4-pins relais is een multifunctioneel elektromechanisch schakelrelais dat overal in het elektrische systeem van het voertuig wordt gebruikt, waarbij een zwakstroom stuursignaal de spoel bekrachtigt om een afzonderlijk sterkerstroom circuit in of uit te schakelen.

De lay-out met vier aansluitingen biedt een enkel normaal open contact, met twee spoelaansluitingen en twee geschakelde belastingaansluitingen, geschikt voor algemeen schakelen van belastingen zoals verlichting, claxon, brandstofpomp en koelventilatorcircuits. Werkt op het 12V-systeem. Oorspronkelijk geleverd in geel en nu geleverd in zwart met een witte streep.

Frequently asked questions

What is the YWB10027L 4-Pin Relay used for on a Land Rover?

The YWB10027L is a general-purpose 4-pin electromechanical relay used across a wide range of circuits on Land Rovers. A low-current coil signal switches a separate higher-current load, commonly powering lights, horns, fuel pump, or cooling fan circuits on the 12V system.

What replaced the original yellow YWB10027 relay?

The YWB10027L is the current replacement for the original yellow YWB10027. The 'L' suffix marks the updated version, now supplied in black with a white stripe. YWB10027 is confirmed in the alternative codes; both are electrically equivalent 4-pin relays.

How do I know which relay is failing on my Land Rover?

A failed relay typically causes a circuit to stop working entirely, the relay buzzing or chattering, or no click when the load is activated. YWB10027L is common across Defender, Discovery 1 and 2, Range Rover Classic, P38, and L322. Swapping in a known-good relay is a quick diagnostic step.
