protection. Quantity: 1 piece (single-module solution). Performance: Effective at suppressing voltage spikes and reducing electrical stress to improve relay reliability. Integration: Designed to be placed across relay coils or contacts as required to control transients (follow your relay wiring practice). Typical applications Industrial control panels and PLC outputs that switch solenoids, motors, or large contactors where coil back‑EMF can cause failures. Automotive relay circuits (lighting, pumps, fans) to reduce relay wear from repeated switching. Home automation and HVAC relay installations where stable, noise‑free switching improves system reliability. Why choose this module Simple, targeted protection for relays reduces maintenance and downtime. Single-piece RC solution makes it easy to add transient suppression to existing relay circuits without redesigning the control board. Helps maintain reliable, consistent relay performance in environments prone to switching transients. Installation note Install the module across the relay coil or across the switching contacts according to the relay and circuit design to achieve optimal suppression of voltage spikes.
